Doesnt the lean burn use a ballast? If it's a 4 pin ballast, the half that's hooked to the coil is same
EXAMPLE:
Let's say you have a Mopar electronic ignition and the box or the dist. goes bad. You can actually unplug the box, drop in a points distributor, and hook the dist wire right up to the coil NEG and start it right up.
Could be wrong, don't think "that part" of the lean burn is different.
You can confirm this by doing following:
Turn the key to run with all the original components connected. Put a meter on the coil POS post, and for good measure, jumper the coil NEG post to ground. If it has a resistor, the voltage will be considerably below battery voltage, perhaps 6-8V
