remember that TigersUnited.com is not dead, and among other resources it has a
complete scan of the Tiger Workshop Manual, including good re-digitized
drawings of the wiring diagram.

So, with respect to that drawing:
- Your tach should be powered through the spade connector on the back of the
tach. That should be connected to a green wire that is energized only when the
ignition is on or in the start position.
- Your tach should be grounded through the black daisy-chain wires that need to
be connected to the dash frame somewhere (not just gauge to gauge to gauge).
- The OEM wiring has the coil power run through a white wire, looped through
the transformer U-shaped metal piece and plastic frame that is mounted on the
back of the tach. It kind of sounds like the Nissonger rebuild gave you an
alternate means of sensing the ignition with their white "signal in" line. You
should have got a wiring diagram with the tach, if they changed the way it can
be wired up.
- That OEM white wire needs to connect to one end of the ballast resistor as
shown in the wiring diagram (and the other end plugs into the ignition switch,
not the tach). It supplies power to the coil through the ballast resistor when
the car is running.
- The white/blue wire runs from the solenoid to the ballast resistor to the
coil positive.
It sounds like you need to make sure that the white wire you plugged into the
tach, is connected to the ballast resistor at the other end. If so, unplug the
tach end, loop it through the transformer block, and plug it into the #2
terminal on the ignition switch.
If the tach works properly, then you're good. If it does not, then try looping
the white wire through the transformer block in the opposite direction. If that
still fails (but the engine runs properly), then abandon the transformer and
use Nissonger's signal wire. As Gary says, that wire should be connected using
a new extension wire to the coil negative terminal ( where the points connect
).
Good luck,
Theo

The Signal wire should probably wire to
the points or low side of the coil.
The white wire should not end at the tach
but would do a one loop through the coil
pickup on the back of the stock tach and
then run to the ballast.
You do need 12v to the back of the tach
spade terminal and a ground.

Thanks to Donald Antilla and Ron Fraser for their quick replies. They have me
on the right track now. In my new wiring harness I have one white wire that
comes out of the harness behind the tach and I assumed it plugged into the
white wire (labeled "signal in") on the back of the tach. My tach was rebuilt
by Nisonger and has the updated electronics. I ohmed that wire out and it is
the one that goes to the ballast resistor. So should I run a new wire from the
ignition switch to the tach and piggyback the ballast wire to that?
Thanks,
Joe Brown

The starter solenoid temporarily supplies 12 volts to the. Oil while the
starter is cranking.
As soon as you release the key that temporary 12 volts is disconnected and the
power to the coil is via the ballast resistor.
It sounds like you either have a bad ballast resistor or broken wiring to the
ballast resistor.
Temporarily add an alligator jumper across the two tabs on the resistor and see
if it starts. If it does start you have a bad resistor.
And if that does not work, start looking for lack of 12 volts INTO. The ballast
resistor.
