Am I reading this right?

Hi all,

6V positive ground system. Trying to determine if resistor is dropping voltage right.

Using a multimeter, I place the positive lead on the battery positive (ground), and touch the other lead to resistor from ignition, 6.2V, and resistor on coil side...I'm still getting 6.2V...should I be seeing 3-4 volts, or is my method wrong?

Thanks!

Bingo! My dear ol' 2N quit just as if someone turned the key off. I was figuring that a resistor will "resist" no matter if there is a load through it.

Anyway, turned the engine and voltage never dropped....with your help I quickly discovered I had a bad (new) condensor. Put the "old" one back in and it not only started but ran much smoother.

Thanks!

Randy2,

"Anyway, turned the engine and voltage never dropped....with your help I quickly discovered I had a bad (new) condensor. Put the "old" one back in and it not only started but ran much smoother."

The Condensor would not cause your points to not close (voltage drop) You most likey had a bad connection between the Coil Pigtail Spring and the Concave Screw Head or some other "open" Circuit.

Hope This Helps,

Yep.. like rob says.. as long as the circuit is open ( points open ) there is no current flow.. without current flow there is no voltage drop across components. Check them with points closed.

Bump the starter to open/close the points and watch for the voltage change.
