so i went to go start up the boat the other day and i wasnt even able to trim the motor up off of the "kickstands". it made a light clicking sound that came from the trim (up and down) relays. sounds like the motor isnt getting the correct voltage to fully power the relay, so the relays just click and never turn all the way over.

so then i decide to just try to see if i can crank it over, nothing. i checked the voltage at the hot end of the starter solenoid and the "cold" end while i cranked it over and there was no voltage on the cold side. on the hot side, the voltage was equal to my battery. i used a jumper wire and hit the starter and there is plenty of power to crank the motor over.

so my question is, is the solenoid bad? i think its something else because i dont have use of my trim motors either. i used the motor block as my ground during my voltage testing and it was the same voltage as hitting the battery directly.

1996 88spl with electric trim, been sitting for ~2 months. not too long, as i take it out pretty often.

1. Disconnect the battery-BOTH terminals.

2. Remove the negative terminal from the engine block and clean the bolt, ring terminal and the bolt hole.

Reassemble in reverse order.

classic signs of a corroded ground?

my battery terminals have absolutely no signs of corrosion, and i didnt think my block ground had too much corrosion either, but i didnt take it off and clean it.

Yup.

Classic issue with any outboard with a non regulated charging system. That is what you have.

Nobody looks at grounds.

yeah, i was going to get a starter solenoid but then i stopped after i thought about it becuase the trim and the starter dont work.

the thing that trips me out is when i clip a jumper wire to the positive on the battery and hit the starter with it, the starter pops out and definitely turns the motor over. no problems with a ground there. only to the solenoid and trim system i guess. it seems like a ground issue, but thats what threw me off.

A lot of good parts, regardless of what it is, have been replaced due to faulty grounds.:(

Let us know.
