    Main Relay Problem: How do I check for continuity between terminals?

    I found instructions on how to test a main relay at:

    http://autorepair.about.com/cs/troub.../aa010301c.htm

    But how do you check for continuity between terminals? Do you use a test light? Do you clip the aligator clip to one terminal and touch the pointed tip of the test light to the other terminal?

    What do you use to connect a jumper wire to the battery? Do you use wire with an aligator clip on each end to connect the main relay to the battery?

    you need a muitmeter to do a continuity test. I believe it passes a very small amount of current thru the curcuit to tell you if it is connected or not. You can buy one of these for a low as $20 bucks there great for electrical testing on any kind of componets as well as household too.


    I would not pass 12 volts thru it without being sure what you are testing.

    Maybe a small battery( like a AA) and a small light bulb would do the trick in a pinch. Thats 1.5v DC.

    Did you try jumping the relay like in the book states?

    Yes, need multimeter to do electrical testing.... I've seen them as cheep as $5, they're really cheep but would work fine for light use....(I keep one in the trunk so I don't have to worry about my expensive Fluke meter getting heat damage..)
