Install the starter solenoid surge suppressor diode. This would have been a lot easier at an earlier stage. It was very difficult to take out the mounting bolt of the solenoid and then reinstall it with one of the leads of the surge suppressor connected to ground with this bolt.This was service buletin SB92-01 which requires that a surge suppressor diode be connected across the solenoid coil of a starter relay when an A-510-2 ignition switch is installed.
