Read 17+ pages how many ohms should a contactor coil have explanation in PDF format. A shorted motor will read 0 ohms across windings to ground or both. In the case of the above contactor this means coil dissipation goes from 58W open to 13W closed. One terminal should extend to the spark plug housing or boot. Check also: should and how many ohms should a contactor coil have Unlike a circuit breaker a contactor is not intended to interrupt a short circuit current.
OK I checked resistance across the old contactor coil. If you do not get this reading you have a bad coil.

In order to check to see if the relays coil is good or bad one of the best methods is to check its resistance.
Simply remove another coil say the coil from cylinder 6 and swap with the coil from cylinder 3. For example a relay coil may have a resistance of 320 10. The replace was order by PT off the old one. If it is both you will need to replace the compressor. This is most likely to occur under worst case conditions such as creeping along in traffic on a hot day in Arizona this isnt so great for an air cooled engine either. This value will vary between coils but a rule of thumb on MSDs coils would be between 03 - 7 ohms.
