Hey there Budd, Sorry, I was in Pontiac & Camp Dearborn Michigan all weekend just got back and forget now what we originally advised and your specific problem was?? If I recall you converted to 12 volt and used your old 6 volt coil right??? If thats what you did (added a ballast resistor and used the old 6 volt coil), theres a possibility the ballast is a bit too high resistance. Ideally, if it (ballast) matched the DC resistance of your coils primary (between lil + and - terminals) you have a 50 / 50 voltage divider and 6 volts would drop across the ballast leavign 6 across the coil as it was designed for and used prior to your conversion. If the coil measures more like 1.3 to 1.5 ohms and you added 1.8 ohms of ballast, youre not running quite enough voltage and current through the coil. A popular NAPA Ballast is around 1.82 I believe and is used on many coils, but if your particular coil is quite a bit lower in resistance, you may need a less than 1.8 ohm ballast. It would be normal to have more spark energy with the ballast by passed, but you are probably exceedign the max allowable current through the points and coil which causes premature point failure plus over heated coils. If you are running a 6 volt non internally ballsted coil, it should be wired with the terminal leading to the distributor matching what ground system you have i.e wire + of coil to distributor on + grnd or - of coil to distributor if your battery is negative grounded. The output from the ignition switch should be wired to the series ballast and the ballast output then goes to the coil with the coils other terminal to the distributor, is that how you have it wired????? ?? The ballast has to be in series with the circuit from the switch to the coils high (non distributor) side. If the ballast resistance exactly matched the coils primary resistance, with the points closed, there would be 12 volts on the ballast high supply side and 6 volts on the ballast load side (which is the coils input, non distributor side). With the points open and no circuit to conduct current, there would be 12 volts (depending on type and quality of voltmeter) on either side of the ballast or coils input. What are your voltage readings now with the points closed????? ??? If youre seeing a lot less than 6 to the coil (which is what you should see) you may have to use a lower resistance ballast. You say the points and wires and plugs are new?? did you use wire core and not carbon auto suppresor type wire??? Lmme know what you find and e mail [email protected] or call (812) 824-4608 or post back any more questions. Good Luck n God Bless John T Nordhoff in Indiana
