Adding spotlight to non battery PX

[hully1]

This may have already been discussed but is it easy enough to add an extra spotlight to a non battery PX or will this put too much strain on the electrics?

Your best off with golf caddy battery in the glove box the ac supply only just keeps your lights on as it is

[hully1]

Hi rab, just as i thought have seen a 12V 20Ah battery on line for 35 quid so cant go wrong with that.

cheers Hully

[rab]

Thats a good price for 20 ah fella im running a 17 ah it has alarm 3 spots and twin air horns running off it and i only give it a charge once a. Month . It should give you at least an hour on just the one spot constant use if not longer i get about 40 mins off mine .i may yet tap into an ac live to keep it charged when its not in use just need to get the time

[hully1]

charging from the AC set up is that a complicated job or just time consuming? What are the best bulbs for low power consumption LED i would guess?

[rab]

led are best for the least power consumption but there dc ive heard people say they've had them working off ac possibly nik or H. i would have thought just a fused wire from ac supply to battery as the battery lets out a dc current but unsure its one ill be asking in forums before i do it but id say very straight forward easy job. as for bulbs my spots are halo lights(led) with halogen main bulbs 33 watt i think but halogen use the most power

To charge a batte…ry the stock set up is somethng like this....
Ac supply from stator connected to a 4 or 5 pin rectifier/regulator, connected with fuse to charge battery...you may even, by chance, already have a 4 or 5 pin rec/reg (theyre pretty cheap anyway) which would mean simply adding a battery and a couple of wires,fuse the positive wires.
There are other ways but the stock way seems simplest and best to me

That's how I'd do it too. use standard Piaggio parts and then you know what you're getting if it goes pop.
Run from the battery through relays to be on the safe side.

As for LED bulbs, I'm running a PX tail light with one at the moment, and that's AC. You're right, in theory they shouldn't work, but they do. I put it down to the speed which the current changes polarity being too high to affect the running. I could put a clipper diode in the line to smooth the current, but TBH it seems too much hassle for no real return as it's running 12V, not peaking above it..

[rab]

So realy we could use a live from the loom behind the horncast to charge the batery in the glove box when the scoit is running as long as i fuse it ? I know its not how it should be done but if i placed something inline like a diode to stop any current feeding back down the ac line would it work ?

[hully1]

Could always fit a plug in diode before the fuse which would stop any current leaking back?

A DC battery needs a DC charge. This is one of the things a 4 or 5 pin reg/rectifier does.converts ac to regulated 12v dc.which can charge a battery. Dont hook up your battery direct from your ac supply without one/somethng similar.
So nik,did you just plug in LED buld and it worked? Is it brighter?  Have you tried one in the headlight at all? Are all LEDs dc?

[rab]

4 pin rectifier it is then

[hully1]

does anyone have a wiring diagram for this mod?

[kru251]

I must admit my 5 spotlights (wired as one switch for the three white bulbs and another switch for the two yellow fog light ones) are powered by a 12v 22amph battery like this:-

Lucas Battery

Works fine on the' total loss' system. Neat, simple and no chance of it screwing anything else up!

LEDs are inherently DC, you can't make an AC one, so yes. I don't think it's any brighter, but it's putting less drain on the system, so theoretically "freeing up" wattage for the rest of the system. I'm after an LED side lamp next, but I'm not going to try a headlamp, going for a HiD 35/35 there instead.


As for the battery conversion: Replace the three plug regulator with a four/five pin one. From the DC out, run a line to a battery (9Ah is normal) and then back from there to the lights/switch/relay set up. Stick a fuse inline to the lights, job done.

Cheers Nik,

looks like a job for the winter when the snow is around my knees!!

[rab]

I followed what kru had done before me and with his simple wireing to a battery saves loads in time and cash and doesent draw from your scoot power supply. im only going for battery conversion for the rear marker lights im fitting and at the same time run the indicators from it so i have no more headlight drain when i use the indicators

I'm reviving this old thread as it popped up during my research on adding a battery.

I'm doing a rebuild of my Mk1 T5. It didn't originally come with a battery, I added one back in the 90's just to power my stereo system. It didn't charge on the scoot though, I charged it as needed. 

The battery, the tray & the stereo are now binned but I'd like to add a battery for lights, like the OP, I want to add some LED's. 

Some questions - 

Is it as easy as the quoted text above? Is there anything else I need? I found this loom & as I'll be replacing all the wiring, is this the best thing to use? 

Thanks for reading & TIA for any incoming help.

Cheers, Neil

OK I have not long converted to full dc so I can use led lights. I bought a bgm loom and regulator and a lithium battery, just followed the instructions with loom and regulator and found it easy, and I hate electronics
