I need some help understanding my sled's electrical system. I'm trying to wire my GPS directly to the sled's 12V system. I bought a 12V female accessory adapter, found a positive and a ground among the instrument cluster and wired it in. The accessory adapter that came with it only has a .5 amp fuse which pops immediately, but the same fuse holds up fine in my truck. I figured that 12V was 12V, obviously the amps are regulated down somehow. So, ah, what do I do?
