What Coil Do I Have?
Posted 24 March 2019 - 07:21 PM
I thought ballast is 1.5 and non ballast is 3 ohm. But mine is 2 with all wires disconnected.
I just want to make sure I replace it with the correct type.
Thanks for any help.

There is no apparent improvement with a 9 volt coil and very few Minis have them.
By the way, to repair the front loom takes about 6 hours when it burns out plus the cost of the necessary colour coded cable, connectors and loom tape.

Is non ballast better, if so why? As I thought the advantage of ballast was better starting.
No, all it does is give 9 volts once the engine is running. During cranking the coil is fed a full 12 volts

As already said by Cooperman and Cal the way forward is to get rid of the 9v system and convert to a 12v system with a standard 12v 3ohmn coil with your planned upgrade to a electronic trigger I assume in your current distributor. Guide if you need it in the FAQs electrical section on fitting a Electronic Trigger.
The last one I had the misfortune to sort out when the ballast built in the loom burnt up took over 4hrs to sort out x labour costs you do the maths.
If you disconnect the white/pink at the fuse box connection, either cut it off/tape back you kill the ignition on power to the ballast wire and then no need to remove it from the loom, cut or tape off at the coil end your safe. just run a new ignition switched feed to your new 12v coil and your sorted.
