charging system
I recently bought a 69' F-250 with wiring issues. Electrical is definitely not my strong point but I have been gritting my teeth and diving in. My issue is that my ammeter constantly reads discharge! The higher the R.P M. the closer I get to charge but never make it! Have used wiring diagrams from this site and as far as I can tell I have repaired all spliced and wrong wires properly but cant seem to solve the problem. I am positive it is something simple that I am overlooking. HELP!!!

Re: charging system
Since you say that it gets closer to the charge side when you rev the engine, it kind of sounds like the gauge is out of calibration. You might try a new gauge. If the battery seems to stay charged then yes you have a bad gauge. I would put a voltmeter on the battery and see if the voltage increases when you start and rev the engine. If it does then you know it's charging at least some.
