Question
Hi,
I am trying to start a 1948 Pontiac that has been sitting outside for years. I've replaced the coil, points, rotor, cap, condenser, spark plugs and wires. Put in a new 8 volt battery. I am getting no spark at the points. It is negative ground.
Any ideas?
Thanks, Mike
Answer
Since you have made the move to the 8 volt battery you will need to take one of two paths, either return the battery or change the charging system and ignition system to 8 volts. The added voltage will not allow the voltage regulator to function properly and the generator will not charge an 8 volt battery. The added voltage will fry the ignition points in short order. 8 volt batteries are NOT a direct replacement for a 6 volt battery.
Let me know which path you are going to take and we will go from there.
Brad
