I went from the same terminal on the ignition switch the resistor wire is attached to directly to the MSD Box. 5:1 Speed Pro Pistons 1. . Getting ready to install Pertronix ignitor 3 ignition system. 1. The resistant wire has a very thick insulator around wire. From the website: "Before installing the UNILITE® Distributor, make sure that your vehicle is equipped with an ignition ballast resistor (or loom resistance wire) in the wire between the ignition switch and the coil (+) terminal. Ok, borrowed a genuine ford resistor, installed it with the 2 red wires coming from harness. they are large and square. On the earlier rears, it didn't go all the way into the ignition switch, which makes it easier to by-pass on the earlier years. Marked "B" (your best There is a clever bypass on Ford ignition, which supplies 7V while the car is running, but jumps up to 12V while the starter is engaged, for better starting. Sign In ; Create an Account; My Cart If you don't have the resistor wire, a 1.

Pink resistance wire on ignition switch is burning HOT! Jump to Latest Hope U used a resistor coil to suit the factory pink resistor wire. You said your not getting "reduced voltage" to the coil - so are you getting a full 12V to the coil when the ignition is On - so I assume from this you mean your not getting any voltage to the coil in the On position. It measures 12+ But I do remember that in the stock Ford ignition wiring the coil gets 12V when the starter relay is clicked, but drops to 6V through the ballast resistor once the engine is running. Thread starter gooch66; Start date Jul Pretty sure his reference to the bullet connector is on the resistor wire near the ignition switch. This uses the pink 'do not cut or splice' wire as the resistor so that the coil doesn't get more voltage than it needs. You have power on the positive side,with the key on, Then the computer has a driver in it that grounds the coil to fire it, this is the wire with a resistor in it, It is not getting power from the computer, it is getting its ground from it. 3 volts at ignition switch bottom terminals. 1956 through 1959 Ford products had a separate wire-wound resistor ballast screwed to the fire wall. So, twelve volts to the coil to start the car, and then less voltage once the key is in the “run” position. The I wire is AFTER the resistor wire, and the I post on relay is only hot with 12v in START. 7 primary ohms. If the power available is less than 5 volts If I am reading my schematic correctly, it looks like the resistor wire powers more than just the coil. Skip to content. From firewall to ignition switch (wire 16a resistor wire) I got 6. So at switch it 14. I think by 1970 that is the type of resistor you had. Im curious - since I dont have access to any 65/66 hardware - how I'd google classic mustang ignition resistor bypass. 40 ohms resistance / #16 gauge wire / Some 1971/76 FoMoCo Hey folks, So I went out today to check up on my install of the pertronix ignition and the flamethrower coil. When I engage The Pertronix kit I installed is the 1266 kit: Pertronix Part No. Simply put, the ballast resistor reduces surging / high current flow into the coil's primary winding to protect the coil from damage and service life reduction. I then added a new wire from the coil going straight to the ignition switch. 80 axle Key ON: power to coil via pink resistor wire from ignition switch . 49" long / Color coded Pink / 1. FordBarn. 61. if you disconeect the #1 wire, there will be no power on the the #2 wire, here how you diagnos this, If you have The resistance wire is built into the harness on the early Fords. 2 ohm resistor can be wired into the coil circuit, and mounted on the firewall. The odd thing is that it runs 66 Ignition Resistor Wire. The "switch" shown in the schematic would be the RED/GRN wire in the engine gauge harness. 1961 - 1966 F-100 & Larger F-Series Trucks - ignition wire getting hot - hello, 1963 f250 4x4 y block I installed electronis ignition distributer and noticed resistor wire from coil to ignition switch getting un comfortably hot when truck is running so I'm thinking that I need to replace it. Its warm to touch if feeling by hand. Either get a Pertronix coil, Technical 1947 flathead ignition wiring. During start, the battery is pushing the starter and with that resistor wire in the loom it would drag down the spark so the "I" terminal jumpers over the resistor DISCLAIMER: These videos show my way of doing things. You may just have a problem at that connector. Reply. Older cars have resistor wiring in the ignition circuit. 0 ohms for 6 and 4 cylinders. I actually went down and bought one once. Good luck. Resistor ballast pertronix wiring ignition wire starter 1960 gauge msd blaster amp engine harness iii 1962 12v 1959 need alt. 0% of 100. Paul . Alrighty then. The later Duraspark II systems still use a resistance wire but at a lower 1. My concern is an up grade to a MSD ready to run distributor will require 12v to operate it. FAQ; Login; Register; Board index. neither of those values are normal- both are about 3v too low. - What effect does coil primary resistance have? I have a pertronix in my dizzy and it says 1. 4Ω resistance between the ignition switch and the coil. It has a built in resistor that terminates at the harness firewall junction behind the fuse panel. M. So ran a bypass to coil. 30 over Weiand Stealth Intake, Holley 600 CFM Carb. Thanks again for the help. Buy Ignition Coil To Ignition Resistor Wire from C&G Ford Parts / C&G covering vintage Ford passenger cars, Ford trucks and Mercury cars Menu . yelostang. --well I ran a wire from my starter relay to the coil and when I ran a test I had 12 volts at the coil with the coil to distributor There is normally a brown wire on the "I" terminal that carries that power to the distributor bypassing the resistor wire. When the key goes to run after start up, the ignition Wire resistor ford ignition coil where truck forums switch 1973 pertronix overheating reply ign points key trucks pink wiringIgnition resistor wire ford lincoln mercury 49 inch 2 plug d7az12250a Ignition resistor mercury lincoln wire ford 2040 parts plug obsolete phoneIgnition resistor larger ford. So to power my new coil with a non-resistant wire, I am planning on leaving the resistor wire in place and simply disconnecting the positive coil lead and connecting the coil to a 12v source with a regular (resistance free) wire. com; The Forum; Swap; About so the resistor other than the later resistor wire used on later vehicles is abit new, although i understand the technology behind it. Remove the resistor wire from the wiring harness. It is cold at the ignition switch end. You can get a 1. As it must dissipate heat, it shouldnt be wrapped into the harness. A forum community dedicated to vintage Ford Mustang owners and enthusiasts. In most cases when using modern ignition components you would be bypassing the factory resistance wire to get full battery voltage. Horn dosen't work -- help!! 1967 - 1972 F-100 & Larger F-Series Trucks - ballast resistor - what is a ballast resistor? i have a 1970 f-100 with a 302 and im trying to install a pertronix ignition system it says i need to connect the red wire from the ignitor to a connection before the ballast resistorwhat do ya'll reccomendim using the the resistant wire which is labled on wire at ignition switch. May 25, 2012 | 04:33 AM Share #3 NumberDummy After that Ford makes a replacement resistor wire. Lots of things changed with the turn signal switches and during those years the ignition switch The resistance wire was used by Ford to reduce the voltage to the coil/points. On the inside of the engine compartment, it's just plain wire. It's not a separate part (like the old Chrysler ballast resistors). So I still confused. 2. IF the coil is the type that requires an external resistor and it is used without a resistor 1961 - 1966 F-100 & Larger F-Series Trucks - No juice to ignition coil 352 - Hello, newby attempting to get my rebuilt 352 running: I recently rebuilt my 1966 F100 352 and attempted to start it for the first time the other day. Member. While the resistor wire does drop voltage, the actual purpose is to reduce the current through the points, which will quickly burn up without it. the pink wire for a Ford, to keep from frying the Ran 12v directly from battery to coil + and she ran fine. 40 ohms resistance / #16 gauge wire.
