Hi Gang! Been too busy of late to do much more than lurk and like a few posts...
Needless to say, but haven't had much time to work on Raylan the truck. That's changing now that we're getting caught up and there's not much work in sight for the foreseeable future...
Anyway, some of you might recall that I've been having trouble with the cruise control in that it failed on me awhile back before we left upstate New York. Behind the curve, we had to head south with our fulltime RV before the freezing weather caught us. A month or so before leaving, Chris @chillman88 and I put a reasonably recently rebuilt and upgraded e4od in. Upon leaving NY for Florida, pulling our 10k+ RV the OD light started tossing codes! I was pretty freaked out, we were hauling about 96% of our worldly possessions behind us in addition to a work deadline to meet... Code reader was telling me that the converter was bad. I didn't want to believe this because I'd just had it rebuilt with triple disc and billet by the shop that did the original tranny build for the OB member that I bought it from... After a lot of fretting and head scratching, I figured it was at worst, an electrical problem of some sort and out of an over abundance of caution, completed the trip with the OD locked out. Other than being slower than I'd have liked, the trip went without event. After getting settled in Florida, when I had time I attempted to track down the problems with the transmission and the cruise control. Since they're both electrical, I'd thought they could be related. Doing the cruise control trouble shooting with a multimeter, I discovered that the cab mounted third brake light was out. This was not obvious since the cap is tight against it - out of sight, out of mind! Because of the necessity of removing the cap to change the bulb, I elected to install a resistor on the brake switch. The resistor had no effect on the cruise control - still non functional. No idea if it affected the transmission, as it only kicked the trouble light when towing heavy. This led me to believe that in addition to the faulty brake light, perhaps the VSS sh*t the bed... which leads me to today. I replaced the VSS and went to run some errands. Once up to speed, I engaged the cruise control, it worked!! I tested all functions and everything seemed fine. After a short while, I noticed that it seemed to be having difficulty modulating the throttle, pretty subtle, but I could feel it was surging... 4-5 miles down the road and the throttle released and once again, the cruise control quit working. The speedometer is fluctuating, maybe 2-4 mph at 60 RPM's are solid and GPS speed is steady. What could it be??
As always, many thanks for your help!
