Hot ignition coil 140-160

Here some info from another person with this problem on another type vehicle.

I would check / replace the points if you are not running a perlux/pertronix or other aftermarket rig.

1. Normally the coil is mounted upside down. Being oil filled (to cool it) sometimes oil may leak out, reducing its cooling efficiency.

2. If you turn ignition on but don't start engine, if the ignition points are closed then the coil will heat up very quickly (and ignition points may burn, too)

3. If points gap too small (dwell angle large) then the coil is being energised longer than normal - result warm/hot coil.

4. Ignition coil should be 3 Ohms resistance across small terminals (check with multimeter, ignition off, and wires disconnected from terminals). A resistor type coil would read 1.5 Ohms. Without the a resistor wired in series, the 1.5 Ohm coil would get very hot.
