I have a '57, 235 with generator and the ammmeter needle stays centered and only momentarily jumps to the positive side for charging then goes bck to center and stays there. | | | | | Joined: Dec 2006 Posts: 1,464 Shop Shark | | Shop Shark Joined: Dec 2006 Posts: 1,464 | There's an extensive adjustment procedure in the 55.2 shop manual that you can link to in Tech Tips, but it sounds like maybe your system is operating normally. The main thing is - does your battery seem to be fully charged and are your lights nice and bright and not flickering? | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | Like Waldo say's it probably is normal. When the bat is fully charged there is no curent flow & the gauge stay's in the middle. If you turn on the lights It will go to discharge at idle & if you accelerate it will go back to charge & back to the center. A good test is to get a volt meter & put it across the bat. term. on the reg. & ground. Acel. the engine & it should read between 13.8 & 14.5 volts.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
