Ok, time for me to play "stump the stars"--Is it possible to re-wire a 2003, 90-HP Mercury two-stroke, when re-installing the power head, such that it affects the operation of the trim switch at the throttle?

Indications: The trim switch on the motor works fine in both directions. The throttle switch works ONLY in the down position. I've taken the throttle switch out, cleaned up some minor corrosion and reinstalled, but it still did not work in the up position. I then took the switch to a local Mercury shop, and they were kind enough to test the switch with an ohmmeter, it tested good in each direction, several times.

History: I recently had the steering tube replaced, which required the removal and re-installation of the power head. Before I go back to the out-of-town shop (nice guys) it would be great if I had some additional info which might help us troubleshoot/correct it. If someone knows of a 'gotcha' that my mechanic may have overlooked, I'd be grateful to know about it.

Anything is possible. I'd be taking my factory service manual
and trace the wiring for the Trim/Tilt under the cowling. My
guesses:

1. There's a connection that's not quite seated.
2. They managed to pull back one of the pins in the connection.
2. They pinched a wire.
