i need some help on how to test the pick up coil

it is in a Delco Remy Distributor

It is in a Chevy, 350hp  

I do not know exactly why you want to test the pick up coil but as far as I know it is either good or bad and the car or truck would not start if it is bad because it would lose fire..  

you need a digital volt meter....

set it for ohms..  look for the reading to be between 500 and 1,500 ohms...

then if the shaft is in .. set the volt meter to 2 volt ac and spin the shaft...  you should see over 1.0 volts ac... when you turn the shaft...

if it is a small cap gm later model dizzy.. look at the sandwitched reluctor for cracks in the magnet... that will cause drivability problems...

for those ford and mopar owners.. this is a really important test when the ignition fails to spark...  as the sintered metal the slide on reluctor fails to hold a magnetic field for a long enough time to cause a signwave output from the pickup coil...

if the pickcoil does not put out enough a/c voltage,  the power transister in the module will not turn on to pull the coil ( -)  to ground and allow it to saturate the primary windings..
