SOURCE: Re fitting a Bosch GT40R-T ignition coil to a Ford V8

The ballast resistor only weekens the power to the contact points while the engine is starting after that the secondary wiring "is" a built in resistor. I suggest you use the ballast or you'll be changing a lot of point sets.Just out of curiousity, why would you want to convert back to an older and proven obsolete type system?

How to wire an ignition switch to starter solonoid on a 1977 Chevrolet van/ 350 cid?


Can't remember what year they changed to coils with internal ballast resistor, but circuit is the same for those except extra wire from starter to coil + is eliminated on those and resistor wire from switch to coil becomes just a normal wire. Hope this helps.

I'm trying to find an ignition wiring diagram for my 1977 dodge melmar fargo f40 rv


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.

Ignition ballast resistor is usually mounted on the firewall near the back of the engine. It's white, rectangular, and has a wire connector on each end. It's function is to limit primary coil current during engine running. The ballast is bypassed during starting so you get a higher spark voltage. If you remove the ballast, you will burn out your coil.

Where is the ballast resistor located on a 1996 dodge dakota


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

I am trying to get spark to fire the motor in my dodge raider. The ballast resistor and coil had all the wires disconnected. Where do the wires connect back too?


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.

I am restoring a 1984 BMW 323i model E30. I am replacing the Bosch main wiring loom with a Siemans wiring loom. I plan to use the original bosch engine wiring loom and connect it to the multi-plug of the...


your asking me something now ,havent seen one in years but the cables can be connected over with time and patience and a bit of solder is good as it doesnt corrode ,now the ballast resistor fitted with the siemans was a different type of circuit and as it was a bosch then wire it as the bosch was wired ,because the ballast resistor was used in conjuction with a 9v coil and when you cranked the engine it allowed full 12v voltage to the coil to give an increased spark under crank load ,never did work that well to be honest and the resistors often packed up so use it as the bosch system .On the siemans you had a wire from starter connection on ignition switch to coil and the ignition feed went through the resistor to the coil ,Simple enough but them resistors were a right pain in all honesty

I have to hold the ignition over to keep my 91 jeep running


This is normally a problem with the ballast resistor or associated wiring.
On some vehicles, in order to give a stronger spark during starting, which helps the engine to start, the ignition coil is designed to run normally on about 9 volts. As a car's electrical system runs on 12 volts, a ballast resistor is included in the coil's electrical connection to "drop" the 3 volt differnece. When the key is turned to the start position, the full 12 volts is applied to the coil for as long as the engine takes to start (giving a much stronger spark), and when the key is released back to the normal "on" position, the ballast resistor is automatically switched in to the coil circuit - if the coil was over-run on 12 volts all the time it would soon burn out.

Depending on your skills, and whether you have access to a tech manual or not, this isnt too difficult to fix. Otherwise a small independant garage shouldnt charge too much to fix this sort of probelm.

Turns over but won't start


Is the rotor turning in the distributor? If so, most likely the problem is in the madnetic pickup in the distributor. If not, pull the distributor out and see if the gear on the shaft is broken. A good gear on the distributor and the distributor not turning means you need a timing chain!!!
