I was wiring up a led lightbar and blew something. all fuses are good including main fuse. engine will turn over but not start. dash instrument panel is dead. here is how this happened. I was going to wire my 3 gang switch board direct to accessory plug then to 12" lightbar. well, to rk and they had lightbar wire harness for $1.29. figured I might use this with my 3 gang switch panel I got. thought a relay would be nice too. switch on wire harness was cheap had it all working ok using 1 wire off harness switch to 3 gang switch.and relay powered by switch. I decided to hook relay direct to battery and wire from harness switch to accessory plug lit switch. it worked for about 20 seconds then nothing. no I cant figure out what I blew up. dumb me. need help please
