Morris Minor Owners Club

Hi, want to replace old 1964 key switch two pin with new style plus new solenoid switch , car is fitted with alternator so negative earth .Do I have to fit another wire to do so ,think white with red tracer ,been told it should be resistor wire is that correct?

You will need the extra wire from the switch to the solenoid, just white/red 28/0.30 25 amp should be ideal. No idea what "resistor wire" is - all wire has resistance.

Yes -you will need a new wire from the new switch to the solenoid..... Negative earth has no effect on any of this - and CERTAINLY NOT a resistor wire ! Where do you hear such nonsense????

Hi thanks for info , been told resistor wire needed because there was no voltage stabilizer in that circuit ,you say its not nessacary thanks

What has a voltage sabilizer got to do with it.......? This is amazing... Who ever is telling you these stories.......steer a wide berth in future!
Later Minis (and some other Leyland cars - but never the Minor) ran a 'ballast' ignition circuit, where indeed a special white/yellow (usually...) resistor wire is used to feed the coil with ~ 9 volts during normal running. It is a low impedance coil, designed to run on 9 volts... . During starting, the resistor wire is by-passed, to feed full battery volts (which will have dropped to maybe 9 or 10 volts due to the starter current draw) straight to the coil. So there is a better spark and faster starting. This may be where some of the confusion comes from.... The 'voltage stabiizer' is mounted on the back of the black faced speedo and supplies a simulated reduced voltage to the fuel gauge, which is a 'hot wire' instrument. Nothing to do with Ignition switches..... If your car doesn't have a black speedo, it won't have (or need) a stabilizer.

Hi thanks for info the friend is a Metro man and probably confused .Will follow your advice thanks

Any 'Metro' owner is bound to be confused......take pity on him.....
