Hello Vic,.....

That ONE blink is telling you the machine is shut itself down in HI Engine Temp fault.

We've found that usually leads us to a few things:
1. Broken water pump belt, that will cause hi engine temp for sure.
2. Coolant loss or very low.
3. A build up of scale around the temp sensor, due to old coolant.
4. Bad sensor or control.

The covers need to come off to work on it. You might need to pull it from the coach depending on it's installation arrangement...
