6Volt to 12Volt

[1965mod]

Hi, some of you may have seen the GS160 I'm restoring in the 'Introduce yourself and your scoot' board and I would like to convert it from 6V to 12 V if possible. Is there a kit available for the GS and if so where do I get it from. I've looked on the websites that I know of and tried the normal Google thingies but no luck so far.

Any help would be much appreciated.

think theres a kit available from one of the either vietnam or siaggon dealers,there website is listed in scootering mag,not that expensive either.Let me know if you find it mate-if not i'll try dig it out for you.

You can find the ScootRS website via the vespa.org.uk directory:

Thanks for that. I've emailed ScootRS and the Saigon Scooter Centre to see what they can do. They both do conversion kits but I don't think they are for the GS160 - not from what I can see anyway. I'll come back here if I find out anything but its a shame I can't get anything in the UK though

[Spence]

Have you tried the VCB or the VMSC? There's links to both on our links page.

www.vespa.org.uk/Links.html

[1965mod]

Well both ScootRS and SSC have replied saying that they do not do a conversion for the GS160 so I will try the other links you suggested Spence - thanks for your help by the way.

Well I've had no luck with a purpose built 12V conversion for the GS160 so I've bitten the bullet and ordered a VBB version from ScootRS and I'm going to attempt to modify it for the GS, God knows how I will get on with it but I'm going to give it a damn good try - I'll let you know how I get on (or not!) - wish me luck ;D

Keep us informed on this one. I need a new flywheel 65 Sprint as mine has no vanes left on it. I'm thinking of going 12 volt. Can get the kit but have new loom for bike which is 6 volt. Do I need to get a 12v loom or is there a small loom with the kit? Ian

[1965mod]

I received the kit from ScootRS yesterday (a day early!) and I'm very impressed with both the quality and content, nothing looks cheap or tacky like I was expecting and everything has been included and I mean everything, even down to a brand new light switch modified for the 12V system and a new ignition switch all pre-wired.

I opted to go for the kit with a complete new loom so as to make the installation as easy as possible and also with a safety aspect in mind of knowing that all the electrics will be new - they even supplied all 12V bulbs including a 35/35W halogen headlamp.

My biggest nightmare will be adapting the stator plate and flywheel to the GS but I am determined to make this work - I don't care how long it takes - I will get it to work

lets not forget that if 6 to 12 is all you want (ie not electronic) then beedspeed can alter your stator plate for a vwery reasonable price.

PS . welcome to the cold weather everyone, hope your gloves are warm ;D

hi been watching with interest . hope the kit works out for you ok .

i've just got one for my 64gl . can't seem to get much in the way of help anywhere at the moment . just in middle of joining the Veteran Vespa Club .


have you had a go at fixing it yet ? and did the kit come with any instructions ? mine didn't and all the guys i know have lammies so are not much use .

i'd really appreciate a bit of help if you can find the time , its really frustrating the hell out of me . i'm not very experienced in this sort of thing nad i can't seem to nail it . i dont want to botch things up

cheers

Hi, I wish I had some good news for you but at the moment I haven't. The actual items are of very good quality so thats something but I tried laying the loom out on the kitchen floor and pluging in the associated items using the supplied wiring diagram but it didn't make sense at all.

I won't bore you with the details but an example is they (ScootRS) supply a new pre-wired ignition switch with the kit, the problem here is that the ignition switch shows only 3 wires coming out in the wiring diagram but there are 6 on the switch supplied, an email to ScootRS resulted with a reply "Just use 3 of the wires then"
Another email back to them asking which ones and no reply
On the wiring diagram it shows a purple cable - there is not one purple cable on the whole of the loom, ScootRS have still not told me why after several emails to them.

In the end I've told them I will sort it out myself, great product - crap afterservice.

It is advertised as a plug and play conversion if using one of their new looms to re-wire your scoot complete - Oh realy!

It's things like this which make me even more determined to actually do it, I haven't even tried to fit the stator and flywheel yet, I just know there will be a problem with something because it was never designed to fit the GS but fit it will - and work ;D

Once I've got the flywheel and stator fitted I shall lay the new loom outside the scoot and wire it up that way so as not to disturb the original, gradualy connecting individual items up as I go.

Graham

[64gl]

cheers for that .

i'm going to have a look at mine tonight and see if starts to make any sense .

real problem i've got is that i don't know which order to wire them up .

i've got wiring diagrams coming out of my ears , but none for a 12v conversion !

could get loads from others with lammy's , but none for a vespa .

your machine looks superb . i'm sorting out some pics of mine and will post them as soon as i can

[1965mod]

I'm not sure if this will help but here is a link to a 6V - 12 V CDI ScootRS wiring diagram, it might not be exactly the same as yours but it might give you some hints.

Hope that helps a bit and good luck.

Graham

[64gl]

cheers graham ,

great help . not totally confused now , this should be a piece of cake ! lol

i'm not going to drill through though . i've bought some steel sheet from B&Q and i will make a bracket for the CDI and regulator . there should be enough room in the engine compartment not to have to drill a 42 yr old frame .

i'll let you know how i get on .

thanks again

No problems Vince, glad to be able to help.

Good this forum init ;D

After thinking that I had completely lost the plot in trying to figure out all the connections to the loom, I got this email completely out the blue from ScootRS this morning:

"It seems after looking at this that you have the wrong loom, sorry. You
need the single loom. (I'll be updating that diagram slightly to make it
easier as well, so check back when you get the new loom.)

I'll arrange to send you the correct loom tomorrow.

Thanks.

John"

OK, so they c**ked up in the first instance but that is a great and honest recovery.

Well done ScootRS.

[64gl]

has it arrived yet G ?

still havin a mare with mine . gettin some help from a neighbour who's an auto electrician .

tried to follow the diagram , but different colours and ait seems a slightly different loom aren't helping !

have a look at this if you've got time . useful diagrams and a bit of fun

Hi m8, no not arrived yet It will be a while yet as it's got to come from Vietnam which normally takes about 5 working days so not until next week at least. I have got permission from 'er indoors that I can work on it (the scoot) Saturday so the first thing I'm going to do is attempt to put the stator and flywheel on - that should be a good laugh ;D. Thats the hardest bit - if I can sort that out then I know that once the new loom arrives then it shouldn't be to bad connecting up - famous last words!

If - no when - I get this electrickery thingy sorted out then I've got some interesting little 'features' planned which will get all the traditionalists up in arms but hey ho - it's my scoot so am I bovvered

Any news m8 and I'll let you know.

I took the plunge today (Saturday) and took the old flywheel and stator plate off to see how on earth I was going to fit the 12V VBB version, it was obvious that neither the stator nor flywheel would just drop in so a plan was made.

The first thing I decided was that if it was going to fit then I would do all the mods to the stator and flywheel and not the original engine, so with that in mind I took the new stator apart until I was just left with the aluminium base plate (taking pictures at each stage so I have a record of where things go), the central hole was far too small for the plate to fit flat on the original 3 lugs so I took out all the surrounding metal untill it located and layed flat on the 3 lugs, screwed in the 3 screws loosely and then carefully fed the small wiring loom through the base plate and out of the case, then assembled all the coils etc to the aluminium base plate. Before tightening the 3 screws I checked that none of the wires were being trapped behind the base plate. Thats the stator taken care of. ;D Seems simple now that I've written it but it took me about 4 friggin hours!

Next job is the flywheel. The tapered hole is too small to go on the GS shaft - well it would be wouldn't it, it wouldn't just fit on - so I'm going to take off the tapered part from the new flywheel and throw that (it's just riveted on) and put the existing adapter onto the new flywheel, it will require machining a larger central hole with a small recess and drilling three fixing holes into it so I will do that next week by which time my new loom from ScootRS should have arrived (hopefully).

I've also bought a secondhand VBB headset with a square switch housing for the lights etc to replace the GS headset. This is because the kit comes with a modified light switch and new ignition switch. A job for tomorrow is to assemble all this lot including the speedo with a MPH refurb kit as I didn't want to replace my existing speedo with a remade version.

More to follow when I have more news.

now then m8 . got my kit on , bit of fancy bracketting was needed .

fired up great . just trying to get the timing sorted out now . lights like blackpool illuminations !

didn't go through frame under petrol tank , i decided to go under rear mudguard and tuck under rear light tube .

uses some super strength velcro to help secure cdi and regulator to the bracket , more of a plate really . these velcro pads are v cheap and can hold 4K weight . ideal if i need to remove them for any reason without having to always unbolt loads of things .

i'll try and post some pics soon

good luck mate

[1965mod]

That's excellent stuff ;D

Since last weekend I've had a mate machining the new flywheel to accept my modified GS adapter flange, last night I measured up the approximate rotational position and it fitted He will be bringing the completed assembly back to me on Saturday finished with the flywheel bolted to the flange so (touch wood) that should be the mechanics sorted.

I won't be able to go any further though because the friggin loom has still not come but I'm told that it is on it's way but getting there slowly which is the main thing I guess.

Graham

[64gl]

superb .

i'm just going to have another slight adjustment of the timing and then i'll be away .
its a beautiful day here today (sunday) so if i'm quick i'm goig to get wrapped up and go for a pose !

hope the loom's quick ;D

[1965mod]

Good news and bad news.

The good news is that the stator plate and flywheel are now complete and are now on and also the loom came Saturday so I was able to do a quick wire up to see if I could get a spark - thats where the bad news comes in. No spark - yet

But at least I've now got all the makings together and it should be slow task now to get the bugger going. It would have been good to get a spark the first time round but I kinda guessed that it wouldn't be that simple.

More to follow once I get a spark.

Graham

[64gl]

i had the same thing mate seemed ok , but no spark .

i know it sounds obvious , but i just missed having a good earth for both the cdi and regulator

[64gl]

G ,

all done now mate , just waitin for some good weather .

timing sorted .

hope everything is going ok with yours ?

A

[1965mod]

Hi A,

Glad you're all sorted mate, thats excellent news. I haven't done much more on mine to be honest. Each weekend seems to be taken up with something going on at the moment but with 10 days off at Christmas I hope to get something done - I've got to get something done if I want this up and running for the Spring/Summer - I'm starting to fall behind a bit now

Safe riding,

G

[64gl]

G ,

you too mate . glad i've done now .

My scoot is in the christmas edition of scootering on the YSA tadcaster to wetherby rideout .

its the cream vespa on its own with the front rack and double seats . i tried to post a pic on here , but the file is too big .

have a good one

I can't believe it was last December I posted, I basically got fed up trying to get a spark out of the 12V system and left the poor old GS covered up at the back of the garage but on Sunday I thought I would have another go. To cut a long story very short it turned out to be an earth wire from the ignition switch not attached - I now have 12V Electronic Ignition on my GS ;D. That has spurred me on now so progress is going to start again - I'm sooooo happy.
