The symptom of 12 volts at both sides = is normal. The coil is just a bunch of wire and if there is no ground = on the other side, the voltage will pass through. The ground is supplied = by the ignition module when it wants to fire the plugs. Obvioulsy that = will only happen when the engine is turning over. The module gets its signal = from the hall unit in the distributer. You don't say what year so I'm = assuming it is electronic, but if not, the points do the same job directly. = The low reading on the the coil is also normal. Usually only a few = ohms. A good multimeter should tell the difference comparing when you short the = test leads and then when you check the coil reading. I could go through an = extensive explanation of further testing, but a manual (even borowed) would help = you a great deal in the long run. One simple test that you could do is = to have someone turn over the motor while you have a 12v light connected across = the leads on the coil. I should blink if the circuit is good to that = point. Use a small bulb if possible or a standard test probe if you have = one. Not a brake light bulb, they are too heavy and you might not see the blink. = If no blinky, then look at the connections for the distributer and the = ignition module (grounds also). Sorry this is not much to go on. Good luck =
