rev3 coil resistance values.

Recommended Posts

Hi....Can't seem to find a definitive answer on ignition coil resistance values for the rev3. seen 3 & 10000 ohms quoted but also saw a test for a leonelli coil suggesting 0.6 & 11k. Testing mine I'm getting 0.6 ohms on the primary and 4,500 ohms on the secondary. Can anyone tell me if this is out of spec? Thanks in advance.

Just had my stator rewound thanks. It's actually the HT coil I'm now looking at. I'm pretty sure its bad but was hoping someone could confirm.

Are you measuring the secondary with or without the resistor cap (which is typicality about 5000 ohms)?

Resistance reading don't tell the whole story. https://www.trialscentral.com/forums/topic/70835-montesa-cota-315r-no-spark-issue/

CDI ignition coils are fairly universal - a better way to test the coil is by substituting it into a working bike (almost any single with a CDI).

I'm measuring without the plug cap. I found a crack in the plastic case, thought about an epoxy patch and then just decided to order a new one. Nobody close by I could borrow a coil from. Cheers.
