Brian,
The messages, below, are interesting.
My P-type manual is 2000 klms away with my son & the car. I do have J3/4, L,
K3 & N Manual here. Sure wish I had an R-type manual.
How do I tell from the wiring diagram, if it is negative or positive earth.
>From memory, the P-type wiring diagram does not show what colour cable was
used from battery to front of car.
Anyhow, it is an interesting subject
Thanks

If you check the wiring diagrams for the MMM cars you will see that they were
negative ground from the begaining.
