I though about that after I sent the post - I was concerned that the TRAILER
switch ran a different circuit in the pump which allows the drive to extend
past the limit switch. I am trying to eliminate the pump as the problem and
possibly focus on a simple failed switch in the controller.

I have a 1999 Mercruiser Alpha ! Gen II sterndrive. The power trim does
not go up with the shift mounted control, but does activate with the
TRAILER button.

The service manual suggests that the switch may be faulty. I also have
some trouble shooting info in the manual to try. The trim pump is located
in a hard to get at location. before I try to get at the pump, I though I
would ask the group for suggestions.

Thanks in advance....

Dave, if it works from the trailer button, doesn't that eliminate the pump
as a potential culprit?

Check the switch, the connectors to it (corrosion), look for a pinched
lead between it and the stern.
