Hi All

Have a 1984 Yamaha DT 125 which I am trying to repair.

I have been testing coil via this procedure.

DMM to ohm range.

Primary side. Probe on negative and other probe on positive. Gets a ohm reading of 1.3 ohms. Gets a literal continuity sound.

Secondary side. Probe on negative and other probe on end of plug wire. Gets a ohm reading of 3710 ohms or 3.71 kilo-ohms. Continuity no sound but 887 reading from DMM

Do anybody perhaps know the correct resistance/ohm values

Am I doing correct testing method.

Please help

Thank you

Gasant
