I recently bought a second hand classic 50 , I think its mid to late 80s. The block has serial numbers 1017-8359 and the outside bracket has 1449 7373 stamped on it and it's an Australian motor , I think the motor is an 83 mod?? It has coil packs for each cylinder.<br />When I removed the cover I see that a few wires are cut. There is a grey coloured wire that ( Tacho)??<br />2 light brown wires and a black and yellow wire that is cut.<br />I did a google search for a manual ,but manuals seem to go till the year 70s, then 90s onwards.<br />The controller is from another merc and it to has brown wires cut and a black and red wires cut.<br />Has anyone got a wiring diagram please?
