I currently use an inverter to power my car mp3 player. In my old car i had the inverter mounted under the drivers seat and ran a 120v power lead to the computer in the boot (switched on manually). This worked fine. I now have a new car and decided to mount the inverter in the boot with the computer. I purchased a relay with a 30amp fuse on it. I installed a switch that ran off the ACC line to the relay (pin 85) and connected a ground (pin 86) to it also. I connected 10guage power wire from battery (fused at 35amp) to the power input (pin 30) and the other pin 87 to the positive input on the inverter. I connected the negative input on the inverter to chassis. The problem is as soon as the relay is switched on the fuse blows on the relay. Is this because the relay is fused at 30amp while there are 35 amp fuses in the inverter and at the battery connection? The fuse blows when the inverter circuit is connected but before it is switched on at the switch on the inverter. I have not tried higher rated fuses in the relay because i didnt want to risk blowing my inverter. There are no obvious short circuits that i can see. Any help would be appriated as to what i am doing wrong. Cheers
