I think it’s a bad connection somewhere. The trailer up button will click but the outdrive down button won’t go down or click. The outdrive up button doesn’t do anything or click but it’s already all the way up. I checked the connections but I’m not really familiar with what I’m looking at. All the connections are good, except this one bolt, I’m not sure if it’s positive or negative but I’m getting nothing with my tester.

The Red wire with the nut on it connects to a fuse. The fuse is the square thing under it

The black tube is another fuse which is inside it

Take a voltmeter and see if there is voltage on each side of them

It looks a little burnt.

the power cord is fine, it’s always looked like that. I checked the fuse and it’s fine as well. It’s just that one terminal that has no conductivity. Is that solenoid bad? Is that what that means? It had no power, no ground and read 0 ohms.

No
Need more testing
Power comes from the red wire thru the connector in your pic. Then goes up to the throttle handle to the trim switches. Then comes back thru the same connector to the relays

Take a jumper and go from the terminal with the nut on it to the small terminal your arrow is pointing to. The pump should run and the drive will go down

If this works, then need to figure out if the problem is a bad switch, wire, connection or that connector

Thanks for the diagram, I’ll try the suggestions hopefully Wednesday! I was sure it was a bad connection, it’s been like that twice in the past year. Somehow the bolts get oily and don’t have a good connection, I was hoping it was the same issue again because obviously that’s a quick fix but then again.... it’s 30 years old.

The inline fuse had power and the red block had power. Didn’t have the time to bypass the switch, I’ll use a small thing of wire to test that tomorrow hopefully.

I bypassed the switch and nothing....

Did you jump from the red wire to the small post your pic is pointing to?

Which switch did you bypass?

yes, I jumped from the red power wire to the post that has my arrow pointed at it.
