I am working on a Crown SP3205-30 serial# 1A266899. Originally the brakes were dragging and upon investigation the outer brake coil was not getting voltage due to a bad brake module. There was also a burnt circuit on the distribution panel to the brake module so I replaced both.
When I power up the truck and step on the brake pedal it works perfect. I can drive in both directions and all functions work. However when I release the brake pedal and then press it again to go, the display says "BRAKES" and the unit won't move.
I checked the brake module test points and found that I lose input voltage to TP5. Does anyone have any suggestions about this? Why would the unit release the brakes work fine until the first time the brakes are applied? Frustrated!
(Sorry to ask this way by bombarding another post but I kept getting an error when I sent this question)
