Coils... ignition not spring...

What happens if you run a 'ballast' coil on an un-ballasted system?

[Adrian Southgate]

More to the point is it just that little square component from the low tension circuit that makes the difference?

[28ullkq4hau58]

the little square thing sounds like the ballest resistor  a photo will help i.d. it

[Big Vern]

Nope thats a suppressor

[28ullkq4hau58]

it go,s pop,,

Old BL stuff used to have ballast resistors on, if you don;t need it just by-pass it.

[Big Vern]

Ballast coil will overheat as its designed to give the correct high tension at 8v input. Ford ballast resistors used to be wire type while BL used the ally or ceramic heatsink type.

use a voltmeter to track down the ballast resistor and by-pass it or buy a 'normal' coil.

I had this happen, car runs but misses and back fires on acceleration lack of power to. The mk 2 escort loom as a ballest wire black and red.

The 'little block' is in the old ford Sierra loom all chucked in the back of the ambulance but I can find it in the morning.

The premier loom doesn't have any of these technical bits and its a motorcraft distributor with a normal points/condenser set up. I have 8 coils in various conditions, none tested. Two are definitely for a ballast system, the rest I have no idea but will check for part numbers in the morning.

I assume, as I don't have a diagram in front of me, that the sender for the tacho goes on the same side as the wire to the points, which is green, as that will be the one affected by the pulsing of the coil. 

Its fireup time tomorrow, wish me luck.

[Dave Adams]

the coil gets very hot and the points will burn out very very quickly.........not recommended.

[Big Vern]

You have a premier loom. when I got mine he said I'd have to use whatever ballast system was with the car - it goes between the ign switch and coil pos, then theres another plain wire from the starter main terminal where the power goes into the motor itself. This is so you get 12v to the coil on cranking as in reality cranking drops your battery volts to about 9V anyway. Once the ebgine is running then it reverts to 8v at the coil via the ballast resistor. TBH I'd buy a non ballast high energy coil then you don't have to worry about the ballast resistor.

Would be interested in borrowing the wiring info that came with your loom as mine doesn't match the loom I have and I've no idea which fuse in meant to be which?

Do the club still get a discount from premier?

[Dave Adams]

make your own Vern ....very easy, quick and cheap.
