I have a walmart brand prestone 300 watt dc to ac power inverter. I am building a mp3 player in my 1996 chevy blazer. I put the power inverter in the back and ran the ground wire straight to the frame. I ran the power wire up to the front to a switch that has a build in led and from the switch to the power wire on the cigarette lighter plug.

When I flip the switch to power up the system the led comes on but the inverter will not come on. I can take the inverter and plug it into the cigarette lighter plug up front and it will work fine whats the problem???

Two questions:
1. What gauge wire are you using and how long is it?

2. If you have a 300W inverter, you probably have a 30A fuse on it. Is your switch rated at 12VDC@30A?

Gutter, I am using 14 guage wire and my switch it a glow dot toggle switch rated 12vdc@ 16amp.

I'd recommend running the ground to the cigarette lighter ground. That's the way mine is...and it works great.

14 gauge is way too small for a 15' length. Use 12 or even 10 gauge. The smaller the wire, the more heat is produced which could cause problems later. I don't know if your switch is big enough either. Try Radio Shack's SPST 12VDC@30A switch (Cat. No. 275-712). But first, take Spud42 and Old El Paso's advice and run a second line up to the cigarette lighter. If that doesn't work, then take my advice.
