Whenever a starter motor in any vehicle clicks it is telling you that it is not getting enough current.At this point I would probably replace the cables and make sure that the ground cable is attached to clean metal and grounded to the engine and a secondary cable is grounded from engine to the frame. Over time these connections corrode ,sometimes from the inside out. A starter motor generates around 20hp so they require a lot of current and will refuse to start when cables are not up to the job.
Chances are the starter solenoid has developed a bad spot. If you are handy you could try to replace just the solenoid otherwise it may be time for the starter/solenoid combo.I assume you have checked your battery cables.

Repair the alternator to battery connections or replace the battery.
Disconnect the 1990 Regal battery. Remove the alternator belt. Unhook the wiring from the alternator then unbolt it. Remove and replace the alternator then reconnect the wiring, belt, and reconnect the battery to finish the installation.
It sounds like you simply need to change the alternator. Easy test: if vehicle will start, carefully remove the ground/negative cable from the battery (may help to llosen slightly beforehand). If vehicle runs, turn on lights; if it still runs, the alternator is fine. All vehicles should run on alternator only. If the vehicle sputters and dies, the alternator is dead. Replace alternator, and VERY IMPORTANT, fully charge battery before engaging alternator. A weak battery can damage a new alternator causing alternator death.
It's not at all uncommon. A failing alternator can easily damage a battery.
follow the positive battery cable to the starter solenoid. there's three wires and two 8mm bolts. disconnect the negative battery cable then replace the solenoid by transferring the wires from the old to the new
The starter solenoid is attached to the starter. Follow the positive battery cable from the battery, it will lead you to the starter solenoid. The starter would have to be removed to replace the starter solenoid.
Check fuses first. If fuses are good, check the voltage from the negative battery cable to where the wire bolts onto the back of the alternator. (With the engine running). If you can't reach the back of the alternator, then measure across the posts of the battery. Voltage should be about 14 volts DC. If lower than that, replace the alternator. When you replace an alternator, it's a good idea to replace the battery, as a precaution.
Simple, just replace your alternator..
Disconnect the 1988 Century battery. Remove the alternator battery. Disconnect the alternator wiring, then unbolt the alternator. Bolt in the new alternator, then reverse the procedure to finish the installation.
