resistors,reducers and other nonsense

Since the nominal resistance of the "infamous ballast resistor" is about 1.3 ohms at ambiant tempature and since your Chrysler BR is 1.2 ohms, and since most 12 to 6 volt converting resistors are about 1.5 ohms. your cutting your E applied by twice. Ya gotts an extra resistor somewheres. FIND IT, just for your peace of mind. (and I'll bet you'll find that it is the OEM ballast resistor mounted to the back of the dashpanel)

Bottom line, 3.2-3.5 volts at the frontmount coil terminal is the desired voltage. Use eather the OEM ballast resistor OR the Chrysler BR but NOT BOTH.

As for the voltage drop "across" your 12 to 6 volt resistor, you'll get NO DROP until the series circuit is completed by closing the ignition points.

Series resistors are like flashlight batterys, doesn't matter which one goes first but the light doesn't work untill the switch is closed. I generally put the 12 to 6 volt converting resistor between the ignition switch ON terminal and the ballast resistor's former ignition switch terminal.

Oh yeah, check your ignition switch voltages, both sides against ground. Should be same voltage when turned on. Lotta ignition switches get gunked up internal contacts and you'll loose 1-2 volts, not good.

As for your drained battery, not uncommon to miss-wire and drain battery, specially if ammeter doesn't show amps. Infact, your daily driver, if left parked for about 1 month will drain its battery thru your idiot light and you won't see a thing. Since you start your daily driver every day, you fully recharge your battery mini-drain and never notice it..... ....respectfully, Dell

Since you claim to know where all the resistors are, you're missing one somewhere (according to the voltage numbers you've supplied) check for BAD IGNITION SWITCH internal contacts.

Also of note, if your ignition coil is "weak", thats usually a sign of shorted primary coil windings which reduce the coil resistance and will lower the coil terminal voltage. (you report 2 volts) By upping the coil voltage (3.5 volts) by reducing the "before the coil" resistance, you are increasing the current thru the coil and POINTS and can burn out the points quickly.

Ignition coil primary winding shorts out because of overheating and melting the insulative tar by originally supplying too much volts (which increases the amps) at the coil terminal.

If you charged a 12 volt battery for 6 hrs at 10 amps, you've probably got a bad battery. Take it into a real battery store for a "free check"..... ....Dell
