Ok, it should be connected to the "unfused " spade connector
Take your test light and make sure that you have power to that pin with the key on and then make sure that you have power at the other end of the wire going to the distributor.
The wire needs to be connected to the BAT connector on the distributor and not the tach pin in the middle. Make sure that both female connectors are tight on the pins as I have had trouble with mine coming loose due to less than steller wire connectors I think.
You might also check to make sure that the carbon and spring are in the cap. You do have the connector from the distributor to the cap connected? No need to know why I asked that one.
