4.5.1 Checking the SCR Module
The procedure for checking the SCR module is as follows:
1. Disconnect the wiring going to the module.
2. Using an ohmmeter, the three main terminals (A1K2, K1, A2) you should read high resistance in both
directions on your meter.
3. Gate (G1) should read a high resistance between the top (A1K2), bottom (A2) terminals and a low resistance
(10 Ohm - 40 Ohm) to the middle (K1) terminal.
4. Gate (G2) should read a high resistance between the middle (K1) and (A2) terminal and a low resistance
between terminal (A1K2).
NOTE: A wiring diagram of the module is located on the side of the component.
