Hello. My name is Tan.

Locate the switch box on the side of the motor and disconnect the black/yellow wire now check for spark. The switch box is the box that the ignition coil green wires connect to.

Post back with engine serial number and findings please?

Serial number A959118 While tracing the black/yellow wires, I found a 3 wire cluster that was cut. They consisted of 1 green/white 1 blue/white and 1 red wire. They are connected to the 2 solenoids on the front of the motor, where should they go
Expert:  Tan replied 1 year ago.

Those are the trim switch wires. They should connect to the trim switch in the control. You should have those colors coming out of the wiring harness that connects to the engine harness.

# ***** is the switch box.

ok thanks. I disconnected the black/yellow wire and cranked the engine, no spark. I held it against the terminal that I removed it from to check for spark test

Ok we will need to do some further testing. Do you have an ohm meter and a peak reading volt meter or a DVA adapter for your meter?

Ok we need to disconnect the wires coming from the stator to the switch box. Do you have green wires coming from under the flywheel or red and blue?
