Title: 102a3 lights/electrical advice needed
Post by: philiptompkjns on November 20, 2009, 10:59:36 AM
Hey there, so I got an 102a3 last week, most of the "bus stuff" works but  the  headlights are one exception.
I do have the shop manual for that bus and  from looking at the electrical diagram for  the headlights it looked like  the power for  them came  from "in between the  two batteries to get 12v. I look a look in the  electrical box and  there  is only one fuse, a 10 amp I think, and  it is blown (could not really see what it was for though). So looking in the  battery compartment  there  are two cables with connectors  on the ends that  look like they used to be bolted to the  battery  terminal, which made sense because  the last owner changed the  batteries  at some  point. Does anyone know which of these cables are which? and how  exactly they  should be hooked up? one of the cables goes to a 10amp breaker in the battery  compartment, the other does not.   Is one a positive and one a negative?

One more thing:
If the left blinker works, and with the emergency flashers  on they all flash, but the left blinker does not work.... that is probably a faulty switch right?
If the right flasher were out the emergency flashers would not work on the right side, right?

Well, thanks for reading... I'm sure I have a million questions but those are a few that I thought you guys could really help me out with.

Hi Phil,

Your almost right.. Those cables most likely went to a inverter to power the TV systems inside your bus.

Yes, one is + and 1 is -  12v dc.

Your second question sounds like someone installed the wrong bulbs in the turn signals.

Hope this helps
