Problem with load from inverter.
Hey guys, to start I'd like to say thank you, I've got a lot of great information from this site over the years. I haven't really been able to find a reason for my most recent problem, though, so I thought I would ask.
Pretty simple setup:
'05 Cobalt with an aftermarket head unit (7" screen, AUX input, etc.)
1000w (1500w peak) rated inverter.
So, I connected the positive wire from my inverter to the battery and grounded to the frame (clean connection). I plugged the PS3 into that, and the PS3 into the screen and turned it all on. Success! It worked great. I turned it all off, and started my car. Turned the inverter and head unit on, turned on the PS3 and my inverter kicked out and reset itself. So I tried it again, same thing. So I turned off my car, turned on the PS3 and it fired right up.
I'm trying to make sense of this. The output of the battery while the car is off is maybe slightly over 12v. When I measured it while the car was on, it was getting the ~13.5v from the alternator, which was well within the inverters rating of up to 15v input.
