Still struggling with this. Everytime I hit the signals to go left or right all 4 flashers come on. They turn off when I hit the signal button a second time. If I flip the hazards switch on and off, then the right side starts flashing on its own without me hitting the switch. Strange.
Horn Fuse is ok.
The signals are flashing fine so I do not think it is a ground issue. For some reason hitting the signal switch on both sides just activates the four way flashers. Im tempting to rewire the signals into a more simple circuit. Like my R90 which has gone 40 years with no signal issues...
