1997 40hp 2cyl mariner how to test trigger
Hi, i suspect my trigger is faulty! and i dont know how to test it. i think one or more of the three wires (black=earth, purple=CDM 1, white CDM 2) may have a intermitant break in it. i noticed the outer Braided sleeve is badly frayed just where it go into the trigger unit! i have been trying to get the link and sync set up as per the manual but the engine seems to cut out when the timing is advanced anywhere near the 6° mark at tick over!
it will start at a highish tickover and the timing is at approx -10° but when i advance it slowly by hand it will suddenly cut out anywhere between -4° to 6°.
last week after trying for hours it just seemed to work and i was able to advance the timing mark thro 0° and on to the spec 6° mark and it was ticking over at 800 revs in forward gear at 6°. it ticked over fine for 30 minutes and i turned it off thinking the link and sync was finally done. thinking about it, i didnt rev it up at any point then and so the trigger wires were not disturbed) but when i tried to restart the engine it would not tick over! ive been trying to redo the link and sync but it just cuts out when i advance the timing. can anybody help? the manual dosnt tell me how to test the trigger unit.
