that is correct starter is the only one im having troubles with i got it jacked up but hard to fit wrench or socket in that spot so still working on that but could there be any chance of the starter/solenoid be causing this? cause all wires look good without striping the coating from wire looks as good as one i would go to the store and buy... but the car starts fine everytime..

Have you removed the boots from the end of the wires?

The red things need to be removed for inspection.

the metal washer is fully exposed but did not cut off sleeve to wire should I? the washers are clean freshly brushed..

No, do not worry about the insulation on the wire itself. What we are concerned with is the physical connections to the battery itself. They must be clean and free of any corrosion at ALL ends of the cables. ALL of them.

thats all been done at the battery.. all grounds look solid and been disconnected /reconnected everything looks good but the starter it works fine

Do you have access to a different battery? Maybe a different alternator?

Reason I ask is, some places do not test things correctly. So its best to use another part for testing purposes.

Other than what has been suggested, I don't have any other ideas of what could be wrong.

ok.. well right now i tested original alt failed new one i received tested good 5 plus times i returned it and had the replacement vigorously tested before install its 140 amp passed test tried 3 batterys so far same thing i have all wires coming to battery all pass inspection with flying colors

could it be the starter???? could it be pcm???? this is where i was at when i started this forum all wires have been checked but not replaced yet unless i should for fun new batt new terminals new alt what else is involved in a charging system that i am missing? it dies while driving and wont charge for sh*t but starts back up.. so should i post it under the for sale or parts on this site?, never had a Bonneville rub me this wrong

Let'* try this. Can you make a jumper wire that will run from the output terminal of your alternator(not the big one, but the little one) and run it to your battery +

Basically, what is done here...

is that the harness to alt? if so it has one wire in it where does that go from alt?

Splice your jumper into that 1 wire from the alternator and your going to connect that to the + of the battery. NOT the negative. Only do this while the engine is started. What we are doing is bypassing the charging system of the car and showing the alternator the true voltage of the battery.
