Generator keeps auto starting ..

Go to the Genset. Look at the cable connections and you will find the REMOTE start wire harness. Disconnect this harness. You can still start the APU at the Genset switch ON the Genset. IF the Genset only starts in transit, you probably have a remote start harness pinched somewhere and while driving the movement of the motorhome is completing the GROUND signal that starts a Genset when the wire gets pinched. By disconnecting you verify that the Genset will not start again until the problem is found. IF it starts after you disconnect the remote harness at the Genset, you have an internal fault at the Genset. The Auto Start feature uses the remote harness to start the Genset, so disconnecting at the Genset will disable this feature. MOST Motorhomes that have Auto Gens start, that feature is NOT enabled from the factory but by the dealership Technicians when delivering the motorhome to you during the walk thru. If NOT addressed at the walk thru, the Genset start is never enabled. Unless optioned, I doubt a Southwind comes with the Auto Genset system. The 2015 Southwind standards and options show NO Auto genset option at all. I doubt you have the option. You have a wiring malfunction causing your problem. Doug
