couple of questions please,

this may be a dumb question,but how do the house batteries charge on my1983 sportscoach. do they charge when the coach or generator is running or only while the shore line is plugged in. i do not have a 50 amp plug run out to my mh. yet, i have only had it for two weeks, also can anyone tell me where to turn on the water to the shower and bathroom sink.

My shower and sink are active when hooked to city water, or storage tank..
Your batteries should charge while the engine is running or with your gen.
Does your RV require a 50 amp plug in? Can't imagine 50 amps.on a 1983

There should be a 30 amp cord in a compartment accessable from the outside somewhere. If it is like my '87 Itasca it is plugged into a socket on the coach for generator use, or unplug from coach and plug it into shore power.
There should be a hose fitting on the outside of the coach or in a small compartment to hook city water too. There should also be a connection to fill an on-board tank that has a 12v water pump in-line to supply water to the coach when not hooked up to city water.
look for a switch marked pump on a panel, probably near the kitchen sink.

It would seem someone has done some revamping of the coaches systems.
It is unusual for 1980's Class C coach to be 50 amp..so someone has upgraded the electrical system. If it were me, I would study the system and make up wiring diagrams etc. for my own edification.

It is unusual for the bathroom shower/sink water to have an independant shutoff..so is likely another re-do. All one can advise is to get a flashlight and trace all lines from input and see what you find.

Good luck!

Also sometimes there is a switch to turn on a solenoid to charge the coach batteries from the engine alternator. Some rigs have an isolator that is hooked up in line to charge the coach batteries.
Use a voltmeter on the coach batteries when the engine is off and get the reading, then start the engine and see if the voltage increases. If not look for a switch.

You and me a 55,000 others find this site helpful and encouraging.

On a tangent...there often are posts from folks asking if the RV sales guy should be trusted/believed...and the often answer is "not really". Yours is aother case in point. Obvious there are exceptions to the rule...but generally sales folks are sales folks and nothing more. As the great American Ronald Reagan said "Trust but verify"

You can pick up one of these

Amazon.com: Conntek 14101 RV Adapter 15 Amp Male Plug To 30 Amp RV Female Connector: Patio, Lawn & Garden

online, at WalMart or any RV supply store and you should be fine for shore power at home if you don't have a 30 amp outlet.

Note: I'm not endorsing Amazon for this, it was just the first link that I found with a pic.

if you use the 15 amp adapter you probably will not be able to run your a/c as this will overload the circuit or burn out the a/c compressor from low voltage.
Will be fine to run the lights and charge the batteries.

My A/C runs fine using this style adapter on a 15 amp breaker from the house. I'm not able to run the microwave and A/C at the same time. I'm not pretending to be an electrical "expert" here . . . but I don't think I'm risking burning out the compressor . . . why are you saying that the voltage is low???
