Hi guys,
I'm new to this forum after I found it while searching for answers for some issues I'm having with my '90 yamaha 40hp 3 cylinder autolube (40HEPO). I hope some experts van help me with these.
I recently bought this engine after it had been in storage for well over a decade. I changed the plugs, impellor, gear oil and cleaned out the carbs. It runs really well.
I aquired a yamaha analog tach (6Y5835400500 w/oil lights) which I want to hook up to this engine. When I tried to hook it up I couldn't get a tach pulse coming from neither of the two green leads coming from lighting coil. Also I noticed not any increase in voltage (on my dash mounted volt meter) when the engine is running. I know the tach is good but after having a search around the internet I found clues that possibly my rectifier is toast and this in turn could cause the problem with the tach signal. I hope any of the experts here can shed some light on this. I'm just getting started into doing repairs on my outboard but I have pretty good mechanical skills. Any help is therefore very much appreciated.
