Coil question

[SharkAttackTime]

Hello,
I have another post this full details on my bike issues but I’m just wondering is it possible for a coils to test in rang but still not work? I’m trying to problem solve a weak spark
1971 r60/5 Dyan ignition

What do your coils/wires test for resistance? That would be helpful to know.

[SharkAttackTime]

Guess that would help.
Spark cap to cap 36k ohm
Coil to coil 25k ohm
Coil 1 1.1k ohm
Coil 2 1. k ohm

Talked with a old bmw expert and he thinks it’s the dyna ignition system

[schrader7032]

36k ohms seems high. High resistance will impede current flow, maybe weak spark? Measure resistance of each wire individually. Is there corrosion built up inside the coil towers?

I believe I’m a idiot hahah had someone walk me
Through on how to read the coils they are a little low but should be fine. Looking like it’s the ignition system

[schrader7032]

OK. But for a typical /5, the resistances for the wires/caps are 1K each and each coil is about 20K each. Total around 22K.
