Re: Anyone help decipher powerscreen wiring 1995 RT?
Sounds like the relays are good, as is the handlebar switch and the motor, and if there are no obvious wiring faults I would be looking at the up and down position limit switches.
I'm guessing the relays don't operate (click) when you press the handlebar switch - and the power to those relay coils goes through the position limit switches,
You could disconnect the wires from the limit switches and check between pins 5 & 6 on the down switch, also pins 1 & 2 on the up switch with a multimeter.
I would expect the limit switchs to go open circuit when the screen is either fully up or fully down (one switch controlling up, the other down) this is what stops the motor when the screen gets to the end of it's travel. When the screen is somewhere in between fully up and fully down, both switches should be short circuit across pins 5 & 6 and 1 & 2 respectively.
So many places, so many roads, so few days off work.
