My father and I spent the afternoon poring over the wiring diagrams of my bus to diagnose the short in my taillight wiring. Dinas have the craziest wiring schemes I have ever seen! Half of the marker lights and the front parking lights are on one circuit and the other marker lights and taillights are another another circuit controlled by the same switch.
Anyhow, we finally figured out how to disconnect various parts of the circuit with the issue and found the problem. One of the marker lights was shorted out! Pretty simple fix. We can't see what is wrong with the marker light other than it was packed full of debris between the bus and the housing. There was also a inline splice behind the light because apparently the light was replaced once.
Nice to at least have full working lights again.
Congrats! If only every fix were so simple and inexpensive. Way to Go ;D ;D
Good For you & Dad,
Looks like you have your brake light problems now behind you.....
