Onan RS12000 Fault Code "32" Issue

My unit is 7 years old, has 2700 hrs of operation, sports the Honda 670 motor, uses LP, operates at 8600' elevation, backs up a 2200-watt off-the-grid solar panel, 24-volt battery system. I have experienced various problems over the years and unfortunately, my dealer has refused to service my unit since 2006.

My current issue is a "Service Fault", fault code 32 - "Low Cranking Speed Sense". All fixes suggested by the manual (i.e., clean and check battery connections, recharge or replace battery and/or change oil to recommended viscocity) have not corrected the fault indicator. The generator fires up within 2 seconds and shuts down after 2 more seconds followed by the service fault indicator (3 flashes).

Does anyone have any other suggested fixes? Is there a way to dissable or bypass the sensor? I'm sure the Controller Board is malfunctioning in some way or sensing an incorrect fault which results in shutting down my unit.

Thank you in advance,

DS
