Voltage regulator on the alternator could be shot. Get it tested. See what it's putting out

Edit: read the original post. Same response. Test it again. It can't be over charging the battery if the alt tests fine. Your literally seeing what the alternator is charging the battery at. It doesn't recharge on solar energy. I promise

What is the charging voltage? You did check that, right?

Mikeythrash

Yeah said it earlier in the thread 770 cca

Parsnip

Not cranking amps, charging voltage. As in what is the alternator putting out

Mikeythrash

Ill find out and ask if he did that

Mikeythrash

He just said he thinks it was 15

Mikeythrash

Tested to 15 then over charges to 19 and this the second battery

Mikeythrash

15 then over charges to 19

Yep, that is over charging alright. You just might need to replace the ECM, but check the wiring between the alternator and the ECM first.

Mikeythrash

So.you said check the wiring well I did there was a msd ignition box hooked up which was takin off by previous owner before me.but left that horrible dangerous wiring there.could this be causing it? I mean u start it starts right up rev it up to 2k rpms and that battery gauge just flys up fast too.

Mikeythrash

He said when he got it he had to keep charging the battery on his way home looked under the hood and noticed the alt was unplugged obviously because the *** that sold it knew it overcharged.and I am thinking it has to do with that wiring pcm seems fine

that looks like a horrible mess. Idiot PO's for sure...you're going to have to remove all that junk.

Mikeythrash

Yeah I am going to I think thats whats causing it what an idiot.u think I can just pull those wires out or do I need to totall start from scratch

Mikeythrash

Any suggestions
