There was a large placard on the back door showing chassis charging system and specified 12 volt with the four chassis batteries outlines. That turned out to be a 24 volt unit, belt driven.

the large alternator is connected to a 12 volt regulator mounted on the rear bulkhead. That's the device that keeps the 12 volts steady for the house systems. Right now it is keeping the 24 volt alternator from toasting everything down stream. I'm not running engine anymore than absolutely necessary to get the unit back to Fla Detroit as I dont want to cook that regulator.

Fla Detroit messed up in not checking part numbers closer. It turns out the Tampa branch had been setting on this alternator for some time and were happy to ship it out. Looks like Ft. Pierce branch will now be the owner.
Mike,

I own a 1995 XLV, Country Coach. After reading of the converter swapping the Prevost alternator functions, I went out and traced the wiring on my unit. Sure enough, the smaller alternator (Delco) mounted in a CC supplied housing (the coach AC in mounted on the same bracket, above) is connected to the engine starter (Series 60). What a surprise!

I recently purchased a new Elreg replacement for what I thought was the original Prevost service (Not installed yet.). Humm.....

My alternator case is leaking oil. I replaced the front seal, but did not resolve all the leaks. Mine appears to be leaking where the o'rings seal the main case. I guess that the rubber o'rings failed over the years.

I would very interested in finding our what is the modification, if any, needed to the Prevost alternator to suit the 12 volt service. I wonder if the installed regulator is designed to reduce the 24 volt output to 12 volt service for recharging the house batteries?

I would be very interested in what you find out.

What a great comment on these Country Coach systems. Another instance where keeping up with the comments on the POG forum has lead to learning more of these complex machines.

Thanks,

Hector
