Tom,
From what you are saying, my view would be to try and clean the cable connectors to see if that will help (but doubtful IMHO). Dave Atherton has run into a number of cases where the Aladdin or other data system corrupts the CAT ECU. I suspect you've got a bad Aladdin (and possibly a Siverleaf in your future). But I wouldn't purchase any system until it was demonstrated to work in your coach. Maybe set up an appt. to meet them at an FMCA rally as most are at the International Rallies, e.g Tucson, Syracuse, etc.
Good Luck, Steve
