I'll do my best to describe what has happened and the troubleshooting I've completed.
What happened:
Engine is regularly maintained and used weekly. Ran a couple of hours on Wednesday, no problems. Flushed after use, stored on lift. Saturday morning, I tilt the engine down and attempt to crank. Just after turning the key, I heard an audible pop-- I thought I'd blown a fuse.
Symptoms:
1. Power tilt/trim does not operate. When activating up or down from both the remote or switch on the engine, the PTT motor does not activate. However, the PTT relay does click
2. Starter motor does not operate. When trying to crank the starter does not engage, but starter motor relay does click.
3. When ignition switch is turned to ON (not START), the self diagnostic system does not complete-- the lamps on the gauge flicker and the buzzer flutters. Not the usual 2 second beep with all 4 lights on. When the ECM main relay is removed, the full beep returns and the lights illuminate as normal.
Troubleshooting so far:
-Confirmed full charge on battery.
-Inspected all connections from battery through to engine and to electric parts box in engine. All are clean and tight.
-Removed and inspected all fuses: 60A main and 30A sub in engine and 15A in line between ignition and engine. All fuses are good and show continuity.
-Removed and inspected PTT relay, starter motor relay and ECM main relay. All test OK and are within specified resistance ranges.
-Confirmed full voltage to engine and through to downstream of fuses.
I'm hoping someone with more experience can point me in the right direction here. Basically, I'm getting power to the engine and through the relays, but neither PTT or starter are operating. The onset was very sudden with no obvious cause.
Looking forward to hearing your thoughts on next steps to track this down.
