Bus starting problem SOLVED

[Danss]

MY problem with starting the bus from the front was believe it or not, a bad run start switch in the rear which was the only place I could start the engine. Switch was $21.00 plus 2 hours labor to run it down. I would have never believed that the very switch I was using to start the engine was causing the problem As we all know the buses are a work in progress! Thanks to everyone for the help. Dan

Great news!

Happy days Dan,
glad it all turned out so inexpensive.
Your no start problem goes to show that when trying to run down a problem, you can't rule anything out until proven otherwise.

You mean the selector switch that chooses between front or rear start?

[Danss]

Jon, it was the switch that has 3 positions. Down position says normal, middle position says off, up position says something in French and it has to be in the up position to crank from the rear by pushing the starter button just below . It is a Toggle switch. Hope this clarifies location. Dan

It's always interesting to hear what solves the problem. When looking back at all the suggested advice, I''m wondering why the rear switch was not tested. Are we missing an opportunity here. Shouldn't there be a logical step by step method of problem solving an electrical problem? What did the mechanic do that all of us combined did not do or think of doing. Are we missing the boat on helping one another.

We were close. If you remember Gary, Dan suggested he had a dumb question about double checking that switches position.

If that ever happens again we gotta good place to look now.

Chaloupka should have suggested that, he's the culprit.

Dan....that is great news and as Joe said we were almost there. I think I posted to check for power at wire 84 at that switch while someone was turning the key.

If power was there, but not getting to the start solenoid it had to be R4 relay or the switch. Your bus repair guys did good.

So, Dan. I may have missed it in an earlier thread, but where did you take the bus for repair? Sounds like the guy has his "stuff" together and it's always good to know where these folks are.

Yea ,Yea, blame it on me. It was in fact the Murphy's law within the Peter Principle that did it through the (POG) computer diagnostics (garbage in garbage out)
