A/C & Generator stopped working

I thought I would post this in the General Discussion forum because I am not getting much feedback from the National Owner's forum.

I have an '05 Dolphin LX, Workhorse with 8.1 gas engine.

I went camping this last weekend. It was very cold (even froze the drinking water hose).

When leaving the park, I was in a hurry and I made the mistake of not flipping the 50 amp breaker before disconnecting. Now have no A/C nor will the generator start.

When I say no A/C, I mean that even the thermostats does not display anything at all, and there is no response regardless if I move the switch to LP Gas or electric.

The generator was recently fully serviced and ran fine the day before going camping. It is getting fuel and when I push the starter switch it turns over, but there appears to be no spark.

I believe that my issue is related to a possible power surge that made through a breaker or a fuse tripped, or something. I looked at all the breakers that I am aware of on the inside panel, on the generator, and on the inverter, but did not find any that are flipped.

Regardless, now I am plugged in at home to a 50 amp box.

All the other electrical is working fine. All the plugs, the convection oven, the TV's, water heater, all lights, the refrigerator, etc.

I thought I would reach out to my iRV2 friends to see if anyone had any thoughts about what else I may try.

Please provide your feedback.

Thanks,
Ted

Your thermostats are 12 v. Since other 12 v systems are working (water heater, refrigerator, interior lights) I don't think your house batteries or solenoids are at fault. Since the generator turns over but doesn't start, it also is getting 12 v. Check for spark on the generator. Not sure that unplugging shore cord while powered should cause generator or thermostat to not work, sounds like you've got more than one problem, but not caused by the actions your described.

Your transfer switch seperates the AC from the cord and the AC in the generator. There is no way that a normal surge in the cord could go into the generator. A jolt from a lightening strike could possibly arch across the switch, but not a normal surge.

Not going to be much help but how about a clogged fuel filter, Choke problem, blown inline fuse, breaker tripped. I believe that on our PA if you let the rear tank get below 1/4 the gennie will not start to prevent you from running the tank dry. I haven't tested that one out yet

Thanks for the response.

I will try to check the spark, but not sure how to do that. My assumption is to pull the plug and then try to start it and look at the plug for a spark?? I am not even sure I can get to the plug or remove it.

Thanks for the reply. I don't know where the "transfer switch" is located, but in will look for that in the manual.

Thank you for the reply. I have almost a full tank of gas.

Just thinking while reading your response do you have 2 breakers on the gennie by the start button? maybe one of those tripped. My bad, I have never shut the power off before disconnecting from SP didn't know you were suppose to. Good luck will be watching for final outcome. Thanks

Some breakers don't necessarily LOOK like they are tripped. it is best to cycle each one tobe sure. Flip to off, then back on. Especially the genny breakers. And you likely have two spark plugs on the genny, one of which will be nearly impossible to get to unless you have a genny slide out. Be sure and post a fix or progress report when you get it.

There are two breakers on the generator. They have both been reset without result.

Thank you all for replying.

As no one has provided any additional, reasonable things I can look at, beyond my own knowledge, I will try professional help then.

Again, thanks to those that did help.

You said that now that you are plugged in at home all 110 is fine. Is your 12v fine as well while plugged in? When you unplug, do you still have 12v? If all the previous are correct, are you then saying that your remaining problem is that the gen won't start?

Only 3 things will prevent a gas engine from starting. These are spark, compression and fuel. Most of the time you can rule out compression as being the problem, albeit you can check this if you can get a plug out.

You can do a few things to check fuel and spark. For fuel, remove the fuel line or bowl to see if fuel is there when you crank the engine. For spark, remove the wire going to a plug and see if you can see arching when placed about 1/8 in from ground.

The spark may be difficult to see in bright sunlight but there should be a spark as the engine cranks. (There could be a spark from the wire but the plug could be bad so also) No spark = No start.

I do not see any relationship to unplugging your AC power cord or anything on the AC side of the generator for that matter and starting the generator engine.

Good luck. Please let us know how you make out with this.
