Spark problems

Does ne1 have any idea to y i keep burning up ignition coils... and when i do get a new coil it will only last for about 2-3 weeks if i ride everyday!!!! What do i need 2 do?

[86 Quad R]

mind you im no expert on this but oddly enough it sounds as tho it may be that its over amped or the supply voltage is too high.

i'll check the "running" voltage to the coil on a couple of mine this evening and post it to give you something to compare to.

You might try another stator.

Kool another stator... where is that located? and i wuz told that its not suppling enuf, and to get a high output pickup and ignition coil

[Mikeman1]

The stator is located on the left side of the engine under the flywheel.

[86 Quad R]

you have a service manual? if so try en check the specs on each component including the pick up.

[Tazs86beast]

ok.. i willc what happens

I used to burn out coils frequently, until I replaced the CDI unit. Haven't killed a coil since.

When my stator went bad, the ignition would just sputter.

Yeah, I'd suggest replacing the CDI before replacing the stator.

You would need some pretty specialized equipment to test the incoming signal to your coil. It could be done, but you would either need to know a technician with access to that kind of equipment, or it would be rather expensive to have a lab test it. To be honest, it's probably easier and cheaper to just start replacing components until the problem resolves itself. I'd start with the CDI.

But before you did that, I would also go with 86 Quad R's suggestion, it shouldn't cost you much of anything to test the specs, that would certainly be the first step.

Well, the caveat to that is the note in the manuals that says even if the part tests good, it might still be bad.
