EC 30 Controller

My wife and I recently committed to the full time life. We are the proud owners of a 2014 Adventurer 37F. I have been attempting to set my gen set to Autorun with the EC 30 module. I can not get past the "Safety - ignition on-off" setting. I've turned the ignition on and off, both starting the engine and not starting the engine. I've run through the setup info and tests and can't get anywhere. Is there a secret I'm not finding . Do I have to find a place to do service. I'm in a place right now that would afford the time if I could get in before mid July when I have commitments to be places.


Any suggestions.
Thanks

Did Auto on ever work? Does the gen work?


Parking brake on, ignition off, MH in Park, press AUTO GEN to get to Auto then ENTER. Works great on ours.


I would all Cummins(in Elkhart) and talk to them. I think the manual might have a trouble shooting flow chart. I also would go to a Cummins dealer rather than an RV place or call a mobile mechanic.

Auto on has never worked for me. Albeit we've only had her a few weeks. Parking brake on, ignition off, MH in Park. Press Auto Gen Readout = Ignition on off. Per the manual this is a safety feature preventing auto run until you have reset the safety (every 30 days) by following the prompt, ignition on off.

The gen has worked though Correct?



I would just give Cummins in Elkhart a call, they are very good about diagnosing over the phone.

Suggest you download the installation manual. The safety lead receives an electrical signal from "somewhere" - wherever it was connected to. I installed one in a Class C and rnded up connecting it to the side marker light controlled by the light switch. The wiring diagram will tell you what lead on the harness at the rear that the safety should be connected. Yours might never have been connected, become disconnected, or still connected and you can get the circuit off the winn wiring and identify it in the cabling section of the wiring diagrams. Once you get that info, you will know what the unit is expecting to receive. It is really quite simple to determine. Good luck

Do you even get the 'Auto on' in the window? Remember, if 'Ignition on-off' is flashing you have not hit Enter.

Might be some info on this issue over here. There's a link within this one that also suggests a fix/resolution. Good luck with it.

I had a similar problem with my EC30 that I installed. I found a pin on the connector on the back of the unit had spread and didn't make the correct connection. I replaced the bad connector pin and it works fine. 2015 Itasca Sonova 35G

Temporarily. I went to the Cummins service center in Richmond VA and they reset the “safety” by putting power to the safety ports in the wiring harness at the controller.

Power is not being provided to the controller when any of the safety reset procedures are performed according to the manual. The told me I should bring it to the original dealer as the would be the only ones to know where the other end of the safety circuit is wired. $220 later and I’m still looking at the same problem in 30 days. Until then I have auto run

Winnebgo has all their diagrams online so you shoud be able to trace this yourself. If not, give Winnebago a call and talk to them. Don't go back to a dealer, that is all they are going to do.

It is a 10 minute job to fix it yourself.
Download the Cummin Onan EC-30 installation and operations manual and read the section on the safety input.
Fix it by removing the magnetic overlay on the front of the unit using a knife to get under it. Remove the two screws and pull the unit off the wall and lift it off. Disconnect the unit from the rear 16 pin wiring harness. Check you manual for pin polarities - pins 15 and 16 are the safety input. Hook up one of the light switches to the positive input and the other to a ground - all on the harness.
You are done! Reverse to reassemble.
The positive voltage from the light switch is not used by the unit beyond "sensing it" but resets the safety function whenever you turn the light on.
Hard to believe but it is that simple. MAKE SURE the connections to 15 and 16 are secure - either soldered or preferably with with crimp wire connectors. Dont use the twist connectors.
You are wasting your time calling Winnebago as once you have downloaded the manual, you will have the same info that Winn has.
