Ignition Coils for GS425

[JDXC]

One of the ignition coils on a 1979 GS425 I picked up seems to be shot, it's partially melted and reads OL on the multimeter.

After looking around in the forum it seems like folks prefer Dynatek coils as replacements (link attached).

Before I pull the trigger on them, I thought I’d ask:

• What Ohm coils do I need, 3 or 5?
• Should I replace the other while Im at it?
• If so, I imagine I’d need two single tower coils, not one dual tower to replace both?

4-5 ohm for points ignition. 3 ohm is for GS bikes with electronic ignition

In my experience with coils, I prefer the 4.3 ohm coils for electronic ignition due to the sub-par charging systems on the earlier models of GS engines.
I ran into a low voltage issue after installing the new ignition and tried everything.

In my case, I run the Katana style coils.
