Hi all, This problem is intermittent on my 1990 1500. Sometimes the cruise will not set and this coincides with 3 of the 4 rear lights not working either. Any ideas

Most likely a bad ground. Under the seat on the left side there is a 22 pin connector. It is inside a black plastic housing. If the bad ground is there one of the pins will be burned. I don't remember the wire color code.

Just went through this myself.
Under the left side of the passenger seat is a 22 pin connector housed in a plastic case.
The green wire is the ground to everything on the rear of the bike.
You'll find that the green wire is burned and has melted the plastic connector.
When that ground goes bad, all sorts of weird things happen.

Put your fix here moggie1300 instead of starting a new topic, so this gets the fix you did for those that read this later using the search tool.
