Dick Roberts Posted January 13 Share Posted January 13 Hello, I'm new to the site and to RV life. I'm in the process of buying a 99 Diplomat 38A DP. I went and looked at it last week. The first thing the owner showed me was a 3 week old repair bill, from reputable dealer, for several thousand dollars. I don't remember details, my impression was a general check and service after sitting. At that time, everything worked. 3 weeks later when I get there, the house batteries are dead and the generator won't start. Shore power not available. The chassis batteries appeared fine, and the coach started with no issues. The owner was supposed to get the house batteries charged before I return to complete the buy this coming Tuesday. Spoke with him yesterday, and he hasn't and won't charge them. He's afraid he'll hook something wrong and cause damage.\ I've been researching this and other forum sites to glean as much info as I can on this issue. There does not appear to be a simple yes or no answer to my question. I know, it's taking me a while to get to the question. Do all y'all think driving the MH a 100 miles would allow the alternator to trickle charge the house batteries enough to crank the generator which would then fully charge the house batteries? Or jump the gen off a 12v car battery? I'd prefer to get the gen started before I buy it. Without the gen, or house batteries, or shore power, nothing works. I can't check any of the systems. Of course, y'all didn't need me to state the obvious. I think the cause of the bat drain was a new gizmo they installed at that 3 week ago service. Seems the speedometer needle has fallen off of the shaft it should be on, and is lying in the bottom of the dial. The service center installed a electronic speedo that uses heads up tech to display speed on the windshield. Connects via USB cable that runs under the dash somewhere. While standing by the door, I noticed it was making a slight noise. I pulled the usb cable and the noise stopped. I'm guessing (hoping) the owner left it on when he returned from the service trip and that drained the house batteries after running for 3 weeks. Sorry for the long post. I tend to ramble some/most times. Thanks in advance for any thoughts. Link to comment Share on other sites More sharing options...
