Note: the following test is quickly and easily run as it does not involve connecting or disconnecting anything. All you have to do is put your butt in the seat and OBSERVE...What does the ammeter read when you turn on the ignition WITHOUT cranking? It should show approx. 4 amps discharge. No discharge? Points are bad, open, or there is an open somewhere else. The points are not likely to be open; the engine almost always comes to rest with them closed. If there is no current flow, old and the others may well be right; Kettering systems like to be started now and again to make sure the surface of the points stays viable. You can perhaps clean them; others can help you better than I with that task. Normal 4 amp discharge? Crank the motor. The ammeter should fluctuate as the points open and then close and the current flow stops and starts again. No fluctuation? The points are not opening for some reason or there is a short somewhere.
