Any suggestions to point me in the right direction on this vexing situation? Here are the facts:
(1) engine has been running great nearly every day for several months ... started every time in about 1/4 turn with pre-heating
(2) aired up the bus with aux compressor as I normally do, bags were up and bus was level
(3) turned the key ... zilch ...
(4) tried the rear start switch and button ... zilch
(5) not a groan or any indication that the starter was trying to turn
(6) batteries are new (four months ago), and all cables are clean, tight and connections are well protected with Vaseline
(7) voltmeter tells me there is nearly 25 volts across the four batteries
batteries have always been connected to a battery minder that is claimed to keep them "stirred up"
(9) bus was properly shut down in neutral (Allison 5 speed), and air brake applied, tag axle down
(10) to be sure there is air in the system in case the aux compressor somehow did not get air to the controls in the engine compartment, I used an air hose to fill the rear air tank. It seemed to be up, but just in case I did it manually.
Starter solenoid problem? If so how do I test it or better yet how to jump around it without frying myself or something else of value?
I'm writting this from an RV park in Alabama where there is no panic to get the problem cured but sooner or later, I think my wife would like to get on the road again.
We phoned the road service insurance people this morning and they promptly sent out a little guy in a pick-up with a tiny 12v battery to "jump start" the bus. Sigh ... Even after my careful explanation of the situation and the fact that the bus is 24v. The perplexed road service guy was kind enough to give me a phone number of a fellow who might know something about 8V92's. This is comforting ... especially the "might" part.
Such is the tale of bus ownership, I guess.
