If using this coil with a stock Duraspark ignition, a ballast resistor must be used. 23 ohms for 1978 and later. There are countless aftermarket options available when it comes to ignition but I am limiting the scope of this write-up to the basic ford point system and the ford duraspark system. I switched to Duraspark distributor as soon as I could. Special testers were devised at the time, but the Mar 2, 2011 · Ford started using the ballast resistor wire with the 1960 models. 1956 through 1959 Ford products had a separate wire-wound resistor ballast screwed to the fire wall. The ignition module has the blue plastic insert and was Aug 20, 2007 · I'm running a duraspark ignition module and was wondering how much voltage I should have at the + and - side of the coil with the key on and engine not running?

I'm making my own harness so I dont want to use the factory big plug on the coils. Why would they want the module within Sep 5, 2022 · A blue grommet color designates a DuraSpark II, not DS-I (red grommet high-energy). 71-0. 5 to 1. Taylor Ford Duraspark canister coils have special windings and high voltage output. The Duraspark II ignition system debuted in 1976 with the intent to make substantial increases in secondary voltage and extend system maintenance intervals. Full voltage is applied to coil at start only. When I measure the resistance across the coil I get about 540 ohms which is Apr 15, 2009 · The ignition system can be broken down to following basic parts: spark plug, coil, spark plug wires, distributor, and ignition module or points. Jul 15, 2023 · To add to the confusion, I have seen wiring schematics for the Duraspark system, that shows no resistor at all on the Duraspark 1, and a 1. Run a 12g wire from switched power on relay to a terminal block, and then run a wire from that to the coil and also to the red wire of the duraspark module. Duraspark 2 requires a resister on the coil, but full voltage to the ignition module itself. Apr 4, 2024 · The coil looks new but have you double-checked the primary and secondary for resistance? On your hand-drawn schematic it shows the green wire from the coil to the ign. 0 to 2. More or less, any standard points coil along with the stock fat pink resistor wire under the dash is fine. They do not require ballast resistors and they feature the same style connectors used on Ford Duraspark ignitions. Spec varies by year, and for example Duraspark II coils had a primary resistance of 1. 05-1. Sep 8, 2018 · Most Electronic ignition coils have . Value was 1. May 24, 2013 · the duraspark coil was supplied by a long resistor wire in the factory harness, and needed that resistance to last. Mar 11, 2018 · Summit contradicts itself: Ford Duraspark style. It also went to the wider dist. The lower voltage would cause the module to run at a higher current, and maybe fail the module more often? Sep 5, 2022 · A blue grommet color designates a DuraSpark II, not DS-I (red grommet high-energy). 15 ohms resistance while the TFI E-COIL itself requires no resistance. Sep 5, 2005 · Primary resistance must be 0. 35 ohms nominal, which would provide about 6 volts to the ignition coil during run conditions. 05 - 1. 10 ohm resistance for the Duraspark 2 system. module as 'Not connected". 5 internal resistance. 9.
