"Accessories" causing rpm to drop
Sitting in college parking lot and turned on lights just to see if they would turn on (been having electrical problems) noticed the rpm's drop and heard it too pulled on fogs and dropped more. Turn blower on to 4 dropped to almost 600 then a relay type clicking sound was made in engine bay and rpm's spiked back up to keep it from stalling out. I have been having trouble with gauges last couple of days the keep on doing the sweep or get stuck all the way maxed or stuck at minimum. I figured this rpm dropage migh be linked? What are some ppl's thoughts? (Sorry if I'm in wrong area of forums on my IPhone in car and going off memory for forum category) I was think IAC or maybe Alt but did a load test here at school and alt passed it. Also my battery light (charging system) keeps coming on and off. Hope someone knows what's wrong not taking to a shop becuz one hate doing that and two just spent all my $ on a SPA turbo kit for the car.
