No brake lights or running lights

[Jhughes08]

I have a carpenter body bus with a 3800 I yet atonal body. I have no brake lights and no running lights in the back. Has anyone else come across this problem and a solution?

[Jhughes08]

I have running lights on the sides and front

I lost mine and it was a multi-pin plug in the elec. door by the driver, came unplugged.

Ok. Do the front and back lights come out separately

the Body to chassis connector is notorious for coming loose.. im assuming you have lights in the front? if not, then check the fuses up front on the dash just to the left of the glove box cubby...

one of the body to chassis connectors is behind the kick panel on the left in front of the driver heater console...

I just ended up jumping from the running light wire for te over head clearance in the back and ran them down to the back lights. The brakes ended up being the switch. That being said why are there two brake light switches?

[cadillackid]

I just looked that up in the wiring diagrams and it literally shows that both switches are in parallel.. basically they assume one or the other will trip... at least electrically thats how its set up... id have to look at the air valve to see if theres any reason mechanically...

on hydraulic brakes theres only one switch..

Mine has hydrolic brakes and two switches. I'll replace the lower one, the pin isn't coming out anymore and see if that works

Check fuses and bulbs before you get too far chasing harnesses. I had a bus that had blew a fuse because of a shorted filiment in a bulb. Seriously.
