Hi all
I have a dilemma with my ignition coil.
A couple of weeks ago, my coil packed in and I thought it was a good opportunity to upgrade to a Flamethrower coil. I am running a 260Z with the E12-80 280ZX electronic distributor. I couldn't see what the resistance was on the old coil but I know it didn't have a ballast resistor attached. Couldn't get a reading on it when I tested it.
All the indications from reading and the advice given was leaning towards a 3 ohm coil so I bought one. However, I fitted it and the car turned over and over before eventually starting and then ran like a dog - coughing and spluttering. All the wires were checked along with the spark plug gaps & all fine. Tested the coil resistance with a multimeter and it showed 3 ohms.
Luckily I had borrowed an OEM Nissan 280ZX coil off Huw to get me to JDM day at Combe whilst I was awaiting delivery of the Flamethrower and the car started & ran great off that. Tested it and it was 1.5ohms. Again no ballast resistor was used.
Question is, do I persevere with what should be the correct 3ohm coil and if so should I be setting anything on the engine to compensate or do I return it and go with a 1.5 ohm coil? Would it wreck the electronics on the dizzy by doing so?
