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.
As far as shipping goes don't you live right next to the border? There are companies in Blane that will accept packages for you and charge you a buck or 2 without having a PO box there. I use TSB Shipping in Point Roberts as it's closer to me. Worth the trip and gas is cheaper there so I always fill up at the same time ;D
