1971 mercury 9.8 no spark...help the omc guy out

[altrocker1]

so, im getting more and more used to working on johnsonrude ignition systems so this one is a bit of a mystery to me. i got this motor this weekend for cheap so im trying to get it going quick to see if i want to keep it. i've always been a fan of the 70's mercs so i would love to have one of my own.

at any rate, i pulled the flywheel and it all looks pretty good under there. the "insulator blocks" that are the usual problem seem to be in one piece, however the wires that run from the point screws to the coils were frayed so i pulled the little screw terminals from the back of the insulator blocks and i soldered some new wires to them. now i need a way to insulate the new wires on the back of the blocks since they are completely exposed. any thoughts. i put it all back together after i "fixed" the wires and there is continuity from the point to the coil, but im assuming that the high voltage can still arc from the open back of the insulator blocks to somewhere on the assembly...so im hoping some sort of silicone will fix that.

as far as the stator goes, its really clean and it doesn't have any cracks the wiring or the green insulation on it. it looks really great. however, i still want to know how to test it. i've found a bunch of threads saying you should test it and i've heard rumors that the testing proceedure is on cdi's website but i cant find it. i also want to test the kill switch, but i've been told both that it should be grounded when its connected and that it only grounds when you hit the kill switch. can someone confirm which one is true

Hi you can use shrink tubing on the wires . Just unsolder them and shrink tube them , you can get it at home depot . As for the stator testing i would follow a service manual for mercury on that one . Make sure you get one for the year motor and hp of it . I think it will tell you all in it .

By the way I love mercury motors too but i stayed away from them for the cost of the parts for them . the stator coil under the flywheel is like 250.00 dollars and some of the other ignition componets are also expinsive too .
