Worked on coach some yesterday, my reservoir doesn't have any electrical going to it or any threaded bosses for a sensor. Could not find any electrical hookups at pump, motor or control valve other than 2 wires for solenoid on Vickers control valve. After finishing oil change today I will run coach long enough to get radiator fan to cycle on. Then see if 12v heat exchanger fans come on. If not I'll start ringing out wires and see why fans don't come on. Appears Newell changed how the cooling for the hydraulic fluid operates close to the time between David's and I's serial numbers. There is an unmarked relay and a auto reset can type circuit breaker that is in rear engine bay panel. It gets it's power from a short wire to dash power contactor. If this turns out to be the relay for exchanger fans, I'll take a picture and post. Thanks for everyone's help so far. This is actually a good topic for everyone to know how their system operates.
