Hi all i'm new to this forum which I just found through google!
We have a facelift header on a year 2000 NH TX64+ that has a problem with the reel speed motor voltage supply, the motor has bench tested with a 12volt battery perfectly well.
However when the reel speed buttons are depressed on the combine control stick, the supply wires are only outputting 2.5volt jumping to 3.5volt and back down again if continually held.
I have checked the 3 fuses in the processor box that relate to the reel speed and it's motor. I have undone the main harness plug from the motor into the processor box and all is good there, I have tested the voltage at the connector plug where it connects to the header at the end of the harness, and it's still the same.
Now I assume there is a some relays somewhere that control the motor running backwards when the switched is pressed one way and forwards when the switch is pressed the other way, but I cannot find these relays and the manual does not mention them (the combine is fitted with reel synchronisation, could it be because of this the reel syncho kit was fitted by the dealer at pdi and the relays are located elsewhere and not mentioned in the operators book?)
I've run out of ideas and I don't have a wiring diagram for this machine (does anyone out there have one they could post on here or send a pdf to dancoates(at)hotmail.co.uk)
