Electronic ignition questions

Would not use a coil having less than 3 ohms resistance with a Dyna-S ignition.

Stock coils on models with Kawasaki electronic ignition are often less than 3 ohms.

Good Fortune!

thank you patton! that's what i was looking for

Going too low on ohms will allow higher current which can damage things (like the Dyna S says to use no lower than 3 ohm), if you go too high you can end up with a weak spark due to having too much resistance in the circuit, but it's not necessarily going to outright break anything. I think the stock Kawasaki's are 2 ohms on a lot of models, so with the stck system you'd probably be fine there.

I figure if replacing, go with 3's, just because you'll be fine with either the stock or dyna s system down the road.

As Del and Patton said, you don't want to go lower than 3 ohms on the Dyna S.

Most of the factory electronic ignition systems used 2.3 ohm (but usually measure higher, like 2.5 to 2.7).

The factory points coils, which is what your bike would have come with, had 4 ohms.

so this could cause a problem with my electrical system correct? i mean if i have a point system and im using 2ohm coils when i should have 4ohm coil, which would allow a higher current, could burn up something? correct? causing my bike to not run right?

my charging system seems week i really hope the regulator rectifier isnt burnt. :sick:

this sounds contradicting. im confused, wait ok so you're saying the coils i have currently, the (4cyl) coils are most likely 2 ohms, but my stock kz750 twin coils(if i had them) would be 4ohms? correct?

Here's how to troubleshoot the charging system:

YES. You will fry the coil and maybe some wiring.

Yes, the stock 750 twin with points used a 4 Ohm coil which would work fine with your Dyna ignition.

thank you guys, this would probably explain why the condensor that was in it that looked brand new was not working..... you guys have been much help. I will try to find a higher resistance coil until i find a fair price on a dyna 3 ohm.

I doubt you can beat www.z1enterprises.com for Dyna coil costs.

Z1 sells four Ohm EMGO coils with wires for $36 each.

I've been running one for 6 years and it works great.
