My battery keeps running down. I can charge it right back up with my charger, so I think it is OK. After I charge it up and begin driving my gauge says 13-13.5 volts. It starts decreasing from there. Down, Down slowing as I hit the brakes, turn on the air with the fan, radio etc., to near 10 volts. If I turn the head lights on they are steady and bright. I believe they are connected directly to the alternator, not thru the regulator. So I think the alternator is OK. That leaves the regulator, which I think is bad, and just not charging the battery. I think the battery slowly runs down as it is running all the lights and accessories(except the headlights). It gets worse as the engine gets hotter. Anyone have any thoughts on this. I hate to replace tha alternator if it is only the regulator.
