How to test

how do i test a distribute pick up ??

Connect a volt/ohm meter to the leads of the pickup and set the meter to 20K. With a heat lamp/gun, heat up the pickup while tapping on the pickup with the handle of a screwdriver. If there’s a change in the resistance while tapping on the pickup, the pickup is defective.

Tester

If the pickup is a magnetic coil, measure the resistance and see if it meets the specified tolerance. If it is Hall effect or optical, the cricuitry has to be powered up and a oscilloscope connected to the signel line. Using an oscilloscope across a magnetic pickup is a good way to verify the amplitude and the lack of noise.

Hope that helps.

You can use a simple test lamp. With one side of the test lamp connected to the negative side of the coil and the other side to ground,if the test lamp flickers,primary switching is occuring,indicating the pickup and module are functioning.
