This is why the Dynatek misses

Been talking to MSD about getting a coil from them to sell instead of the Dynatek. Kinda like someone said, no need in giving them more money.

At his request I took some ohm readings on coils. I only have a 09 now but measured the coils and got a resistance reading of about 2ohms.

Had a Rhino coil from Dynatek and it states .5ohm but it was .9ohm.

So I asked why would it miss. His answer was, the coil driver in the ignition was not strong enough for the stock coil and would be for their coil which has much less resistance. This it can't charge up the coil high enough or quick enough.

I said, shouldn't they have checked that? He said yes but they may have had a Teryx they tested on with a coil with less resistance.

I want to get a coil from MSD to fix this and be less money than the Dyna.

I need help though since I sold my 08.

Someone take a multi-meter and measure the voltage on the two connectors on the coil when you turn the key on but don't start it, just turn key on.

If it measures no voltage then it is a true CDI, if it does measure 12v it is a inductive style. Each one would get a different coil, actually one for a inductive works on both and one for a CDI won't work on a inductive or the other way around.

Please let me know.

Todd, I just checked mine at the coil on the rear cylinder side (working on my clutch) and I got NO DC voltage on the leads coming into the coil. Did I measure at the right spot? You can give me a call on my cell at 951-634-1986

Jim

PS I got .4 ohms on my coil

You measured right on voltage.

Did you measure in same place for ohms?

Maybe we need to get several people to measure the resistance on their coils and see if the differences might be the issue.

Anyone with a multi-meter measure the resistance across the leads on one or both of your coils and report back.

I checked mine tonight before I read this. I had 1.6 ohms on the meter. I did not check voltage with the meter. This is strange.. I was on Summits web tonight and they have about 20 pages of coils. I found one that put out about 60K volts, and had about the same resistance. But I dont know if it would charge fast enough.. I will check the voltage tomorrow.

I was just going to order those coils tonight, I will hold off to see if a better coil can be found.

The resistance seems to be the issue. Maybe Dynatek is not really at fault. If their Teryx had a .4 ohm coil and the next one had a 1.4ohm then they assumed they all were like that.

Please more people check theirs and report back.

Remember 08 model only.

Todd

I think you should measure the resistance with the coils, unpluged from the primary and secondary. This will give you a true reading.

Todd, yes I measured the same place at the coils for the ohms rating...

And before you ask? Yes I unplugged the leads and then checked ohm rating...I also reversed the leads and checked the ohms again on the discharge cycle...same rating...started at .3 then leveled out at .4...

PS I just checked the other coil...same thing...no voltage...well a leak voltage of .002...and .4 ohms...

I'll try to call ACCEL Ignition on Friday. I used to work there (on their DFI fuel injection), and I'll see if I can get the right coil for the Teryx.

Just checked mine...

Front coil had 0.2 ohms
Rear coil had 0.1 ohms

Both coils had 0 volts
