I just bought an 81 coupe and the turn signals don't work. I sent off and bought a shop manual and followed their direction, I did not have back up lights so I replaced the fuse, turned on left flasher, worked for 5 flashes and the fuse blew, I replaced fuse and tried right flasher and t 5 flashes later fuse blew, replaced fuse and left ignition off, nothing happened, turned on ignition and a minute later fuse blew (without using turn signal), replaced fuse and removed flasher unit, turned on ignition and a minute later fuse blew. I'm guessing next step is to somehow disconnect back up lights from circuit and try a new fuse... could use some suggestions. Thanks! Tom
