'92 breakaway with 5.9 cummins.

Once in a while when I turn on the turn signal the engine dies. Have replace the key switch and the turn signal relay. Both seemed to help or maybe just luck. I know what happens is the circuit shorts out. Turning the key off and then back on resets and usually good to go. I have started to turn the signals on as soon as the engine starts. If it keeps running I will have no further problems.

Having spent years as a electronic tech I know that these intermitant problems can be a nite mare. However, if any of you have had this problem would like to know what you found.

Hi Gary,my 91-breakaway does the same thing,I find when she is cold and I activate the turn signal she dies.When she is warm only sometimes cuts out.And one time I left the drivers seat and walked to the entrance,about 5ft.she died.I'm really at a loss about it???Its really got me bummed out.Just searching on here to find a solution..Were you able to figure yours out?Any ideas would be much appreciated,thanks-jamie

Fixed it but don't remember exactly. I know I changed the ignition switch, but that didn't do it. I know I changed the master relay in the electrical panel below the driver side and I think that fixed it. This is the relay that looks like a ford starter relay, but is rated for constant duty.
