I tested the aux solenoids' and am getting 4 ohms (3.89) on both. I see that on the aux power (Green/red) wire on the rear solenoid when I trigger the switch I get 7.89-8.1 and it goes back to almost 0 volts when I push the trigger again. But on the front aux solenoid power (Green) wire when I trigger the switch it goes from almost 0 to .38 volts. So I'm thinking this is where the problem lies.

When I press the aux button on the right side control panel both lights stay solid green. I do see the BICS panel lights. The connector under the seat is disconnected but the seat light come on. I do have a single flash on the traction light which says the traction lock hold coil circuit is open.. I'll look at that next.

But my biggest concern is whether I can open the aux solenoids with the arms raise(back pressure?) or is there just high pressure behind the solenoid.

I have read where there is a spring that gets stuck when not used for a long time. Can I open the port to check the aux spool? or do I need to relieve pressure somehow before removing the plug or aux solenoids?
