Hi all, hope everyone had a great Holiday Season. Back with my usual issues, electrics. I keep blowing the #4 fuse whenever I use my turnsignals. It does not blow right away, but eventually the fuse will blow. Since the circuit shares the fan relay, I tried to isolate the problem. I resorted to hand signals for my turns. ( have not done that since my 1966 Ducati). No more blown fuses. I'm hopeless with electrics, so anyone have any suggestions on how to hunt this down or anyone else experience this problem? I have one of the older cars, chasis 188. Thanks.
