nuguy..... ...ah yes, the mysterious resistor, you can't see 'nuttin' and all it does is gitt HOT. Since you are asking about your 12-to-6 volt converting resistor and you want to measure the voltage drop across the resistor, wannna bett you read 6-volts??? Why? Its the LAW, Kirchoff's Law. BUT that only applies when the ignition points are CLOSED so that you have a complete circuit. What happens to the other 6-volts? It gitts dropped across the 6-volt ignition coil. Isn't that amazing? 6 + 6 = 12, everything is accounted for just like the LAW sez. BUT that ONLY shows on yer meter when the engine is NOT RUNNING. What happens when the points are OPEN? 'nuttin', thats what. Why? 'cuz your circuit is OPEN and nothing is exactly what you will read across yer 12-to-6 volt converting resistor. ZERO volts. Its the LAW. Running engine is on/off...on/off ...etc... and yer meter is so dumb it don't know that and so it kinda averages the on-volts and off-volts and who knows what that number is. And digital meters are also susceptible to ignition noise which also reduces the accuracy of the reading. Its all TECHNICAL stuff. HOWSOMEVERS: do yerself a BIG favor and DITCH yer 6-volt coil and 12-to-6 volt converting resistor and SQUANDER $15 for an honest-to-goodness real 12-volt coil that uses NO RESISTOR. You will simplify yer wiring, and gitt HOTTER SPARKIES too. Isn't that amazing?..... .respectfully, Dell, yer self-appointed sparkie-meister
