RE: 90 AMP to 115 AMP Alternator Upgrade
That is normal Mark, if you want to do better, get a smaller pulley for the
alternator, 87 and up cars had it. The smaller pulley allows the alt. to run
faster at idle.
The conversion is a bit of an involved task, not a direct bolt-on, I think
Dewitt from CO. did it.

Subject: 90 AMP to 115 AMP Alternator Upgrade
Anybody upgrade their alternator to a 115 AMP. Leastways that's what
I think the high output generates. This is for an '86 5KCSTQ. With
everything running (rear window defrost, blower on high, headlights,
etc.) I only read about 12 volts, sometimes less. Running down the
road I get 13+ volts.
Any thoughts or BTDTs appreciated.
