Metro Turbo Ignition Coil
Turbo Mini Forums

Does anyone know what the resistance of ignition coil on the metro turbo is?

I need to get a new one for my engine build and have been told it was 0.7-0.8 ohms, but want to check if this is correct?

Is the Metro ignition feed ballasted or non?

I think it was 12V, 0.7ohms and non ballasted, but i'm not 100% sure.

Would be great if anyone out there thats had to get a coil could shed some light on the subject!

If there's an 12v supply to the coil its non ballasted.
Its been too many years since I messed round with a coil but I seem to remember the dark blue Haynes manual (if you have access to one) for the mini listed the resistance values for the coils, Im not at home currently to double check.

The coil for the electronic ignition is indeed having a resistance less than 1 Ohm. To know if your needs a 12V (non ballasted) or 9V (ballasted) type of coil could be sorted out by checking the wiring loom. If there is a wire from the startermotor coil to the + side of the ignition coil, then it is ballasted. The regular wire to the coil then has a certain resistance or a resistor block is in the circuit, having the 9V coil to work, and getting full 12V power suring starting.

All metro turbos were unballasted as they were electronic ignition right from the start.
