turn signal flasher problem

Unread post by steve1973 » February 4th, 2018, 11:52 pm

Hello all,

I posted this over on the G503 also.

I'm working on my Dad's M151A1 again. The turn signals stopped working. I traced it back to the flasher unit. I unplugged the old one with plastic housing and plugged in the new one with a metal housing and left it hanging. Turn signals worked. I mounted the new flasher back in its original spot and tried it again. It tripped the circuit breaker. I unbolted it and left it hanging and it worked fine again. I remounted it and it tripped the circuit breaker again. My thought is that the relay is defective with an internal short to the metal housing. What do you all think? Should I try and get an original plastic housing one or another new style.

The one on the left is the original one from the jeep. The one on the right is the new replacement that is tripping the circuit breaker.

The harness is brand new from Vintage Wiring of Maine and the ground wire is properly grounded. The new flasher unit was new from VWM also.

Thanks in advance for your help.
