No the winter lever switch is all intact with the hose and all. Interesting you mention this. I am a big fan of the winter lever on these gensets. I have noticed a big difference when using it too.

I needed to take my coach down to the tire place yesterday to get a spare mounted. It's been cold here (30s) the past week and it was cold in the coach when I got in. I started the coach and then pushed the genny start - nothing, not a click or anything. I remember reading in one of the topics here that you need to prime it by pushing the stop button for a while so I did that, not sure if it did anything (I'll have to read the manual on this 7.5k) because I pressed the start and still nothing. Then I remember reading that I should just press and hold the start button for a while (like 10 secs), which I did, and then the genny started up.
A side comment was I then turned the AC control for the rooftop AC to furnace for the first time since I bought it and heard the furnace fire up and after a while it was warming up in the coach At least I know that works now.

Just about any solenoid can be taken apart. Of course they are destroyed in the process in some cases but to demonstrate they are defective it is fun to get to the contacts to show peopleT.

Could you post a picture of the solenoid please. The conventional silver devices with the roundish top that has been pressed on and then rolled over a lip can be taken apart by either cutting straight through just below the cap or prying the edges off slowly.

Here are some examples of an ordinary solenoid used in many applications.

You can see it is a very simple device.

Actually thank you YC 1. The one you have pictured is exactly the switch my generator uses. But they used more plastic when manufacturing mine. Don't have the time to takes pics right now. It would mean pulling the circuit board back off. Life is busy, busy, However As soon as I have a minute, I'll post a pic of my solenoid switch as it is installed in the control box before I remove and discard it. I don't know if I'd actually go through all the work to tear the old switch apart when I can install a new on 5 minutes. In my life it gets busy enough it's crazy so I barely have enough time to put the new switch in, start up the genny and run off to another side job or another meeting. However thanks for the pics. I'll be putting the new switch in a few days here. I'll let you all know if this solves my starting issue.

The extra ten minutes to take the old one apart and snap a picture would help to convince others having similiar issues that it might resolve theirs.

Just saying, paying it forward is appreciated and I sure would appreciate it because I will use it as a reference in the future.

You can sleep when you are dead. I used to work half days, sometimes a bit more but that left 12 hours for fun and games.

That's just your basic "ford" fender mount starter solenoid. $12 at any auto parts store.

I may have missed it but no one spoke of what Oil you are using. If straight 30 weight on a cold morning thick oil can contribute. However I would think 40 degrees would not make much difference.
