You need to check all the wires in the charging system and starting
system to make sure the wires and connections are still in good shape. It
almost seems like that cut wire is going right to ground.
You need to trace that cut wire to find out where it goes and see if it is
shorted in the harness somehow.
The NY wire should run from the voltage regulator D terminal to the bulb and
the W wire should run from the bulb to the #2 ignition switch lug.
I had a lot of difficulty with voltage regulators. The points would get
dirty or arch together so take the cover off the VR and check the points. I
installed a voltmeter to catch VR problems sooner. I converted to an
alternator once I figured out the complete system and how to clean up the
wiring at the VR.
Slow cranking can be due to a low battery, bad connections at the starter
relay or battery or the relay going bad.
Good luck
Hope it is something simple with little damage.

The other day, I decided to finally get around to fixing my non-working
ignition warning light. It's been in that condition for the 23 years I've
owned this Tiger. During that time, I've had flawless performance from my
generator. Even had a battery last 18 years in this car with only
occasional driving!
The bulb tested fine.tracing the wiring, I found it was cut clean about 3
inches behind the light. I found the other ends hanging in the wiring. The
wires were color code correct with the wiring diagram. This is probably
when a bell should have gone off, but I went ahead and connected the wires
and turned on the ignition. Turning the key on produced a red light.
Started the car, still had a red light. Revved the motor, still had a red
light (although somewhat dimmer). Darn thing never went out! After about a
minute or so, I shut off the car and disconnected the wires.
Upon re-starting the car, the ammeter showed a slight discharge. Revving
the motor never budged the ammeter needle. Previous to connecting the
ignition light, the ammeter would swing from slight discharge at idle to a
positive charge condition while running at speeds above idle (as it should).
I was hoping the ammeter had just taken a hit from the ignition light hook
up , but shortly thereafter I developed a miss in the engine and cranking
speed at start up was starting to slow. Apparently, the generator didn't
take too kindly to the ignition light experiment. Now I know why the wires
had been cut and left hanging there!
I'm hoping those on the list with more electrical expertise than myself (and
that would be most of you) might be able to shed some light on what
happened, and if you think the generator is a goner.TIA!
