OK, do you have a general idea of where the solenoids might be located. I have the aux battery switch on the left side of the dash, this controls battery power to the house side of the rv. So when I toggle this switch back and forth the solenoids should be making a clicking sound if I understand what you are saying. The RV is up where i keep it for football games, I will be there this friday and check out what you have suggested. Thanks once again for all your help, if I can get this done myself and save some money that would be great, seeing how I just spent a ton on getting the exhaust manifolds replaced three weeks ago,
