In the past I have had heat problems with my Rover engined MGB GT but now solved with ceramic coated exhaust manifolds and secondary pipes, plus beautiful aluminium radiator. The solution was more than adequate as it was running slightly below normal temp - just slightly to the left on the temp gauge. However, in the past few weeks the beauty has had the tendency not to start - massive drains on the battery. Last Tuesday I had to call in the CAA because it would not even splutter (or smell excessively of fuel). Turned into quite a pantomime as the bloke who arrived was not a mechanic - "I just give battery boosts, and tow". But he found the fault much to my shame! The pivot pin had dropped out of the fuel linkage -aaaaauuuughhh! But the saga continues ..... he pressed down on the distributor leads and one needed popping back in. Again shame and I covered my head in sack cloth and ashes. So the car fired first time and ran much smoother (I had put it down to having mild cam). Now we come to the question.... If one cylinder was not firing would the non-ignited fuel cool down the engine a bit, enough to show on the temp gauge ????

They call it a Flame-Thrower. I currently have 2 of them in use, both with distributors converted to Pertronix Ignitor operation. Theses coils put out a bit higher voltage than an original stock coil from the days of the Delco-Remy systems, are not too expensive, and are specifically designed to work with the Pertronix Ignitor conversion. Be sure to order the coil inteneded for 8-cylinder operation. It has a different primary winding resistance than the one intended for 4-cylinder use.

I really do think I remember there were 2 different coils when I was ordering mine for my two 4-cylinder applications. The part number for the ones I have is 40511 and is indicated as having a primary winding resistance of 3.0 ohms. My best recollection is the 8-cylinder version has less, maybe about 1.5 ohms, but I am by no means certain. Just make sure the parts guy who orders for you does his catalog reading, or phone-calling, carefully. I ordered mine through my local NAPA parts house and it was no big deal for them to do the order. I do not know the part number you need.

You could assume that the old coil was correct and measure the primary resistance of that, but having been cooked that may well not be giving the correct readings anyway. However if it still runs the engine it will probably be good enough for checking for a ballast. Turn on the ignition, make sure the points are closed or connect an earth/ground to the points wire (should be the coil -ve), and measure the voltage on the other coil terminal (+ve). If you see battery voltage it is unballasted so you need a 12v coil. If you see significantly less than 12v, typically around 6v with the correct resistances in coil and ballast, then you need a 6v coil. When getting a coil measure the primary resistance, ideally before paying for it! Ignore what it says on the can, the box, or what the salesperson may tell you, labelling can be very confusing if not downright incorrect. A 12v coil should measure about 3 ohms for a standard coil, about 2.4 ohms for a 'sport' coil. A 6v coil should measure about 1.5 ohms for a standard, about 1.2 ohms for a sport. The other thing is that the same amount of heat was being dissipated by the ballast resistance as the coil, so that may have suffered damage as well. The only external visible signs of that would be if the harness wrapping across the front of the car between the headlights shows any signs. Fortunately the ballast wire is spread out along a run of the harness and not concentrated as in the coil, so damage should be less likely. And finally in case you are wondering why the coil gets damaged like this when it doesn't in use, when the engine is running the points are opening and closing and disconnecting the current through the coil for nearly half the time, so there is almost double the heat being generated by the coil (and ballast) when the ignition is left on like this than when the engine is running.

To be truly 1-wire it would have to be self-exciting, i.e. there would be no ignition warning light and no warning of charge failure unless you added a voltmeter. Other than that a North American 73 is pretty straightforward, it just has two wires to the coil - one feeding 12v to the +ve (white)and the other from the -ve (white/black, one of two wires) feeding ignition pulses back to the tach, and one (green/blue) to the temp gauge sender. However you would have to double-check the tach wiring, it changed to the above and a voltage-pulse tach (RVC on the face plate) for the 73 model year but some North American cars seem to have been mis-dated when they were registered and not the model year they were built, so it could have the earlier current-pulse tach (RVI on the face-plate), which is likely not to work with a transplanted engine. The cut-off point is chassis number 294241. The alternator should have two brown wires - one thick and one thinner, plus a brown/yellow for the indicator/excitation. Originally the thick brown was the output and the thinner brown was for the remote sensing of battery voltage. Both go back to the same point on the solenoid, you can either use just the thick brown or use both in parallel for greater current carrying capacity.

I really do think I remember there were 2 different coils when I was ordering mine for my two 4-cylinder applications. The part number for the ones I have is 40511 and is indicated as having a primary winding resistance of 3.0 ohms. My best recollection is the 8-cylinder version has less, maybe about 1.5 ohms, but I am by no means certain. Just make sure the parts guy who orders for you does his catalog reading, or phone-calling, carefully. I ordered mine through my local NAPA parts house and it was no big deal for them to do the order. I do not know the part number you need.
