Seriously Need Help
Notice amp meter about 3/4 charge and bouncing with blinker and going below strait up at idle. Wow it acts like a generator does.
Three quarter charge is a major problem. That's approximately 30 amps going to the battery. Something will overheat and start to melt if that continues for more than a couple minutes. The only question is which things go first.
It could be the battery charge is very low, or there is something wrong (or modified) in the electrical system.
ANother possiblity is high voltage causing battery to draw more current (over charging) but it
seems you have disproven. The check which
I think you have done is to
measure voltage at the battery while the
ammeter is showing 30 amps charge.
Headlights even dim then brighten slightly at acceleration ( back and forth). Tried two different new voltage regulators with no avail,
They will dim or brighten with voltage decrease and increase at the filiments. So this is a clue but alone isn't telling us much.
Another guess here: One or two of the field windings or diodes has failed. So now the alternator is producing a choppy output and insufficient to recharge the battery and run equipment (such as blinkers) at slow idle.
Alternator putting out 40 amps,
tried a different one with no avail.
How do you know it was putting out 40 amps?
If you mean it produced 40 amps at 15 V with the engine at 1250 rpm (FSM test) that's very different than if you measured 40 amps with a clamp meter while the engine was idling.There is no reason in the world for the alternator to put out 40 amps while idling other than the fact the battery is sucking 30 amps. Of the remaining 10 amps, 5 are typically what the field and ignition draw.
By passed the amp meter, that’s not the problem. Electrical system holding between 13.5 and 14 volts.
Of course not.
What the ammeter was showing you is that something on the battery side of the meter is drawing a lot of current. Dead battery, damaged battery (plate shorting), Electric fan added, or possibly even a wire shorting.
Battery is good, checked all grounds and connections.
How was the battery checked?
