Checking the elements

Power Maintenance Relay

1. Check the normally open contact in a non-switching state.

Measure the resistance between pins 3 and 5 of the relay, element side.
Is the registered resistance greater than 10 kΩ? If yes, go to step 2. If not, replace the relay.

2. Check the normally open contact in the switching state.

Using a fused test lead (1 A), connect relay pin 1, cell side, to battery positive.
Using a test lead, connect relay pin 2, cell side, to the negative battery terminal.
Measure the resistance between pins 3 and 5 of the relay, element side.
Is resistance less than 2 ohms registered? If so, the relay is OK. If not, REPLACE the relay.
