Tripac APU "Pre Evolution"

[Nilao]

Its not that complicated programming wise. Look closely at the board for any burned components. The fans, solenoid, etc are all run via mosfet. The mosfets are controlled by gate chips, the gate chips are controlled by the processor.

You may be in need of a board like mine was after 35k hrs.

If so and you dont mind used then you can try the thermoking dealer in omaha, nebraska. They sell them from take offs for around 150. I opted for new as they did not have any when i needed one.

The pull wire is on terminal 8SD. It will only be energized for around 2 seconds when the starter kicks on. Then 8D will energize to supply the .5 amp voltage for the hold winding.
