Duraspark Ballast Resistor

The stock 89 Ford/Mustang ignition coil does not need a ballast resistor A simpler HEI ignition that uses the same distributor and fewer parts can be found here. Of course, other situations like a failed fuel pump or even a clogged fuel filter can cause the same symptoms. The other side of the horseshoe connector should go to the Duraspark module. IIRC, the 'resistor' wire is like the fuse-links, a 'spliced-in' wire with different insulation AND a different feel and flexibility and can be found by following positive side wire back from coil terminal. I have no ballast resistor in the system. Re: Duraspark installations You will want a 12v coil if you have bypassed the pink resistor wire. Centech included all parts needed for '66-'77 Some you may not need. Yes definitely it is necessary because when u crank the engine at that time ignition coil is in cold position so at that time complete 12 volts bypasses the ballast resistor but when u releases. Edited by mlpankey - 29 Apr 2010 at 2:38pm. duraspark HEI conversion. Carefully insert a small straight pin in ignition module Black wire. You still don't need a ballast resistor The Ford Duraspark is a VERY nice generic set up for a Pantera, I DEFINITELY AGREE but it is a generic set up. Happy to: "In stock applications, with not one but *TWO* ballast resistors cutting coil input voltage to a ridiculously low 6-8 volts (really better suited for breaker point ignition than breakerless ignition), What's the resistance of "a ballast resistor" then, Bill? Could it not be that the DeLorean actually has "one" resistor made of two halves?. Includes 0. Dura-spark deal. The negative wire to remove the trailing set of points. My particular application was originally a points type application that was upgraded to a duraspark, but it still has the original resistor wire that was used with the points. Ford Ignition Module Wiring Diagram (Oct 05, 2019) - Many thanks for visiting here. Club Car/Yamaha Moto-4 350cc Mixup Thought I might as well attempt to chronicle this as it progresses. The actual change out simply involves removing and unhooking the existing module, remove the existing coil (and ballast resistor if one is present) and then installing the new coil and module with the wires and Molex connector all landing in the same relative positions. Someday I guess I could measure the current waveform on my lab scope using both the duraspark, and TIF modules. I believe the red grommet module also has retard, but I don't have any information on them. You heard wrong. And with a lower R ballast, that should really be higher. Pin 1 hooks between the ignition switch and ballast resistor, pin 2 goes to the negative coil lead, and the pickup is wired to pins 4 and 5. 5 ohm ballast resistor should be used in the run side of the ignition, with no resistor on the start side. The Duraspark distributor is not the best choice for sustained high rpm use even in perfect working condition, its propensity for spark scatter is infamous. I'm replacing the old Lucas "Sports" coil, about 20 years old, on my 351W. The symptoms remind me of a bad ballast resistor in the early 70s Chryslers. I failed to install a ballast resistor on my DSII setup and I kept overheating the coil to the point where the engine would sputter then die. Pins 1 and 2 are the same, and pin 5 is wired to the breaker points, see pic. Centech included all parts needed for '66-'77 Some you may not need. the 12 V to the coil is powered through a low value resistor that in many cases was mounted on the firewall. No ballast resistor needed for either the Duraspark box or the MSD box. The resistor can be by-passed for short periods during short bursts of racing type use but, continuous by-passing will eventually cause some sort of coil overheating. The ballast resistor allows the ignition system to operate at a lower voltage until the engine starts. The ballast resistor in a points ignition limits the average current going through the coil, and prevents a constant DC current (when the ignition is on but the engine is not running) from overheating the coil by dropping the voltage on the coil to 8 or 9 volts or so. In a normal points vehicle. (4) The alignment lug on the Duraspark I coil tower must be removed to allow the Duraspark II horse shoe style coil connector to slide on. Amp Ignition Control Box. The Performance Distributors Dyna-Module has more electronic dwell time in it to give the coil more saturation time to produce a hotter spark. The ballast resistor is usually mounted on the firewall or directly on the coil. I believe the red grommet module also has retard, but I don't have any information on them. After ignition, the alternator begins to recharge the battery, restoring the regular voltage. Ballast resistors match the coil. Ford diagram says 1.

Click to expand "The Mopar system uses the positive temperature coefficient of the ballast resistor to regulate the primary coil current with changes in duty cycle (engine rpm). At any rate, the upgrade has definitely improved idle and power. Each unit is calibrated on a Sun Distributor Machine with a super smooth advance curve to provide instant throttle response, more power and eliminate engine damaging detonation. When running, I have around 6 volts to the primary side of the coil. My DS has been running for a couple months now and is happy with no resistor. Don't add anything. Yes definitely it is necessary because when u crank the engine at that time ignition coil is in cold position so at that time complete 12 volts bypasses the ballast resistor but when u releases. SIDE OF BALLAST RESISTOR”, to the opposite side of the ballast resistor of the Red/white wire and the switched 12v source. 10 ohm resistor. com Forsale Lander. TFI module doesn't. The ballast resistor is in the pink wire feeding coil on the duraspark system and it drops the voltage down to 9 volts. The wires are all color coded the same and the Molex plug is the same. FAST 9000-0015 1. The following tabulation will help you determine which resistor is needed for the various coil / voltage combinations used on early N-Series Ford tractors with the front mount distributor. Same applies to the old points coils for that matter. Another possibility is your regulator is broken and the alternator voltage is too high. If you don't have a ballast resistor to the coil, that could make the module hot (depending on how the module is designed). I forgot to mention it also a ballast resistor also. We have been searching for this picture through net and it originate from reliable resource. We have been searching for this image via on-line and it originate from reliable resource. So I think I will cap off the start input and just use the run input. 66 ohm resistor wire that lowers the voltage seen at the coil when the ignition switch is in the run position and is considered a ballast resistor. with an E-core. Another possibility is your regulator is broken and the alternator voltage is too high. The resistor helps prolong the lifespan of the ignition components. Or if you have a Jeep or a Mopar engine running a ballast resistor ignition, you're giving up ignition power that. In a normal points vehicle. A stock duraspark era coil can suffice, and of course performance oriented aftermarket can be used, too.

I don't have the info in front of me but i know that there are a couple of really good other forums that talk about the ballast resistor, some need it, some don't. FAST 9000-0015 1. I did not install the ballast resistor, now resulting in a fried ignition module. It was used with many early Mopar electronic ignition systems. Anyone running one of these with the blue plastic grommet? (You should know what I’m talking about) So my question is : are you running it with. Incorporates easily found High Energy Ignition (HEI) replacement parts. Combining these two diagrams, that is, replacing the Duraspark Ignition Module with the GM HEI 8-Pin Ignition Module, eliminating the ballast resistor to give the coil 12V at all times, we get the following:. DO NOT reverse the polarity of the RED and BLACK wires - it will destroy the ignition module (and void its warranty)! The Hot-Spark module's red wire connects to positive ( + or 15 on Bosch coil). The dwell control is crude and it relies on a ballast resistor to limit current. The factory fed "E1" from the ignition switch "Start" position rather than the "I" from the solenoid, as you can see it provides the same function. On one side of the resistor you have two wires that are on the same connection. 3L Mustang ignition coil, 1996-98 4. That's where that resistor is--in the harness, under the dash, downstream from the column. If you use the Bypass Connector, use ignition ballast resistors designed for your vehicle s distributor and coil (see diagrams for more information). Happy to: "In stock applications, with not one but *TWO* ballast resistors cutting coil input voltage to a ridiculously low 6-8 volts (really better suited for breaker point ignition than breakerless ignition), What's the resistance of "a ballast resistor" then, Bill? Could it not be that the DeLorean actually has "one" resistor made of two halves?. The HEI controller (really cheap too - carry two spares in the ashtray) controls heating by varying the dwell (15° at idle to 30°+ at revs) so you don't use a ballast resistor. Always crank and pump for 30-45 seconds until she'd light under 40 degrees. Ford diagram says 1. Connect the Red/Green wire to the output side of the ballast resistor. Each unit is calibrated on a Sun Distributor Machine with a super smooth advance curve to provide instant throttle response, more power and eliminate engine damaging detonation.
