Tach for Mercury 135hp on not working except when tilting motor

I recently had much of my ignition system and stator replaced and when I took it out for a test drive.-- the tach would not work. Everything else seem to be ok. I then notice that when I operated the trim on the shift-- the tach worked as long as I was holding the trim switch on. This is wierd to me and I plan to try and fix it Memorial Day weekend. If anyone can give me a hint I would appreciate it very. Much. The alternative is to take my boat out of the water and trailer it to the repair where it will sit for a week or so. The mother is a 135 ho Mercury on. 1990.
