1. Fresh rebuilt AC Delco Alternator-13.3-13.8 Volts output at idle-verified by Powerlogger and Scanmaster and by rebuilder on test machine...new regulator was installed for rebuild.
2. Brand new Casper Volt booster-verified working by John @ Caspers on his test fixture.3. Properly functioning TPS-no flat spots .42 idle 4.7 WOT on Scanmaster & Powerlogger
Made a log with PL at 16 lbs boost with 4.5V WOT TPS and volts stay at 13.8V per Powerlogger log info and scanmaster as well.
things I have tried:
1. Replace TPS-no change
2. Car idling with Powerlogger hooked up monitorong Volts I went and manually pushed the TPS lever
down to get it to go past 70% TPS voltage,which should cause the Volt booster to send another 2.2V or so to the alternator and show up on the PL and scanmaster--did this and nothing. (John Spins as my wqitness as he did the test with me).
3, Tried another volt booster brand new out of the package at Caspers office-same thing-not working
3. Lights on WOT pull do not get brighter
I'm stumped--any ideas out there??
