Morris Minor Owners Club

I’m about to install an alternator and need to change from positive earth to negative earth. I am trying to find information on this change.

Loads of threads on this. Some variations may depend on the particular version you are working on?

For example, see viewtopic.php?p=653272&hilit=convert+ne ... th#p653272

Most components on the Minor will work happily with either +ve or -ve earth without any change; but do make sure that the coil low tension wires are correct for +ve or IGN and -ve or CB.
