I recently purchased a 1986 PT38 (8V92 Detroit) from a reputable RV dealer in Orange County, CA. I thought all was working ok, but have found a few quirks that I haven't been able to remedy...
#1: The little blue "on" indicator dash wont go off on rear landing lights or rear back up lights, and the actual lights don't turn on (sealed bulb out maybe?)
#2: When hooked up to shore water, I don't get shore water...only tank water w/pump.
#3: Do I have to take apart the docking light housings to get to the bulbs?
#4: My refer only cools down to 43 degrees...AC/DC or gas...anything I can do? The temp control is turned to coldest setting.
#5: The engine compartment squirrel cage blower went out...the bearing pin broke off the blower thingie. I've called just about everyplace, BB included, and no help or suggestions. I've been told that the engine fan/blower really isn't necessary...am I taking a chance of hurting anything by not having one?

I have a few more questions, but I'll wait 'til next time. So far, even with the little quirks, I love my BB! What a nice machine!

Thanks

Here are some guess answers to your questions:

#1 - rear landing lights and back up lights have been turned on by the security light switch in the bedroom - bulbs are probably burned out from continuous operation - turn off security light switch before fooling with the bulbs.
#2 - you wont get shore water unless your "Tank Fill" switch in the utility bay is turned off. I cannot understand why you have not seen water running from the fresh water tank overflow if the "Tank Fill" switch has been left on. Water has to get into the tank somehow, and the Sporlan valve (solenoid) operated by the "Tank Fill" switch cannot have failed in both the open and closed positions simultaneously.
#3 - probably - BB has different lights for various years.
#4 - call Dometic at 800/544-4881, but you probably need a new refrigerator.
#5 - the squirrel cage blower in the engine compartment was manufactured in England and cost a princely sum when new. From the start the fans had bearing problems and ran down the batteries when stopped without shore power. Most owners I know have abandoned fan repairs and operation. You can add a pair of electric radiator fans to the battery access door if you like.
