intermittent turn signals and hazard flasher 1981 MCI 9

[RickB]

Hey all,
Before I go diving into manuals and spending the day trying to fix this, I thought I would give the combined knowledge of my fellow bussers a chance at diagnosis. My turn signals and emergency flashers started acting up about a month ago. They are intermittent but they aren't working about 90% of the time. When they stop working they don't do anything, no turn lamps come and stay on, no flash, no nothing.I am imagining a relay or a flasher but I am not sure about location and I certainly don't know the wiring of my bus as well as most of you guys.
I await your suggestions with a screwdriver, a blowtorch and a steaming hot cup of java...

  Warning to much java in testing circuits can cause smoke to escape

Nick had a simular problem about a year ago (lots of discussion on that thread)

Control panel is on the outside under the drivers window........ (at least on an 8 it is)

  The flasher does go bad.........I would check to see if the flasher is getting juice first

Hope this helps

I would start with the circut breaker in the elcetrical panel under the window. Breakers have been known to go bad and can also be intermittently bad.  There should be a schematic on the door.  If not it may be breaker #45, next I would check the relay.  You will not need a torch or sledgehammer for this.  HTH  Jim

Rick; check all the lights when it is working to make certain that there is not a short in one causing the flasher to over heat fwiw if you add extra lights to the circuit it will cause that

Try a new flasher.

Up under the dash in the corner near your left knee, it's under there somewhere, maybe in the mount, or dangling. It can't be far, it has to be near so you hear the clicking.

Good to have a spare anyway. In those days, most good driver's carried one in their bag.

Don't forget...24 volts!

happy coaching!
