Bike just won't start...

You say one coil, that worries me, your '87 should have 2 pickup coils, not one.
Not all FJ1200's are the same....the later '89 models used one pick up coil with a different rotor with a Digital Ignition Control box.
These will not work with your '87. You have a different ignition box, a Transistor Controlled Ignition box.
Your pick up coils and rotor should look like this: https://www.partzilla.com/catalog/yamaha/motorcycle/1987/fj1200t/pickup-coil-governor

That is the coil and rotor I replaced. What I am replacing now is the ignition coils, which probably burnt up when I played it down...

Pat Conlon

Ok, good, if your parts match the picture, you got the correct pick up coils and rotor.

Let us know how it works out.

Where do I test the pick-up coil at?

At the plug to the ignition box. Unplug the lead to the pick up coils. The plug has 3 male prongs. The black wire is the common ground. Test the ohm values between each prong and the prong with the black wire.
See my #24 post above for ohm values.

Very easy. The $15 cost of a multi tester is much less than the cost of a set of ignition coils.

It was in eastern Oregon, where they use pumice pellets to melt snow and create traction for cars in snow. When the sun comes out it exposes little piles of pellets in intersections and the shoulder. When I avoided him I hit a pellet patch... My bike literally disappeared from beneath me... Strait to pavement... My back tire has probably 1500 miles on it.
Well, that's different. From your original post, it sounded like you intentionally laid your bike down. Yep, it's amazing how fast a bike can disappear from under you when you hit the marbles. Been there, done that.   :wacko3:  But just for the sake of discussion, I will suggest that perhaps you were too close to the car. Always give yourself enough room so that if they do something stupid, the car won't hit you. Sometimes easier said than done, I know...

As for your bike's no-start problem, if you can't get it figured out, I can scan the trouble-shooting guide from the FSM and send it to you.

Thanks a lot Bill, if you could send it over anyways I would appreciate it. I have the other ignition coils installed. Just letting it sit on the trickle charge for a bit. I wasn't close to the car... He wasn't even in the turning lane  :Facepalm:

FJ_Hooligan

Unfortunately, you've already proven that new coils will NOT fix your problem.

How do you burn up a coil as a result of laying the bike down?  I can't recall anyone ever having that happen.

David, he hasn't tried them yet....let's see...

Ryankhitt

Well, you may be right. I still have same problem. I turn it over and nothing happens except on big back fire

Ryankhitt

The shop said it is possible to burn up ignition coils if you lay it over and the key is in the on position...???

Ryankhitt

This is the tester I have. How do I test it on the pick-coil?

Ryankhitt

I just turned my key to the ON position and got a backfire as soon as I turned the key.
