Wiring diagram I need to find a wiring diagram for a coil ballast resister for a 1974 dodge colt 1.6 I know one end goes to the positive side of the coil but do not know where the other end goes.

The wiring of an ignition coil is fairly straightforward as there is only two terminals and regardless of whether there is an electronic distributor or the old fashioned contact breakers, in the basic 12 volt ignition system the wire from the ignition switch is connected to the + or Batt terminal of the coil and the single wire from the distributor connected to the - or CB terminal.

That system became quite rare over time as the ballasted system performed much better for little more cost. The primary resistance of the 12 volt coil is around 3 ohms and the ballast type around 1.5 ohms. It is important the correct coil is used.
You mentioned resistor so it is reasonable to assume it is a ballasted system. In this system one of three types of resistor is used - while many used a length of resistance wire integrated into the wiring harness the AC Delco system used a carbon "pill" type resistor mounted directly on the + coil terminal.
The third type is probably the best and is a ceramic unit with resistance wire inside, usually bracketed on the coil bracket or nearby.

The ballasted system uses a low resistance coil. One end of the resistor is supplied from the ignition switch and the other end is connected to the coil + terminal. There is a third wire directly from the starter solenoid also connected to the + terminal so when the ignition key is turned to crank the engine, battery voltage is supplied to the coil bypassing the resistor and producing a much more powerful spark making starting easier.

By 1986 many vehicles had begun to use either integrated distributors (with the amplifier inside) or a discrete amplifier mounted near the coil. The connections to these is fairly intuitive as multiway connectors take care of most of the wiring though the coil wiring remained basically the same on the + side.

Either a 1.6 Liter 2 barrel carburetor 4cylinder engine with single over head cam found in 76% of that years dodge colts. or it's a 2.0 Liter 2 barrel carburetor 4 cylinder engine with single overhead cam found in 24% of 1974 dodge colts

The ignition circuit should be the same as any 1977 Dodge truck, which is basically battery to ignition switch, start side of switch bypasses ballast resistor and goes directly to coil, run side of switch goes to ballast resistor (on firewall) and then to coil. This is done so that you have full 12 volts to coil when starting thus giving higher voltage to plugs to start, but lower amps, but when running you go through the resistor to get lower volts (about 7) to coil to increase amps for a fatter spark and better fuel economy.

look under hood around firewall follow the ignition coil positive wire to the fire wall you will see ballast resistor.

cant see a listing for a 1996 dakota ballast resistor
if it had one would be a ceramic block close to the old school round coil

this is its coil
there is an ignition coil driver in the wiring diagram

the wires that come from the ignition go on the + terminal of the coil. As most earth wires are plain black I would say the white wire to the + terminal and the black to the distributor

We do not have wiring diagrams here at fixya, the manuals are copyrighted material I did find this one picture with numbered wires that may help you hook things up.

The negative side of the coil goes to ground. The positive side goes to the ballast resistor. The other side of the ballast resistor connects to the ignition switch. More information might be had on manualsonline.com.

if 1 is live and 1 is ground then yes there for your coil
1 side in is hot // other side out is ground or it wont work.

Check the resistance on the coil. the (+) (-) side should be about 10 Ohms resistance and the part that goes out of the coil should be 1-2 ohms resistance. Get yourself an ohmmeter and check it. best way to check is to figure out what wire runs from the computer to the coil and follow the wiring all the way to the coil making sure theres no rips or shorts. If there isnt, then I would splice into the two wires and run two new wires over to the coil. If it still doesnt have spark then its a faulty computer and should be replaced. Good luck
