GA_Boater Okay, let me get some answers for ya!
The engine performed normally (electrically) on 13 Jul 20 which was the last time we were on the water. It cranked fine when started EXCEPT ONCE when I was ready to move to another spot. At that time, I thought that I'd not properly recentered the shifter. So I moved the shifter forward, then into reverse and back to center. Then the engine fired right up.
Since that time, the engine has been in the garage at home. We replaced the carb coupler assembly a few weeks ago and may have bumped something loose with the wiring during the process. Maybe. :noidea:
We've been working on the starter/ignition issue for a couple weeks. Mostly due to waiting for parts and other non-boat related stuff. But the engine HAD been cranking/running normally the last time it was used. Then suddenly didn't do anything at all when the key was turned recently. That's what started (nyuk, nyuk
) this round of troubleshooting.
As part of our testing, we discovered the ugly Y splice. We cleaned that up and I ran a ground wire from the starter mounting bolt to the negative solenoid terminal and the upper mounting bolt for the solenoid. That's the upper part of the Y. But I left the single lead open, which is the lower leg of the Y.
Once that was done, the motor cranked normally. So we prepped it to start and it fired right up. But it wouldn't shut off. That's when I got zapped.
Over the last few days, we reconfigured the Y splice back to the way it had been before I ran the lead to the starter mounting bolt. After we reconfigured, we get nothing when the key is turned.
We continuity tested and the Y splice assembly single lead goes through the harness connector Pin 4 and all the way to the key switch, Pin M.
Thanks for telling me that the Y splice was put there by some Previous Owner. That was a real aha! moment! :encouragement:
And thanks for the reference to the mercury switch and path. I understand the circuit better now. I'll be looking closely into that area. :joyous:
We weren't able to work on the boat this morning and likely won't this evening. Maybe tomorrow I'll be able to get out there and untangle that harness to get it cleaned up and organized. Then I can trace the wire from the mercury switch to its source.
This is the way the Y splice is now. Although I don't know if it includes the mercury switch or not. I'm thinking that it's passing through the kill switch as well, since it tested continuity normally.
