Where do I look to start tracing electrical issues?
my electric fans were not working so i thought as a temporary fix id install a toggle switch... i used the dome light fuse as my power supply. once installed turned the key on and melted the hot and ground wires running back to the switch as well as the dome fuse.. which was a twenty amp. fast forward tried to start car after replacing the fuse no indicator lights and no power to fuses. only light i get is airbag indicator. checked battery tested good, have been checking fuses found two others that were no good replaced but still the same issue. but in fact i got some power back when i replaced a tan fuse with no amperage stamp,lights,key alert dome lights, etc. but still no indictors still won't start or crank nothing any ideas would be greatly appreciated.
