I have a Sunpro hour meter for my Kawasaki engine, where would be a good place to get 12 volts when the key is in RUN position only? Also, the volt meter only works when the key is in the accessories position. I had it running off the original charge warning light line thinking it was for a charge meter. That explains why it would only work in the acc(or test) position and not work in run because there is suppose no volts going across that line when it is operating correctly. Any ideas?
