How to Test a 12 Volt Coil?

Answer

You can test the tolerance of a 12 volts coil using a multi-meter. Set the tester to ohms resistance reading and place the test prods to both ends of the coil, see if the resistance is within the coils functional level. Find more methods of testing from this site. how-to.ask.com

1 Additional Answer
To test a 12 volt coil, you need to disconnect the power to it. Then set a multimeter to the ohms setting, then read across the posts. The ohms resistance reading should be within the manufacturer's tolerance for the coil.
