Here's an issue I have now. I have a good friend who is using my 2004 Fleetwood Discovery Cat DP for a family vacation.
(That's not the real issue haha)
What has happened is that the alternator is going out (based on the symptoms he's described for me). I had an issue just like this when I bought the motorhome. I fired the generator up and the chassis batteries were charged while I was driving until I got home and then I changed the alternator. Luckily I was only about 150 miles from home when the alternator went bad. But luckily the generator saved us.
Now, my friend ran the generator and it isn't charging the chassis batteries. So much to the point that the motorhome's transmission selector wouldn't work while parked. The chassis batteries read 11.00 volts per the gauge on the control panel above the passenger seat. The house batteries are 6 months old and are charged fully at this point. I've read about a battery bridging solenoid possibly being bad, but this was only in general terms and descriptions. I did not find anything specific to my model. And the battery switch to jump the house and chassis batteries did not work either. It would run power up the gauges and seemed like it was working, but when he went to crank...nothing.
He's going to Freightliner tomorrow but that's only going to get the alternator replaced.
I had just recently last month had the motorhome out with the family and had no issues like this. Of course almost every time I lend something out, something weird happens.
If anyone has any ideas, please share. Thanks!
