the alt wont work the loght on the dash unless there is power to the ignition wire on the alt to turn it on.

With a multimeter you should have 12v on all the wires that go to the alt with the key on,

with a test light one should glow dim and the others all should be bright.

yeah if its only 9v then the alt obviously isnt charging. is it a 16v 4age? if so, you need to wire up the 3 wires on the back plug + there should a terminal on the side of the alternator which needs to have a batt source wired up for it to charge.

can get more descriptive if you want

what do i wire up the three wires to? is one of them a wire for dash light?
and then just + from bat so side of altenator?
