Checking the elements

Power Maintenance Relay

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

Measure the resistance between pins 3 and 5 of the relay, on the element side.
Is the resistance registered greater than 10 kOhm? If yes, go to step 2. If no, replace the relay.

Is the resistance registered greater than 10 kOhm? If yes, go to step 2. If no, replace the relay.

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

Using a 1 Amp fused test lead, connect relay pin 1, cell side, to the positive battery terminal.
Using a test lead, connect pin 2 of the relay, on the cell side, to the negative terminal of the battery.
Measure the resistance between pins 3 and 5 of the relay, on the element side.
Is the resistance registered less than 2 ohms? If yes, the relay is OK. If no, REPLACE the relay.
