I have just bought a mini that was in need of some engine parts..the ignition coil was one of them and now i have it i do not know which wire goes where ( as i did not remove the old one )

Can anyone help either with a picture or good description?

Much appreciated

what year is the mini.

Sorry its a 1985..mini ritz

ok unless its been messed with its a ballasted ignition system so you need a ballasted coil


Look for a white/yellow wire this goes to the positive on the coil you should also have a white/pink wire this also goes to the positive on the coil. You may find that both these wires share a spade connection anyway and are joined.

There should also be a white/black wire this goes to the negative on the coil. down near the dizzy should also be a white/black which joins onto the wire coming out of the dizzy.

Thank you
I will have a look tomorrow and let you know how it goes

Is there only supposed to be 3 connections on the coil? I know for sure the one i have has 4 connections?

For info, look at bottom right side of page 12.36 on the link below. This shows 4 connections, the 3 identified above plus a second White/Black which feeds the tacho. This suggests that you have the multiple instrument pack not the single one shown on the previous page.

I have a white/black double connection and a white/yellow single connection and then a single white/black connection...i dont know if i have the right coil or am missing wiring?

[lrostoke]

If you have the white/yellow then you should have the white/pink .

1985 will be ballasted as standard but a lot do get converted. So it may be taped back into the loom or even cut off.

Sorry guys, I must have been having a senile moment. Here is the link:

If you measure the resistance (with meter) across the + & - terminals (with cables disconnected), you should get the following results:

Non-balasted coil 3.0-3.4 Ohms
Balasted coil 1.2-1.5 Ohms

The following is an extract from the Haynes manual:


Primary resistance at 20ºC:
Lucas LA12 and 15C6 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.2 to 3.4 ohms
Lucas HA12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.0 to 3.4 ohms
AC Delco 9977230 or Ducellier 520035A . . . . . . . . . . . . . . . . . . . . . . 1.2 to 1.5 ohms
GCL 144 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.3 to 1.5 ohms

Ballast resistance:

Hope this helps.
