Resistance for Ignition Coils

Post by Little Loris »

Does anyone know the recommended resistance/voltage for ignition coils on a ZXR400 H? :smt017 Going to give it a go on the multi meter!

I think 1 & 4 have a weak spark so the resistance should be lower, right? Just wondered what it was so I could use it as a gauge.

why not measure the resistance across both coils, and compare. A duff coil needn't have a low resistance though.

Checked resistance on HT leads and it seems they were slightly corroded and needed a bit of a clean up with some wire wool. After plugging them back in to the coil they seemed to be ok. Resistance was good and had to push them in while srewing in tightly.

Might be a good tip to anyone who has a problem with cylinders not firing rather than go out and buy £50 worth of coil and HT leads! Luckily, I tried this and it saved me a few quid :smt003
