The only meaningful way to check battery voltage with a meter is to discharge the battery enough to dispel the "surface charge". Prefessional testers use a "carbon pile" rheostat for that purpose, while the alternative is to turn on the headlights of the vehicle without the engine running for a few minutes, then turn them off and check the voltage. Any reading that is less than about 6.5 volts indicates that the battery probably is showing evidence of sulfation, a process that gradually affects all common lead-acid types.

Yes you do need a resistor. It will run fine until the points burn up or the coil BLOWS UP as mine did on my 48. The resistor lowers the voltage to around 3.5 to 4 volts. The first signs were systems of vapor lock, and or fuel pump going out. Ran good cold & started acting up when it got warmed up good. The resistor is located on the light circuit breaker & ignition resistor assembly under the dash just under the windshield & directly behind the voltage regulator. It's hard to get to so I mounted my new one on the coil post. Worked great. Previous owner of mine installed new wiring harness & wired around the unit. Hope you read this before bad things happen. Good Luck. 35 Coupe
