Battery supplies voltage to the engine fuse box so make sure these fuses are powered properly. If the BTN fuse was powered then the horn or flashers would work. If the Head fuse was powered properly the headlights would turn on. If the Main fuse was powered then the turn signals would work w/key to on. Do any of these items work?
And is the car an S4 or S5?

Check your Meter fuse and see if the warning lights have power. W/the alarm not being powered that's going to prevent the car from being started unless you either address the alarm issue or bypass it. To temporarily bypass it you can bridge/jumper two wires together that are found in the Starter Cut Relay plug which has but four wires. There are two Black/Green wires in the plug and one is of a thicker gauge than the other B/G wire. Jumper the thicker B/G wire to the Black/Blue wire in the same plug and try to turn the car over. W/key to start the Black/Blue wire must have voltage. Does yours?

Well... have power to warning light signals only but not the warning light cluster and the alarms working.. just leaves the starter, seat belts and warning light cluster... could this be a bad ignition switch?

There are three plugs that are relevant at the Ignition Switch. Looking from the Front harness side of things there will be a B/R wire by itself. A Blue wire and a B/R wire in a second plug and a B/W wire and a solid Black wire in the third plug.
You say the "alarm's working.....just leaves the starter." I have not a clue as to what this is supposed to mean.
"have power to warning light signals only but not the warning light cluster" Besides the warning light cluster, where else are there warning light signals.
W/key to start the Black/Blue wire at the Starter Cut Relay must have voltage. If it doesn't your car is going nowhere. Does this wire have or not have voltage w/key to start?????????????????????

sorry meant to say the alarm is working but the starter still has no power and the clock on the cluster is working but the warning lights are not. the turn signals only work when the emergency flashers are on but they dont work otherwise.
ill recheck the voltage when i get back home from work, my meter took a crap have to buy another one
thanks man

Have you checked the Meter fuse? If it was good then the gauges would work. Do you know if the B/Y wire which powers the idiot lights has voltage w/key to on. At the CPU the largest plug houses the B/Y wire. W/key to on does it have power? In the same plug is a Yellow/Blue wire, which when grounded it should cause the idiot lights to turn on w/key to on assuming the B/Y wire has voltage w/key to on. Does it? Either the B/Y doesn't have voltage or the warning light relay in the CPU is bad or there is a connection problem at the back of the idiot light unit.
And when you grounded the wire off of the back of the alternator was the key turned to the on position as it should have been?

Just realized the harness used in this car is a n/ a harness from a 90 convertable.. when i bought this car wasnt running, so i pulled the motor rebuilt it cleaned everything up. Dont know the diff in the t2 and n/ a harnesses, but checked the b/y wire on cpu and it has no power

And you checked the voltage on the B/Y wire w/key to on? And did you ever check the Meter fuse?
And the Black wire in the large CPU plug is a ground wire and can be used as the ground source for the multimeter when measuring for voltage on the B/Y wire.

Would a badly installed boost controller to the ignition cause these problems?.... after pulling the cover theres about 3 seperate relays wired in somehow.. rigged in otherwords
