Gps speedo on regulator

[rab]

K I've got basic 2 wire gps speedo wired direct to the regulator dc and it's playing up has been working fine but now decided it won't turn on when lights are on and when I turn lights off it flickers unless I rev the scooter tried replacing the regulator to no avail its 12 to 24 volt so isn't over loading the speedo in fact way it's acting is like it's not getting enough juice. I had same issue on my old stator that I've just replaced so I'm at a loss now. Any suggestions guys

Hello.

When you say regulator DC, do you have a battery fitted? If not that could be the problem. I used to run without the Battery as I had dumped the starter motor. Someone here pointed out that the regulators eventually go wrong as the Battery stabilises the output.
