Question about 1991 Toyota Celica
Get a multimeter and hold it on the battery contacts. With the power off, it should read around 11V. With the engine running, it should read around 13.5V.
If the power off voltage is under 11V, you need a new battery.
If the power on voltate is under 13V, you need an alternator.
Is the clicking noise at a constant rate, or is it related to the speed of the engine? In the latter case, it's probably a physical defect in the alternator. If it's more constant, it may be a wiring issue - there could be an arcing problem. That could be a problem within the alternator, or somewhere between the alternator and battery.
Before you mess with the alternator, UNPLUG the battery - it's very easy to short the main battery contact with the alternator housing, which is connected to ground/negative.
