Need Help with 600 series Ignition

Here are symptoms: No spark (can hold in hand!) from coil AND the external resitor gets very hot when key is on.

I followed all troubleshooting offered by John T, old and others (thanks to all!) but no good.

More facts and symptoms: 12 v. coil with external resistor,
5.8 v. at the coil's + terminal (top side, away from distrib),
COMPLETEly checked points, condenser, all seems ok,
new points, condenser, coil, resistor, coil wire,
1.3 Ohm across resister,
1.4 Ohm across + and - of coil,
points set at 0.024,
good ground wire and connections from the - of coil,

So, out of ideas and still no coil spark and the Resister is HOT!

I much appreciate any help, insight and ideas anyone can share.

Gotta mow while it's dry! Best to all.

If the test light stays on continuosly, the points aren't making good enough contact to ground the circuit, or you have an "open" in the circuit in the distributor (bad points, broken connector link...)

If the test light doesn't come on at all, you're not getting current through the coil, or the circuit is just plain grounded inside the distributor (such as points shorted to ground..)

Hope this may help...

Love this Board!!

Still.. I'd replace/clean/file the points and check again.. if the resistor is getting hot.. current is flowing. If you are getting voltage to the coil primary.. then there are no shorts befor ehte coil. Check distrib feedthru wire/insulator.. they get brittle and crack, and short out.

I remember that I had no spark at all when I opened the points with screwdriver. However, I'll check again tomorrow.

Many thanks,

Thanks to the discussion on this board I was pointed in the right direction. Man, I have learned a lot. Many thanks to all who responded.

Now, I'm off to mow.
