Don't meant to hi-jack, just a question: Do they typically fail like this: all or none, or do they degrade. I am battling a problem on my '99 ACE 1100 where I pick up a good amount of vibration after the engine gets good and hot. I suspect a coil problem, but wonder about the pickup. I am definately firing on both, but may be missing or out of timing on one. (still haven't ruled out carbs yet).tubes_rock said:Do you suspect a problem, or do you just want to test them to verify that they are okay?
Most of the pulse generator issues I've run across only crop up when they are heated. They test fine cold, and fail when hot. This is noticeable when the bike starts and runs fine and then seems to drop a cylinder after 20 minutes.
I have a '99 ACE. The manual stated 480 +- 10%. Do the coils fall in spec for this year, based upon your info? If not, will .2 ohms make a difference in a situation like this?bananabenda said:On the 85-86 vt1100 pulse gens shpuld test at 590-670 ohms at 68 degrees
Your coils are in spec for a 85-86 vt1100.
I think we are down to the mystery (cdi) boxes I have never found anybody that can test these. They do screw up regularly on these earlier bikes.
