My starting voltage depends on the weather lol, but it's 15-15.2, settling to 14.8 in the warmest weather. Days like this, I'll drive around at 15.2 for hours lol.

I was gonna do my run for alternator to the back

Yea do 1 run from the front batt to back batts then do the other run from the alt back

I agree amd it does dip down to resting votage at idle but while driving never below 14.2 which is .9 drop

little spikes drawing more then the alt produces don't even last long enough to reach resting voltage maybe ..? Idk lol but that alt is basically keeping up

Ok so what I got out of this is 3 runs of positive and negavtive, 2 SAMs clubs batts in back and a better one up front ? I gettin this right?

Hey the more power wires you add to the alternator the more you have to ground it and and the engine right?

You want to have equal amount of power and ground runs

So I need 2 power runs on alternator and 2 ground runs on alternator and 2 grounds on engine?

No i mean equal runs from front to back ..up front u wil need a pos from alt to batt..then a ground from batt to alt case then from batt to frame

You will be fine with one pos and neg run back from front batt .. And then one pos run from alt to rear bank

So two positive runs from the front to back and one ground run from the front to back ,

I know it souds crazy but I'm just tryin to prevent a fire lmao, yano like running a 4 gauge power wire and a 8 gauge ground wire, that kind of fire for example

 

[bgordon]

I'm jus trying to have equal power

My winter ride has the craziest voltage I ever came across. If the car is actually moving my voltage is 14.9 dips at full tilt for awhile 13's with stock alt. But if I park and give a demo, it's way down and my lights dim and all even if I put my foot on gas to 2-3k rpms it don't change, anyone figure that out? Is my car regulated or alt going bad? It's a 99 Pontiac grand am on AB 120.1 . 1 1/0 from alt straight back to kinetic 2400 same from alt to kinetic up front than back big 3 and what not.

 

[bgordon]

Not saying more runs would help u but i dont consider dropping into the 12s good voltage ..i drop to 14.2 full tilt
