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
