Can anyone help me out with this? I’m good with engines but terrible with electrical.
On the new race bike I have an EGT gauge from my other scoot. It was on a battery system but now I don’t have a battery. I have the standard three connector vespa regulator (ground, power in and power out I guess). Anyway, when the bike is running I’m getting 12v power because it will turn on a 12v test light. When I hook it up to the gauge it appears to work while idling but any higher revs and the needle goes backwards!?
Yes I tried switching the power and ground on the gauge to see if it was reversed but same thing happens. Is there any way to make this thing work without a battery?

Without knowing the brand of gauge and a few more details about its design I am just guessing. A battery is dc current , If your stator is one of the new px style it is producing about 80-90 watts AC. I think you would need a rectifier instead of just a regulator to convert the power from ac to dc. Another option is to run one of those really small batteries for RC cars.
