Re: Need British Seagull Help-spark not happy

Seahunter guy,
First you must expose the magneto in order to work on it. Remove all coverings. Next check each part, coil, points & capacitor by them selves.
Do you understand & own a meter? First tool required. Check the spark by going to plug wire end, & the other probe to ground. A good coil will read 3 to 4 K ohms on your meter. That winding is first to fail! Next check the capacitor by going to X-1 on the ohm scale & touch each contact point to the probes. It should show infinite if not shorted. BUT remember it is not a full voltage capacity test. Next check the points by removing them from the motor & cleaning & dressing up the contact surfaces. Check with paper between the contact surfaces to again see an infinite reading. An infinite reading will be on the side of the meter scale & looks like an eight numeral laid down sideways on the end of the scale using an analog meter. with points closed it should read no resistance to function correctly.
Next clean all the magneto parts clean enough to eat off of. Contamination is conductive with high voltage.
Please report findings to correct failed components. Doing a visual check will result in failure. A electrical devise requires electrical instrumentation to trouble test.
Good luck
