Strange either/or spark Force 85

[paul.larson@usbank.com]

Hello Forum - I have a 88 force 85. I replaced one of the ignition coils the other day because I couldn't get it to generate spark from any of the the 3 leads coming from the feeder unit. Now, the two leads for the #1 and #2 each will generate a spark from either the #1 or #2 coils, but when both are hooked up, only one fires....... Is this as simple (expensive) as replacing the #1 CDI box?? I did this experiment with all spark plugs removed from the block. As well, the starter is bogged down so, even with the plugs out, the engine was not turning over at proper starting speed.

Any possibility of swapping the two CDI's, given there's an extra lead on the #2? Or is that asking for trouble. . .

Planning to overhaul the starter as well. FYI.

Thanks for any help.

yes u can swap out the cdi but u most swap the gray-black and black-black stator wires that run in between the top and middle carb.u must pay atention to the cdi wires the red and the 1 orange one.

If your motor won't turn over when the plugs are out then something is wrong.Check all connections and test the battery.Take the starter apart and check it out.
If your motor won't turn fast enough it won't generate spark or will produce weak or intermittent spark.
Get sparkies to test for spark.The holding the plug against the block not good.
Then do a compression test.Poor compression will make it hard to turn over.J
