RE: You've got the wrong ballast resistor.
By Barry B - 07/31/2001 6:52:00 PM; IP 134.217.237.30
Shoe’s right, a high output coil has lower resistance windings. You need a lower resistance ballast to match the coil and develop the proper voltage drop, the two components are in series and make a voltage divider. The resistance wire in Ford point-type and early Duraspark systems specs. out between 1.30 and 1.40 ohms. The Duraspark II systems with the high output coil used a resistance wire between 1.05 to 1.15 ohms. Same holds true for the condenser, its capacity is matched to the coil.
This thread, so far...
