Is there a circuit breaker on this Transom/Gimbel housing mounted trim unit? Relay's click, trim motor not running. No up, nor down movement. I have the normal rocker switch on throttle lever, and dealer-added transom switch. Both initiate relay clicks. I see two heavy gauge Green and blue wires that I believe to be the main current to motor that have one each major splices, but also have a plastic male connector (GreenWhite/BlueWhite) that looks abandoned (smaller gauged). (Looks like maybe some non-standard wiring, possibly when the dealer wired in what looks to be a Mercury transom switch). All seem to go into harnesses so a little lost at the moment in troubleshooting other than completely pulling tilt/trim unit to test motor. It is the redesigned unit (reason for splices?). Should I hot-wire into the heavy gauge wires to see if motor reacts? If that is the power source and the motor fires, then an electrical issue must be is upstream. Hoping for a breaker somewhere as it's often referenced, but I don't see any anywhere. Fuses and relays on engine box look good to eye.

With relay clicking then they are working, might not be passing current to the motor. This is the wiring from the handle to the relays. Need a voltmeter and follow the voltages

Here is a couple pics showing wiring and connections
