1993 GMC G3500 Vandura based school bus
I just got this former school bus. Overall it's in great shape, but it has electrical issues - particularly concerning the school bus-framed electricals. I know that when a school bus is decommissioned, they remove a number of the school bus features and repaint it.
The electrical panels above the visor, in the school bus body. The other side of the squarish unit shows the image of a school bus with led indicators to show what lights are on. This never worked. The longer set of switches has only three active switches installed "Dome" (which works), "Master Warning" (does nothing) and "Recycle) (does nothing).
You can also see a panel which is exposed when I took a plate off near the top of the bus.
There are tons of wires up there with little clue as to which ones go where. There is no schematic I can find. The major things I MUST accomplish are:
-Get the rear brake lights working. No idea why they aren't
-Get the rear turn signals working. Front turn signals work fine
-Get the hazard lights working. When I pull the knob, I get one flash and then they just go out.
-Get the electricity running to the rear heater/a/c unit
The company that made the bus body is out of business, so I'm SOL on the schematics. I need to get the first three things working just to get it inspected.
Thanks in advance for your help.
have the same problem?
