the tach isn't working on the boat I just traded for. I followed Joe Reeves suggestions for the quick diagnostics and learned two things, which I'd like some opinions on please. I'm still awaiting the arrival of my service manual, maybe once I get it I can quit buggin y'all, LOL.
First thing: wiring diagram decal on the breather silencer shows top to bottom for the wires to be connected in this order - yellow, 2nd yellow with gray, 3rd gray, 4th red, 5th purple. The yellow and yellow with gray are reversed. I swapped them but it made no difference for the tach to work. Also doesn't seem to make a difference in the way the motor starts and runs. Should I leave them this way, attached according to the diagram, or just hope that whatever mechanic that worked on it last had a good reason to reverse them?
2nd thing: I left the yellow and yellow with gray wires attached according to the decal above. I took the gray wire loose, attached it to the yellow with gray (which I thought was the right one according to Joes post) and it did nothing. I then attached it to the yellow and the tach started working. Is it ok to leave this wired this way until I can get a new rectifier? I won't be long to get it, I just have to decide if I'm going to make 40 mile trip to the nearest marine parts dealer, or order them from here. I do need a few other things, so I might just make the trip over there and maybe get to pick the brain of one of the service techs a little. They don't seem to mind answering a FEW questions from time to time.
I've managed to get the motor to start and stay running, and now that the tach is working, I have it idling about 1200 on the muffs. Was going to take it to the lake and put it in the water for some adjustments, but it's supposed to storm this afternoon, and as impatient as I can be sometimes, I know I'll be better off to wait for the manual to arrive.
