I've got a 5ohm Dyna coil kit ready to connect. Do I still use the ballast resistors?
thanks

Fitting Dyna coils to 900SS with Bosch ignition
G'day Pete,
We have just fitted a set of 5 ohm Dyna coils to a 78 SS with good results so far.
As far as the Ballast resistors go, we were told they were not needed, so have done away with them. Some body with much more knowledge than me may like to chip in as to why, but all good thus far.
The hardest part was fabricating a new bracket, as the Dyna's were a little bit bigger than the OEM coils, and as such did not fit the original bracket.
Cheers Rick

I have desmo disease, I just hope they never find a cure !!!

I'm wondering - when your 3 ohm coils burnt out, did you then go to 5 ohm coils?
If not, curious as to why not? Is there an advantage to using 3 ohm coils with the ballast over the 5 ohm?

Hi Mitch, yes as the product info says, remove the ballast on your bike when you fit those coils. Also, everyone else note that for the stock bosch pickups etc, 5 ohm coils works best on all street applications period. If you are going to install on a race bike and are willing to mount the coils lower and out in the wind so they can cool, then you can use 3 ohm coils without the ballast and not have any problems. If you install 3 ohm coils in the stock place or anywhere up under the tank etc where they will not get any wind they will self destruct due to heat very quickly.
The coil mount brackets that we stock will save heaps of time over fabricating something to mount your coils although they will most likely still need further modification to fit your specific application.
By the way, I shipped your shocks out yesterday Mitch you should get them today or tomorrow.
