Hey! I can see what you mean now! lol
Looks like a disconnect so you could replace power pack if needed and not have to cut the wire to the red plug.
Is that the wire you replaced? it's now red on the pinky side?
Anyway, you could disconnect there as you've done before.
Then put red meter lead into that boot (pinky side) and then black on engine block.
That'll tell you if it's grounding in the engine side at all.
Guessing not since you just replaced the wire it seems. haha!
But, that won't tell you if it's shorting on the boat side. Reason for that is, the battery isn't connected. The ground in the remote and the ground on the engine aren't connected...
I guess you could take all the wires that would normally go on the negative post of your battery, and keep them connected together somehow... Then you should be able to use just about any ground.
Otherwise, do you have a length of wire that might reach from the engine to the remote so you can connect to the same ground that the "M" terminal on the ignition switch grounds to?
Then you can put red lead into the boot at the pinky, then the black lead on the wire going to the ground in the remote.
If it beeps or shows other than 0.L (with key in RUN or START) you work your way towards the remote.
Next spot would be to unplug the big red plug and put red lead into the terminal for the black/yellow on the boat side of big red plug. Does it beep there?
So on and so on towards the remote till it doesn't beep anymore..
Once it stops beeping, your issue is between where it stopped beeping and the LAST place tested that DID beep...
I hope that made some sense and didn't confuse you...
I'm not convinced I explained that very well at all, but I hope you get what I mean... LOL
