My stock alternator wasn't doing its job. I couldn't run the wipers, heater, and lights at the same time without everything slowing down or getting dim. So the amp needle would be on the negative side a lot, especially when I step on the brakes.
So I replaced my alt with a GM 135amp beast! I followed directions from the web to a T. I got everything hooked up correctly (far as I know). The cruiser runs great only problem is that the amp needle fluctuates from positive to negative now depending on the RPM.
So here is my problem:
1. At idle no accessories on: amp needle is below the mid mark on the negative side. (Volts @ battery <mailto:Volts@battery> 12.7)
2. RPM 2000 no accessories on: amp needle midway on the + positive side. (volts @ battery 13.99)
3. At idle all accessories on: amp needle pegged on the - negative side. (volts @ battery 12.16)
4. RPM 2000 with all accessories on: amp needle midway on the + side. (volts @ battery 13.96)
Why does my needle fluctuate between + and - so much? The battery volts never drop below 12?
Thanks,
Rodney
