1 coil retaining plate marked with coil resistance and voltage.
1 circular spring washer.

REMOVE

  1. Hold the relay firmly with one hand. You may want to use gloves or a clean cloth as the oil from your skin can contribute to a high voltage breakdown. If you need to clean the relay, use 99% isopropyl alcohol or acetone.

  2. For the GH Relays

    • Using a flat blade screwdriver remove the retaining screw located between the coil terminals. Also take care not to bend or damage the coil terminals.

  3. For all others

    • Using a small pliers remove the knurled retaining nut located between the coil terminals. Take care not to damage the tubulation in the center of the knurled nut. Also take care not to bend or damage the coil terminals.

  4. Grab one of the coil terminals with your fingers and pull out the coil.

  5. Turn the relay over to remove the circular spring washer. It will fall out of the coil cavity.

REPLACE

  1. Place the new circular spring washer in the coil cavity with the bends in the washer facing towards the coil.

  2. Taking care that the circular spring washer does not fall out while placing the new coil into the cavity with terminals facing outward from the relay.

  3. Slide the coil retaining plate over the coil terminals. The coil terminals are not polarity sensitive so, orientation of the plate is not important.
