At the trim pump
1. Three prong connector-wires from trim/handle
2. TWO solenoids. UP - BLUE wires. DOWN - GREEN wires.
3. Motor- 4 wires.
RED Power
Black- Ground
Blue - UP
Green- Down
TWO Solenoids.
4 connections on each
Top posts, both solenoids- Large 10 ga wire, One is RED wire (Power). One is Blue or Red wire which feed Motor
Small posts on solenoids. 16 ga wire
BLACK- Ground
Blue or Green. Up or down from three prong connector and trim button in handle. (low current)
If you press handle button and solenoid clicks do this to test solenoid.
Make a Jumper wire.
Connect one side to Battery +
Now touch other end of wire to either solenoid SMALL post BLUE OR GREEN connection ONLY!!!!
This will act as the trim switch in handle but bypass the wire harness.
If solenoid still clicks and does not make motor run each and every time you touch jumper to small green or blue post, the the solenoid is defective.
If this is the case, REPLACE BOTH as a preventative measure.
If the motor runs each time you jump the small post then the issue is in the wire harness and I would start at the three (3) prong plug.
Of course Follow the connection cleaning first
