So I'm driving the black beast (1989 f350 CC SRW 2wd ZF-5) because a) less miles on my truck, b) it has functioning AC, and C) because if the ZF it gets 18mpg easy, which I can't get in my truck.
Anyways the voltage gauge (stock I know I know) has always been a kittle goofy. If I turn the fan speed from nothing to full it drops way down at idle, and comes up if I rev it. I didn't think much about it since all the other gauges are a little goofy as well.
But tonight I caught onto something. Sitting at idle with the lights on and ac going full boar, the lights are kinda dim. The voltage gauge is reading towards the 9v area. If I reced it, the lights would get brighter and the gauge would swing back to the 12v area. If I turned the ac off it would also get a little brighter as well.
What do you guys think?
