High output alternator

gents, looking for some assistance. i have the 170amp alternator, AC DELCO 92254798.

When driving, i see ~13.5V or sometimes less than that. I am thinking that i need to upgrade to something more like 200 or 220 amps.

Anyone know what or whom makes a HO alternator?

Re: P2135 and Reduced Engine Power

I am getting something similar but have not been able to figure out the source. in logs i can see there is a large difference between TPS1 and TPS2, but wires, TB and tune all seem to be agreeing.

Re: TPS1 and TPS2 disagree...P2135...need some help getting data for baseline

today a new TB arrived, tested it and it appears to give nearly identical % and V at the same perimeters. here is the log. the only difference i noted is that the min voltage for TPS1 is showing 0.61V and TPS2 at 0.57V....not enough i would think to prevent things. again logs are attached. I am hurt...

Re: puzzeled by brake switch status

Even though you probably don't have ABS on the C10 could the ABS system, internally, be looking for the brake position signal? Is the ECM looking for the ABS? Just guessing here... Maurice possibly, but if so, i have no way of spoofing the PCM/ECU to make that happen. driving it longer distances to...
