yamaha 40hp electicity problem

Hi guys,was wondering if anyone has a wiring diagram for approx 1980 2 cyl 2t yam? i think i may be coming to the steep part of this particular learning curve.bought un-tested motor,spark appears utterly absent.have studied all relevant threads,cannot find any elecricity coming from magneto.think the motor has been converted from electric to manual start,so there are more wires than strictly necessary,but i think im testing the right ones, ie the only ones that seem to go anywhere.(one to ground,and one brown) should my next move be to remove and inspect magneto?
I saw some guy saying "a boat is a hole in the water,surrounded by fibreglass,into which you throw money",i'm worried now. Help!

Just before you start ripping the engine to bits, your deadman is in, isn't it.....?

If it is, have a look at

Scroll down to almost the bottom, that might give you a lead......

forgive my ignorance,but is a deadman the lanyard thingy that cuts the motor if you fall out of the boat? if so,it doesnt have one,it just has a kill button. thanks for the link,that is very useful.am now looking for a local black box dealer....

Yes.

Does your stop button have a groove behind the red bit? if so, put your fingers behind it & pull. If it moves out, your lanyard is missing, so it thinks you've gone for a swim........

Needless to say a new lanyard is going to be a lot cheaper than a new black box of any description........

How old is it?

My old Yam had a thermal cut - out switch bolted to the top of the head that shared itl;s circutry with the deadman, theory being an overheat just killed the engine. (Donlt you just love old technology!) Doyou have something similar? If so, just disconnect it & see if things improve (it's normally open, closes on too much heat)

On a similar theme, unplug your stop switch & see what happens.

How old is the engine? I guess quite if you have a rubber covered stop button.

Before you go spending 50 quid on it, do a compression check with a tester and post the results. They should be within 10% of each other at worst or there's no point in fixing the ignition.
