I'm not sure if this should be in the audio forum, so if its better suited over there I apologise. The problem is as follows. I'm getting a bump through my sub whenever I draw power anywhere else, like when I turn the headlights on, power windows or locks, manual fan switch. That and my voltage gauge in constantly reading lower than normal. But when I slide my vent selector from off to defrost it really freaks out, the lights dim and the voltage drops WAY down for a sec. From my experience this can be traced to bad grounds, but I cant find any visually.

Any idea's?

Thanks,

 

I've checked the connections at the battery, alt. and my stereo equipment. The battery and alt. are both less than a month old, and my alt output gauge (sunpro) shows 14.7V at idle. My factory gauge shows at or less than 12V at idle, where as both gauges used to run in similar ranges ALL the time.


Thanks,

 

Haha, yes it is quite apparent that something has malfunctioned. Tomorrow I begin the task of fine tooth combing. Perhaps it will be a simple fix, though it seems it never is.

Thanks,

 

Well, I found a questionable ground on my fan switch. It was there, but weak.

So far thats it...


Any Idea's?
