Thanks again, I wasn't able to do anything on the coach today, maybe tomorrow. I did find a drawing of the plugs and what approximate readings should be so I'll give it a try with voltmeter. The drawing I have is on a Spartan Chassis and I'm guessing the Medallion is wired the same as my HR gauges. So anyway the saga continues.

Thank you for your offer I soldered the three wires on the off on switch and that did it just old I guess

Hi Myron!

I have a 2008 Diplomat SFT and would love for you to send the files you have on various aspects of your coach. I bought from the original owner a few years back and he did not do any of his own maintenance or repairs. I have done many many upgrades and repairs and I really enjoy it.....most of the time. Much thanks to this forum for helping me find and troubleshoot many issues.

I don't see that I have a BIRD system but I do have the trombetta with the white and purple wire that was bad when I bought the coach. After replacing it it worked fine for 1 1/2 years and now it isn't charging off the alternator again. It seems intermittent and when its not working, I have no DC power to either the purple or white wire even though I know the chassis batteries are full charged.

Thank you so much and my email is tgidoug@msn.com
