Here is a video on some issues I had with my Allison MD3060 WTECII control module. The unit wouldnt allow me to start the RV which is a 1994 Holiday Rambler Endeavor. This is a very common issue with these aging units, as it is now 27 yrs old. I had no issues up till now, so it is very sudden when it does happen. I was able to find a company that rebuilds these control modules, and now in the process of having it repaied. The web site for the company is http://www.transmissioninstruments.com
The Guys name is John that runs the company, and is very personable on the phone. I called him and he helped me run through the trouble shooting process. Now he also has some technical troubleshooting procedures on his web page for the more advanced electrical person. I Do HVAC for a living and also amateur Radio, so electronics are my thing and it was easy for me. I hope this video will help others in the future with the same issues I had.
Enjoy!!!
