Crappy Coil
OK I've read several comments about the coil included in the Ultima ignition kit, all bad. After suffering heat stroke on the Xway at 104 degrees when I lost a rear wheel bearing, I don't feel much like being stranded again. I've seen listings for a bunch of no-name single fire coils, along with units from S&S, Crane, Accel, & Dynatec. Any opinions on the most reliable?

I have not heard good things about Accel in recent years. They Used To Be good. Crane went bankrupt and was bought by S&S, so I doubt there is much difference there today. S&S stuff is generally good. Just my opinions.

we have used all of the coils on the market - i just bought an accel for the shops fat boy as was said that crane went under and is now china i am told --
but we just bought a 5 ball bendix from accel and tiwan tedd wont take it back / / it would not slide on the splines of the starter shaft and yes it was china, but the box was made in the USA sooo up to you if you trust what they are outsourcing and what you might think is still made in the USA -- jz

I have run the same set of DynaS Single fire coils for the past 15 years without any issues. I did put them aside for a year when i went over to an Ultima setup - but then swapped back after 6 months when surprise surprise the coil chit itself.

Had the Ultima fail, always had good luck with Accell from the early car days and gave it a try. The Accell coil looked just like the same molding as the Ultima and had a Accell sticker in the box to put on it, don't know if I got a good one but has been fine for several years, I'm hoping I don't jinx myself, hell maybe it was the sticker that was the difference

I use screamin eagle single fire coils because they are basically Harley anyway.

Coils are coils and they have been built for the last 100 years.
The ony dif. between aftermarket and oem coils is the number of sec. windings to provide more current to the plug etc.
The current generation of spark plugs are eons ahead of the older plugs we used to know.
The latest irridium plugs now available require far less voltage than the previous and last as long as the life span of the motor they are installed in !
To check your coil ... coils falter as temp. rises . Coils fail as the connections of the miles of spun small wires in the coil loose connection due to temp. rises. A broken connection in this extreamly tight wind of wires will expand and contract with temps. and produce a open circute as the winding expands.
Check to see if your ok cold but faultering at op. temp.?
