It does have an internal coil. All the drawings are showing an external coil and different color codes so we are still stymied. There are three wires coming out of the distributor, brown, black & red. These go to a connector block under the built in coil. There are 5 terminals under the connector block. We are trying to figure out what goes where? We think black out of distributor goes to ground, not sure about rest. Couldn't find any good diagrams at mallory or google that match our distributor/coil combo. Wish I could find the harness we lost.
We have the following markings on the cap:
+ which we think goes to ignition hot +
- goes to ground on block
GRD black from distributor
COIL brown from distributor
BATT red from distributor.
Not sure if this is wired right, tried other set ups, they didn't work either.
Grounds are testing OK. Power is coming into +
No spark to plug as we crank it.
Maybe distributor is faulty?
Does it have an internal coil... You may need an external coil.... and resistor... Now you know all I know..... almost nothing...
