Jack,

Check out this link:  https://www.mgexp.com/article/lucas-colours.html.

It shows the white with brown tracer as oil pressure gauge and white 
with black tracer as ignition coil contact breaker to distributor 
contact breaker, or distributor side of coil to voltage impulse 
tachometer.  I  would want to check both of those wires and see where 
they really go.  Does your car have a tachometer that should be using 
that wire?  Is the tachometer working?  I don't know how the oil 
pressure gauge would respond to the tachometer input.  It would be 
scary to think that you weren't really reading oil pressure before 
and the gauge was just responding to the tach signal that says the 
engine is turning, I don't really know if any of this is 
plausible.  I am doing a lot of guessing and speculating.  I would go 
back to what I said before, check where those wires really go.

-Steve T.

The electric oil gauge _would_ respond to tach pulses, but in a 
significantly different way to how it should respond.  But then the tach 
wouldn't work - and that wouldn't respond to an oil pressure sender.  It 
doesn't even begin to explain how - apparently - both oil gauge and tach 
were working normally before the alt change, and both apparently are now, 
having swapped over an apparently previously used white/back with an 
apparently previously unused white/brown.

Jack, You just answered you own question. If you have installed a electroni=

Correct, and there should still be another white/black from the coil -ve =

White/brown, white/black, not that much difference as far as getting =
