Simple engine fuse question (hopefully)

I was messing about with my outboard engine trying to get a non Yamaha tacho working with it and I think I've fried a fuse somewhere, as since then it is completely dead, electrically speaking. There was a brief flash on the wires I was working with and the engine carried on running which is a good sign it's nothing serious, but when I switched it off it was then dead when I tried to start it again. Do motors like this have a main fuse box somewhere? It is a 1989 Yamaha 60 AUTOLUBE 2 stroke. Though there is over 12 volts at the battery, and the same on the engine ends of the fat leads from the battery nothing works on the engine incl, trim/ tilt and starter, which is making a mess of my boating plans. I've checked the killcord is correctly in place and waggled it etc. and all seems as it was. As it was running fine, I'm sure it will be something silly, but can't for my life work it out. Any ideas? Should i be looking in the engine itself or the control box.
Many thanks

I can only go off my Yam 115 which is a bit older than yours. There's a inline fuse ontop of the rectifier on mine.

Yeah, there will be a fuse lurking in there somewhere. The remotes are fed from the engine.

If you have problems finding it, remmeber you can turn the screw hidden (o nthe (I think) Starboard side of the PT unit to release it & can then use as a manual tilt, then pop the lid & use the emergency pull start. (you will need the key in and at the "run" position, as the "off" position does the same as pulling the deadman)

If you find the fuse you won't need to do that tho'.

On my 20HP 2005 Yam there is an inline fuse on the port side of the engine near the front - there is a spare fuse clipped to the holder (or very close). IIRC it is just in front of where the two large battery leads are connected to the engine.

To me it sounds like you may have fried your solenoid which takes the + direct power feed from the batt.

You should test the solenoid.
