Help w/ Blackmax PT&T

[Ulf]

Where are the id #'s located on the powerhead?

I would like to find out what year the motor is.

Problem sounds electrical since you have no sounds. Corrosion on terminals /studs, Possibly bad contact. Solenoid should click. Clean the connections. Brushes are probably tired too. Change, them. Commutator may be bad, and or armature may be bad or need cleaning. I would pull the trim motor, take it down to the auto electric shop and they'll make it right for 60-80 bucks...

Make sure your hydraulic reservoir is full.

So I'm on the boat trying to get to the bottom of this power trim issue.

Jumped the solenoid and motor goes down.

While cleaning the connections I noticed the small wire (green w/ white stripe) pulled out of its connection. Tried to remove connection but the whole post moves.

They make them really easy to get to don't they?

Holding bare wire to this post and hitting down button produces does nothing.

I'm thinking I need to replace solenoid?

Looks like a real PIA to remove solenoid.

Any idea of price & availability ?

If its the smaller wire, that should be the trigger wire to the solenoid. The solenoids are very simple devices and easy to test. You should have 2 large posts (high current in/out) and 2 small posts (ground and trigger input from switch) assuming one of the small posts has a good ground, manually applying 12v to the other small post will trigger the solenoid and make it click. If you have ground on one small post and apply 12 v to the other small post and get nothing, dead solenoid. They don't make them easy to get to. On my motor I have to pull the choke plate off to access the bolts that hold them on.

Your test of holding the wire on the post and hitting button does not rule out the switch or its associated wiring.

Thanks for the reply Basketcase.

Bought new solenoid, put new connection on green/white wire that pulled off the Old solenoid.

Put it all back together and everything functions as normal.

All is right in my world again.

Even did a lil Seacraft/ Jamaica Bar bar crawl some friends to thoroughly test it out.

There should be small freezeplug on the top of the block just behind the flywheel that has the s/n etched in it
