I went to the coach (1998 Marquis, C-12, 10KW gen) in storage today for the first time in perhaps 6 weeks, maybe more.   (Health and medical insurance issues prevented my from going sooner).  My intent was to run the generator to charge the house batteries.  I always turn the main battery switches to off when I put it into storage.  On arrival today, I turned the switches to ON and primed the generator for about 1 1/2 minutes.  I noticed that I could not hear the fuel pump priming the generator.  Tried to start the generator, nothing.  I held the battery combine switch, still nothing.  I went outside and tried to start it with the switch on the generator, still nothing.  I was able to start the coach engine just fine.  Seems that there is no 12 volts to the generator.  I was not dressed appropriately to climb underneath to check the incoming voltage to the generator, but will do that tomorrow when I have more daylight available.  Meanwhile, perhaps someone on the forum can tell me if there is a relay or something else that provides the 12 volts to the generator??  Thanks in advance for your help!!
