This was the third year in a row that the GMC -Saguaro Jetset Christmas rally has been held in Ajo, AZ and hosted by Jim and Adelle Decheine and Bob and Anna Frazier. It is a pretty short trip – around 150 miles – and there are two choices for routes. The quickest one is interstate highway for about 60 percent of the way there and the other is two lane highway through the desert (and the indian reservation) all the way.

The coach ran great as usual but we noticed that we touched ground in the rear pulling into a driveway part way there but thought nothing of it at the time. Once we got to the camp ground though I did notice that the air suspension system in the back would not turn on. I diagnosed the problem as the power relay that supplies power to the air compressor. I happened to have a spare one so I wired it in in place of the old one and it fixed the problem.

I also learned some things about Onan generators. One of the other GMCers there had a problem with his Onan not starting. It did have a Pertronix solid-state points replacement unit installed but, unlike the current way of installing them on the flywheel, this one was installed in place of the original points. It still utilized the push-rod mechanism and it had work the back of the unit out a little and that resulted in the magnet not passing in front the the pickup as it had done before. We readjusted the unit and the Onan fired right up.

We had a good time and no trouble.
