Has anyone had this happen to them: Before my last trip I started the GenSet to cool off the coach before we got underway. Started the Generator and it ran for 2 seconds and cut off. I tried to restart several times but in all cases it cut off. Called Tiffin and the tech walked me through a reset sequence. It started and I ran it for minute and cut it off thinking I was good. When I got home I went to vacuum the floor and guess what. It ran for 2 seconds and quit. Called Tiffin again and this time we narrowed the trouble code on the start button to a High voltage overload. To make this long story short, the block heater was plugged in and the breaker was on. This load caused it not to start. Unplugged it and the Generator has worked flawlessly. In the past this thing was active and it has just decided to tank now. I am thinking there is a relay that has gone out on the heater circuit.. Any ideas. Thanks.

I pretty sure you have an automated transfer switch that has a built-in delay so if the generator only runs 2 seconds before it dies, it hasn't even transferred load yet. Hopefully it never happens again, but if it does you might want to shutoff the circuit breaker on your generator and see if the generator will stay running. If not, you likely have a generator issue. The fault code (blinking light on the switch) should give you an indication of what is wrong.

Should start the gen set with a load on it.

Why do you have your heater block on in the summer

Lots of people have found their block heaters plugged in when they had no clue they were. Came from the factory that way. First thing I did was unplug that thing since I had read of issues with it.

I also never start the genset with a heavy draw on it. Give it a couple of minutes to get up to speed and then turn on the ac's or whatever. Never good to run the genset when shore power is present either.

Ok. Stupid question. How do you unplug the block heater?

Thanks for all the info. Yes it does have an automatic transfer switch. When the generator is started until the transfer switch kicks in, you can tell this has taken place by the change in pitch of the generator and the microwave comes on, a tell tale sign. The question is why with the heater plugged in why is the outside the makeup of the transfer switch. Several months ago you could start with everything including the heater plugged in and now it won't run with it energized. Still can't figure that on out. However now the breaker is off so it should not make a difference. By the way the block heater on mine is in the back compartment on the passenger side of the coach. Thanks again.
