How to Troubleshoot Problems With No Fire to the Points on a Massey Ferguson 175
There were only two engines available for the Massey Ferguson 175 over the span of the 11-year production run of this model. Both engines are 4-cylinder motors, one a diesel and the other gasoline powered. Only the latter has an ignition system, naturally. Troubleshooting a breaker point ignition system is a straightforward task, but all components involved must function correctly to deliver voltage where and when its needed.

Set the multi-meter to the voltage scale that registers 0 to 20 volts. Check the voltage at the battery terminals. Charge the battery if the voltage is less than 12.5 volts. Clean the battery cable connections if any corrosion is present.
2Turn the ignition switch to the run position. Measure the voltage at the primary side of the ignition coil. Replace the ignition switch or connecting wires if no voltage is present at the primary terminal of the ignition coil.
3Measure the resistance of the primary ignition coil windings. Turn the ignition switch off and set the multi-meter to the lowest ohm scale. Place the tester leads on both ignition coil terminals. Replace the coil if resistance exceeds 5 ohms.
4Replace the breaker points if they appear corroded or pitted. Replace the condenser, if no faults are found elsewhere. You can test the condenser with the proper equipment, but the cost of a new one is minimal.
