 Huh My 1985 Eagle Model 10 left side blinkers are not working correctly.The front blinkers work left and right,front to back, but when it acts up only passanger side works front and back. If the bus has been sitting overnight the blinkers will work correct for 5 to 6 times switching right to left. The hazzard lights are the same. A few tries on and off and then only passanger side works. I have switched relays still same malfunction.  I am scratching my head on this......any advise will be appreciated. I hope this makes sense

I would check the bulbs first, then grounds, then the lead wire for voltage with a meter.

Have you changed any of your bulbs to LED's.  Those blinker relays work by power draw and the LED's are so efficient that they don't work properly.  You have to add a resister or change the relay to get them to work 100%.

      Yes, Scott, you're right here, but I think you should be using the term "flasher unit".  Not that it matters to our conversation here (I think everybody knows what you mean), but if he goes into NAPA and asks for a "relay" the guy may give him a different part than if he asks for a "flasher unit".

The new electronic flashers units are self adjusting to a load best 20 bucks you can spend,his unit is electronic and they go bad they are pricey for his model so I would change over to the new smaller electronic flasher.

If his bus has been converted they may have moved his flasher sometimes they are hard to locate when people move the units and install it behind a wall lol BTDT

Hi, my still original flasher relays, didn't function when I first got the MCI, they are old fashioned mechanical relays enclosed in a see thru tube like case, from the 1960's era, mounted in the engine compartment. By pulling the relays, cleaning the contact points, and slightly bending the contact blades, for a more secure hold, and then excercising the inner contacts for a few weeks, just by using them frequently, thes older era electronics have come back to life, and work fine, my history in electronics, especially the old engineers who always told me to excersice the equipment, before throwing it way, still holds true, but like Clifford says, the new ones can handle loads not even thought of back in 1966, my Dad always used to say checkout your grounds first thing, next item up for me is to locate a hi beam foot switch, which is rusted, not sure if I need a 24 volt for this or if a generic will do,  lvmci...

Check all your bulbs to see if any are 12 VDC if your system is 24VDC.  I had a problem with mine--worked with the engine off, but when the engine was on they wouldn't flash!

Apparently, since I changed my rear lights to LED's, putting one 12 VDC bulb in any other position draws too much current(inrush), and kicks out the circuit breaker.  I scratched my head for days!

Thanks for the info on things to check. I haven't been ignoring all the posts. My work shift is not allowing me to work on the bus. I'm hopeing that friday I will be able to work on her. All of this happened when I pushed in the hazzard switch on the steering column in stead of the dash. The red tab of hazzard switch on column was borken off but I pushed it in anyway. I drilled a small hole in the cinter of switch screwed in a screw pulled out switch, but still have the problem. Do any of you think that this has anything to do with my problem. All lights worked correctly beffore I pushed in switch?

    Just a WAIG, but if I had to bet some of what little money on something, I'd bet that that switch is your problem.  It's almost as sure as "what was the last thing you fixed"!

 ??There has to be a grounding problem. I've replaced all lights, cleaned all grounding points and wires on blinker lights. All blinkers worked for three days the started acting up. When the left side blinkers are not working I can push on the top left corner of fuze panel and all of a sudden everything works. I haven't quite found the smoking gun. I am closer to the qulprit.
