I just posted in this in the National Owners forum, but it fits here too. I recently purchased a National Caribbean. The cruise control is not working. I took it to a Cummins/Spartan service center, assuming they would know how to fix it. They called this morning telling me they have spent the last 3 1/2 hours tracing the wiring trying to find the problem. They also told me they did not have a schematic from Spartan and did not know if they would get it. Now they want to know what I want them to do, keep looking or stop. I just want it fixed!
Look, I'm no expert in wiring an RV chassis. I'm sure it is a very complicated scheme and beyond my limited mechanical expertise. But, if you know where the control unit is, where the power comes from, where the fuse block is, etc., how hard can it be to just re-wire the thing instead of trying to trace down the existing wiring? They want to know what I want them to do? How am I supposed to answer that question? I'm into this deal for $200 and all I have for that is $200 less in my account than I did yesterday. It's pretty frustrating when you take the time to go to an authorized service center and are willing to pay to have something fixed and all they can do is tell you they don't know what to do. Suggestions??
