New holland TM125 emu pto fault

[smokinjoe]

I have an emu control unit from a TM125 for repair with the problem of pto shaft not operating, the fault is definitely within this unit as a temporary replacement has been sourced and I'd like to identify the fault with the original if any members could help me out with pinout of the control unit or any general information that may help,part number is 82021839 and the plug is 36 pin
Thanks.

Whats it not doing ?
If just pto
Probably start with replacing the transistors with the large heatsinks to your right of the relay.
Also check the diodes as Ive had to replace these in the past too.
If its the processor ..BIN !

If you do not have the correct desolder ( and I dont mean a solder pump or brade) equipment leave it alone as the board dont like being reworked too much.
