Nick, Relays are about as simple as a stone: a coil of wire to make an electromagnet and a set of movable contacts. If the coil is OK and the contacts are not burned up or welded together, the relay will work. Open the failed relay and take a look at the contacts. If it is an OEM relay, you can bend the metal enclosure and get the relays innards out. If you have an after market plastic housing relay you will need to carefully saw the housing near the base to expose the innards. Let me know what you find .... send me a picture of the contacts if you can. A picture will tell a lot about what happened. The main thing is to keep the main thing the main thing. Do the best you can with what your have where you are. Have fun today! SOBill Nick, Relays are about as simple as a stone: a coil of wire to make an electromagnet and a set of movable contacts.
