I returned from a day on the river Sunday, during which my boat performed without any problem. When we were putting away the boat into the garage the next night, I was having my son lower the outdrive to relieve pressure on the bellows. In order to raise the trailer tongue to get the bow higher in the air, I asked him to raise the drive a bit. It did not respond to the Up trim switch (we have a rocker switch on the throttle handle). The down trim switch continued to work to lower the drive, and the trailer switch also continue to work to raise the drive. When the up trim switch is pressed, there is no noise, no click, no pump hum, etc. It just doesn't work.
I consulted my Mercruiser manual (I have a '97 Mag 350 with Alpha One Gen II drive in a Larson 186 bowrider) and it suggests I test and clean the connectors between the trim limit switch and the trim up/down switch. From the diagram, it looks like the connectors should be somewhere closer to the drive unit than the throttle unit, but unfortunately, I can't seem to find anything that looks like connectors. There is a large bundle of wires entering the engine compartment from the front of the boat, and I cannot see where the connectors might be.
Before I clip the zip ties holding this big bundle of wires together so I can trace back the individual wires to see if I can find the connectors, or try to trace back from the trim control wiring harness connector, I thought I'd see if anyone had any thoughts on where I might look. (Also, if you have thoughts on whether my diagnosis is on track, those would be welcome, too.)
Thanks!
Jim
