Have a code 17 only when accelerator is pressed,Hydraulics work fine. Book says right motor field circuit or faulty logic card. Checked all wiring to right motor all ohms good power and field not shorted to each other or frame. Fault still occurs when field wires disconnected from motor. Replaced h-bridge as i was replacing checked heat sinks replaced with new sheet. They were ohms to plate, good now. Tried logic card still no go. Also tried harness from H-bridge to Logic card. Any ideas where to go from here.
