Fig. 34 Solenoid resistor terminal identification. Two connector type:

1. Disconnect electrical connector(s) from resistor.
2. Measure resistance between B+ terminal and terminals 10 and 20, Figs. 33 and 34.
3. Meter should read 2-3 ohms for 2 connector resistors or 2.5-3.5 ohms for single connector resistors.
4. If readings are not as specified, resistor is defective.
