So I have a 400Watt inverter powering up my carputer right now, and there is a problem.
1. It will do a very high pitched WEEEEEEEEEEEEEEEEEEE noise after about 15 mins and it will last until I turn it off any ideas?
2. If I leave just my inverter on, will it keep draining my car's battery for 400W even when my computer is not on? Because nothing is using up the power so where could it go? I know a 400W is probably a overkill to power a PIII 666 computer, but I was hoping I could power something else if i needed it.
Any help would be greatly appreciated.
