resistor?

ok on my 76 anyoen any ideas what the resitor is for by the coil seme sto goto the starter motor?

Its your "Ballast Resistor" old boy …

It gives the coil a full 12volts when you start the car , producing a better spark , as the resistor heats up during running the voltage is lowered slightly . Coil life is then prolonged … …

excelent but oen questioon do i relay need it later cars i.e my y reg dotn seem to have it?

That is because later cars were fitted with the transistorised ignition module which controlled voltage pulses to the coil.

Your typing needs a ballast resistor.

sorry i can't spell very well

i am going to change my set up to  later style dizzy a tci controled one from a 8v cabby so does that mena i can get rid of the coil and lead to starter motor then?

Don't throw that coil out yet! still need one of those.

You need the dizzy and the black bit with wires that sits up in the scuttle (the brain)

As the new dizzy spins it sends a signal to the brain via the hall sender which combines it with some other information, and then sends a signal to the coil etc.

Take lot's of photos of the original setup and compare the two to see exactly what wires you need.

Why do you want to do it anyway? I quite like points, all quaint and temperamental.

lol tempremental

ive got a dizzy and a tci with loom from a later carbed cab so thinking of using this but was thinkign surely i dotn need to use the resistor too

also converting car to twin carbs and early dizzy has twin vacum take off i only need one
