Additional Info: OK, my question on battery / system voltage was an inquiry after reading the following comment from ruko_ruko: "...I became aware of a probable low voltage situation when I switched to "service mode" on the module and turned the key to start, the start relay would just click and stutter. Also noticed the running lights, which have nothing to do with the module, were not functioning with the key in the on position. Really cleaned the battery cable connections, put a 10 amp charger on the battery, got the volts up to 13.6 steady and now the unit runs just fine,..." My battery voltage, not running, is ~12.8, running it's ~13.5. Additionally, after swapping the new seat safety harness and resistor-diode link, I have found that the when the SOL LED light goes out on the control module, (with no other warning lights), if I reduce the throttle for a moment and then rev it back up, the SOL LED will reset and function normally again,... at least for a limited time. Are there any other issues that could cause this SOL LED issue? Fluid? Pressure? Flow? Filter? Electrical problems are frustrating!If you shut down then restart, i can't see it being a bad battery. A bad battery, i'd think would be hard starting, if at all.
