Vanner Equalizer and Prevost Gold Pass
On last Saturday at 1:15 pm I had reached an impass on solving the issues of what was perceived to be dead batteries after the replacement of the Vanner Monitor and four new engine batteries. The hi-lo signal was gone but the coach was absolutely dead. It was not the batteries…. it was primarily a loose nut on the ground of the starter and it cranked immediately after tightening helped by a prayer…. What did not help was when I loosened up the 24 V connection on the starter and hit the side of the engine with the handle of the wrench which lit up the whole side of the warehouse…I admit my shortcomings…. The point I would like to make is that I called the Prevost national line and had a mechanic on the line within two minutes. He had a schematic of my coach and was super, super helpful. He walked me through every step of checking the system and even taught me how to use my voltmeter correctly. When I got the coach started, I called him back and we had a great conversation… super service…
From this I gained the insight that a non-response from the ignition may not be the batteries but a loose connection to the starter. I just did not take my analysis that far. I have started the coach nine times and will continue through a cycle of about twenty to see if the solenoid has a hot spot on it.
My thanks to Prevost…what a great service….thought those of you reading this might be interested.

Good deal Pres, glad you’re back in action. Nice to hear the Prevost hot line works, you’re the second person in a month that I know of that’s had great service and results.
Thanks for the post…

Actually there are a significant number of things that can contribute to having nothing happen when you turn the key some of which you can work around (such as a bad selector switch at the rear box), some of which you can do some parts swapping like a starter relay in the rear box, or any number of other minor and not so minor things.
It is great to have someone who can talk you through eliminating or isolating problems because unless you work on these coaches all the time it is almost impossible to zero in on the real problem.
So Prez, did you say you had a screw loose???????
Just teasing.

Just because I wanted to post something, but have little to offer, I will tell you about one more thing that could keep the bus from turning over when you turn the key.
I spent some time on the phone with Troy while I was staying at Dizzy World with the above problems. I almost stumped him. Checked a lot of stuff, to no avail. It turns out that I somehow triggered the alarm on the bus, which has an ignition kill. Just one more thing to keep in mind.
