Hey FABO,
It's been a long time since I've posted! As I've been living with no garage the past 3.5 years I hadn't gotten around to much in the way of car work--that is, until last weekend. Finally swapped out my cracked & clogged stock radiator for a shiny 3-row champion unit. While I was at it, went ahead and switched pulleys to the correct non-AC setup.
On to my question. Since putting on new pulleys, the voltage drops down to ~12 volts when I put the car in reverse(also drops in drive, but not as much). Reverse is probably at around 700 rpm. As I had problems getting the single-groove pulley pressed onto the alternator during the swap, I tried a new alt tonight but with no effect.
The new crank pulley for water pump/alternator seems smaller than the old setup, so is this just the max the alternator can put out at 700 RPM now? Or some other fixable problem that others have seen? Other factors in play: did the ammeter bypass about a year ago and added headlight relays, but the issue does seem worse with headlights on.
