I'll have to check the amp and guage battery after work. To get it to stop, I had to pull the batt cable.

I'll look in the archives to see some past advice. What I would like to know is if there is a way I can logically rule components out without replacing them.

From my little knowledge, it is likely the battery, ignition, or wiring (maybe). I can't see how it could be a grounding issue, because a bad ground would not let this system engage at all, right? So how to check the battery or ignition to rule out...
