>Over the weekend the local car club had a garage tour of various projects
of
members, lots of fun. At one stop the owner of a Healey was saying the
regulator that was shared in the TR2&3's, Healey's and others had a funny
dangerous quirk. If you pull the fuses from the fuse block you can
actually
run the car, with full lights etc. The down side is the huge possibility
of
a wiring harness fire. It seems the regulator can feed back into the
circuit, bypassing the fuses, and over feed the harness.
Has anybody heard of this? I would assume some part of this true due to
the
inline fuse that is added for additional rear circuit protection. Any
clarifications available? Is there anything to worry about? Any other
precautions?

Yes you can pull the fuses from the fuse block and run the engine and the
lights. Why? Because they are not fused. The Healey, like the TR4, has a
fuse for the green wire and the purple wire. Only those items that run off
of those wires will be disabled by removing the fuses. Also, the regulator
has nothing to do with it. About the only melt-down that can be caused by
the regulator would be if the cutout contacts failed to close at which
point the battery would feed much current into the generator armature and
the brown wire will quickly overheat.
