<DIV><FONT size=2>If you have a rev counter i.e. mechanical there will be a
thick flexible cable like a speedo cable going to the engine. MGBs got the
electronic tach in 1964, for what that's worth.</FONT></DIV>

<DIV><FONT size=2>Other than that it depends if you have any other electronic
stuff like ignition (probably unlikely) or radio. Radios in a car not
touched for that long could well have a polarity reversing plug.</FONT></DIV>

<DIV><FONT size=2>The heater fan may reverse and work less well, but if both
wires going into the motor are the same colour with no identification stripe on
one of them then probably not.</FONT></DIV>

regulator, are there any concerns with changing my 65 Spridget to negative
ground?
<DIV dir=auto>Is tach mechanical or
