You might try W.W. Williams in Las Vegas. I use them in Tucson for all my service here and they provide excellent service on for just about any chassis work.
I agree with everyone else. Had the same problems several years ago. Bad ground too instruments. Find that ground wire that comes off the instrument panel and run a separate wire to a good chassis ground. Good luck.Jack

Cummins told me that number 1 and number 6 cylinders were leaking. They explained it as shrinking. On my engine the two part manifold is not available. I have 125,000 miles on the coach and she is 16 years old.I know about CAC's replaced that two yea...
