Kerbsidemotors early Mini alternator fitting guide

Converting from negative to positive earth and fitting an alternator.


The following procedure is the way to carry out this conversion on a Mini. The procedure will be pretty much the same for all late 1960s and early 1970s British cars (I.E. Ford, MG, Morris Austin, Rootes)


Fitting an alternator will make the car more reliable as the AC current from the alternator is more stable than the DC from a dynamo. This conversion also makes the sometimes unreliable control box redundant.


Converting the car to negative earth will allow you to connect modern stereos, electronic ignition, modern fuel pumps etc. Also because of the way the electrons flow the car will not rust as fast!


Another point to consider is while fitting an alternator increases the reliability it removes some of the originality. This could affect the price of the car.


What you need:


An alternator. Lucas 16ACR (Or similar recon) is probably the most suitable. 18ACR and 20ACR will fit too but because they generate higher current they may cook the wiring!


Alternator terminals. Supplied with genuine new Lucas alternators (
