Simpson Type Electronic Forward Reversing Module
by Paul Pittard
Test Procedure for modules with wire leads
To Test Agitation
1. Remove Wires EA, CA and CB.
2. Disconnect Cord Active from timer
3. Connect Cord Active to EA on the EFR Module
4. Connect CA to Neutral (this gives normal agitation)
5. Make all wires safe and turn on the power. (Normal agitation should be observed)
6. Turn Off Power
7. Remove CA from Neutral
8. Connect CB to Neutral (this gives gentle Agitation)
9. Make all wires safe and power on (gentle agitation should be observed)
To Test Spin Motor action
1. Leave EA connected to Cord active and CB connected to neutral
2. Connect CA to neutral as well
3. Make all wires safe and turn on power (single direction agitator rotation should be observed.) Note: Spin does not occur as clutch solenoid (or brake motor) is not energised
4. Reconnect wires to original positions
Later Modules with male terminals
The agitation function is similar to described above, these modules do not have a CB terminal, and active for spin is supplied direct from a timer switch. On the late modules, if CA is connected to Neutral it gives normal agitation. If CA is open circuit, it gives gentle agitation.
