The amber warning lights in the eight light system won't come on. I can't find a flasher unit. If I leave the door open and work the amber light button the reds won't come on Like other buses. So where would I start?
Is this a conventional or a transit bus? C2's use a magnetic sensor hose clamped to the air cylinder that can come loose and needs to be readjusted. We have no electric doors, so I cant help you there. Transit buses have a module 1000-2000 like the old yellow ones but long and black. The red's switch often goes bad in the transits. The ones with air doors also use the magnetic switch for door position.
flasher unit is located in outside electrical compartment rearmost corner, it's black 2" wide 4" or so long connections out of the bottom. most likely buried under some wiring.
