Unfortunately, most of the test procedures assume you have either a bad generator OR a bad regulator and are trying to isolate the problem between the two. I have't seen one for testing a regulator when the generator is bad. As I think about the problem, here are some ideas, others posters may be able to confirm or refute.
1) Disconnect both wires between the generator and regulator, leave the "BAT" connection in place.
2) Check resistance between the regulator "F" terminal and ground. On a regulator it should read 0. On a cutout relay it should be between 1 and 2 ohms.
3) Check resistance between the regulator "GEN" and "BAT" terminals. It should show an open circuit.
-- a) Measure voltage at the battery.
-- b) Connect your battery charger to the "GEN" terminal of the regulator, the same as you would normally connect it to the battery and turn it on.
-- c) Measure voltage at the battery and at the "GEN" terminal where the charger is connected.
-- Both readings should be very close to the same and above the battery voltage measured at step 4 a.
Anybody think this makes sense?
