I am having some issues similar to this the truck I am working on is a SP3000 it was having intermittent issues changed out distribution board was running good for 3 months now when asking for travel Gate shows on display but when ever you depress the dead man pedal the K3 relay starts to engage but goes crazy due to getting only 9voolts to the coil I have tracked the wiring on it and the power is coming from the thermistor in the brake module changed it out and I am still having the same issues I am wondering if any one has any ideas. also the brake coil has been swapped out all connections to the control card as well as the distribution board have been checked I checked for any shorts in the over mast cables all check out ok. no codes are being thrown at all on this unit.

thank you fort any help

Fact of the week
Brothers Adolf ("Adi") and Rudolf ("Rudi") Dassler split their shoe company after WWII due to a bitter feud, and established the rival companies of Adidas and Puma. Their personal animosity and business rivalry divided their German hometown Herzogenaurach. The town became known as "the town of bent necks" due to the intense loyalty to each brand.
