Here I go again! Regarding our transmission issue (erratic shifting) in South Dakota, it seemed to have repaired itself (remember, I changed chassis batteries in Rapid City and was told that the transmission must re-learn its sequencing) about half way home to Texas. That was in early October. Then we departed for the Kerrville rally, it began again but seemed to fix itself again. I did the fault search, and it reports that I need to check the "speed connections". I presume that is engine speed. The transmission then continued to mis-behave on the way home. It seemed to be searching for where to go, as sort of a "double clutch". It would begin to shift, hesitate, engine speed goes to maybe 2200, then the shift would complete, back to 1500 RPM. Did this the 5 hour trip home. I have no idea where to look for the speed connections.
On arriving home, I found that the engine fan (the fan that discharges air from the engine compartment) failed to come on. Trouble shooting found that there was 12 volts at the terminal in the terminal bay and at the fan connector in the engine compartment, but as soon as the fan was to start, that voltage would drop to zero. The fan operates properly when 12 volts is applied externally, so the fan is not the problem. I also tried another fan at the connection in the engine compartment, same result. 12 volts is applied to the relay by the circuit breaker, but once the timer tells the fan to start, the 12 volts drops at the terminal to the fan, the circuit breaker is OK. Could the relay have become a resistor and drops all the voltage? Are these two issues, or related?
