Update to my voltage issue.... I posted here last week about my car having a hard time keeping the voltage up. At the suggestion of a few members, I got new cables made (0 gauge) and put in a larger battery. It seems to do much better now, but theres a possible new issue: My voltage drops under hard acceleration. I just installed a volt booster from caspers too, so I have to remove that and see if thats it because it didn't do this before. I'm beginning to think I have yet another bad alternator.....
Just a little background: Yellow top in stock location, 145 AMP alternator, 0 gauge cables, and only minimal electrical draw (fans, ecm, FP, WB).

Bummer. I have been watching and struggling with you. It looks like mine turned out to be a bad fairly new starter.
We had a problem with the Casper on one of the cars here. It would freak out the PCM and flake out the 5v feed and sensors would miss-report.
keep up the report man!

I'll probably get it out tonight and see whats up. I'm still dropping to 12.5-ish volts at idle with both fans on, which IMO is liveable.
How did a bad starter cause your problem? Isn't it basically out of the circuit once the car is running?

Take that caspers thing out of there, that just seems like trouble to me.
You could have a bad ALT right out of the box. Not common, but possible.
Please educate me, is there a voltage regulator in our cars that I don't know about, could that possibly be the culprit?

The Caspers unit only increases voltage at 70% or greater TPS voltage. I didn't buy it to help this problem per se, more of a safety thing really. More voltage for the FP and stuff at WOT is good.
Plus, KP runs one. I pretty much take what he says and run with it.
"I wanna be wanna be wanna be like KP" <----you gotta sing that like the old Michael Jordan "I wanna be like Mike" commercials.
