Disconnect the alternator 4-pin connector. Turn ignition key on; engine not running. Voltage test pin 3 of the connector. It is a white/red wire according to my '95 service manual. You should get battery voltage. If you have no voltage; check for open wiring from fuse to bulb to alternator. Check for a blown bulb in the charge warning lamp gauge.
If you have battery voltage, check for a faulty alternator ground wire.
Normally you can bypass the charge warning circuit by simply revving the engine up above 2500rpm. This will be sufficient to energize the alternator field coil and the alternator should continue to charge until the engine is shut down.

ok update been busy so not much progress. With ignition key ON I am getting 12.10v at the alt output, 12.10v at the first pin on the plug, the other (white/red) is getting voltage too but its 11.95v, when I turn the ignition off the 11.95v goes to 0 while the other 2 stay at constant resting battery voltage around 12.4-5ish, seems normal right? also checked fuses again this time checking their continuity to make sure I wasn't missing a blown one but nothing all good. Charge light lamp does not illuminate when I start the car or ever period, thats my only good lead at this point that charge light lamp, I've tried other known working bulbs but ill buy some news ones to eliminate the possibility of blown bulb... any other ideas? Thinking off adding an extra ground just to cancel grounding an issue but idk
