davek_14 Posted February 20 Report Share Posted February 20 Looking for a part number for a 1.6 /1.9 ohm ignition coil to suit electronic distributor. The distributor cap and leads for the 7K are very expensive, have a standard cap off a 5K that fits, so need to match it with a suitable coil. Can anyone help.

Banjo Posted February 21 Report Share Posted February 21 Hi Dave, A Pertronix sports coil with a 1.5 ohm primary winding are available on ebay for a bit over $ 100, ex Adelaide. The 5K dizzy is an electronic distributor, with a built-in ignitor. However, the ignitor, has a limit to what the minimum resistance of the primary winding, can be. My Yellow Toyota Bible does, not give specs for the coil for the 5K. It suggests coils with primary resistances of 1.3 - 1.6 ohms, or 1.5 - 1.9 ohm, for a dizzy with points. Electronic ignitors could probably go a little bit lower, but you would run the risk of maybe damaging the 5K on-board ignitor. A 1.5 ohm primary coil, sounds like a good compromise.
