Any way to test coil, ballast or not?
Is there any way to test if I have a Ballast Coil or standard coil.
I have a Intermotor coil fitted but has no markings at all.
I know my system has a ballast wire fitted but don't know if I am using the right coil, having problems starting.

measure the resistance
if you have resistors in series with the coil..
then your resistance of your coil should be very very low like 0,8 ohm i guess

Dood... if you have the wrong coil... as you have explained, then it would not be causing problems starting. A ballast res coil is fed with full
available voltage at start up and it is then cut back through ballest wire during normal running.
In your case, your coil can handle any voltage given at start up, it is when running it would be causing problems.
PS.. i have 2 or 3 ballast coils spare for xflow if u want one?

On a Ford getting ballast wiring wrong will definitely cause starting problems --- easy way to check is run a test with wire from the battery
directly to the coil +ve and see if the engine starts easier.

I've just wired my sierra coil in directly, with a new loom - no mention of ballast.
Should I be worrying whether to have a ballast whatsit or not?? How would I wire it in if I needed one?
The sierra wiring had a black thingy on both sides of the coil, one had a capacitance value on and a bolting point, that I took to be a suppressor and
have wired it in, the other looked like a small black block, with two legs - would this be the ballast?? Surely putting it in series means it would
be there for both starting & running??
Any advice??
By the way, the engine starts & runs fine, though I haven't run it for more than a few minutes

Would i be right in assuming that it is only points based systems that require a ballast resistor, Electronic ignition have higher voltage coil and
no ballast resistor????

Some electronic ignitions have a ballast for example the early Chrysler Alpine FWD, but very few.
