It is a cheap inverter. Measured for 100watts. I used 14 awg wire to connect it.

I'm positive i got the polarity correct. The + has a fuse on the PCB and the - doesn't.
I tried drawing from several sources.
1) ACC line for rear cig lighter.
2) New line ran for Amp.
both to no avail.
It does this with the car running and not. I mean I have been running my battery down lately, but I start it up for a few min every once in a while to let it charge. Like i said I measured the voltage and everything seems fine.
