Getting a code 29 on this unit, it has the micro command system, fwd and reverse contactors were replaced due to being burnt, still code 29, no fwd no reverse, when hitting the accel pedal the line and corresponding directional tips close, code does not appear until pedal gets near full throttle, truck does not travel at all no matter how much accel pedal input, what should i be looking for? Any and all info would be greatly appreciated, and i would be more than happy to share any info needed on any raymond lift truck, thanks.
