i need help soon.. electrical problem

Promark,
Everybody here loves to help, but you need to reply to their questions or they will soon lose interest.
Does your voltage regulator look like the one posted?
Does your alternator look like the one posted (square back) or is it the earlier round-back type?
Do you have a multimeter? It is an essential tool. $3 at Harbor Freight.
We can't assume anything based on the year of your car since many electrical systems have been upgraded, ex. your electronic ignition.
I think over-charging is the likliest fault.
Have you checked the bulbs in the failed lights. Is the filament gone? Do you measure a resistance?
