Answer

Alternator or voltage regulator going bad. Not keeping a costant voltage/amp, it fluctuates.



ALTENATORS ARE THREE-PHASE UNITS, THESE PRODUCE A SUPPLY OF VOLT/CURRENT IN A/C FORM. THE CIRCUIT(S) ARE NEITHER POS OR NEG BUT RATHER DEPENDING ON THE PHASE DECIDES WHETHER POS OR NEG WILL FLOW... THE REGULATOR SHORTS TO GROUND ANY AMOUNT OF VOLT/CURRENT OVER ITS MAXIMUM AND A BUILT-IN RECTIFIER CONTROLS HOW THE CURRENT FLOWS AND IN WHAT PREDETERMINED DIRECTION IT IS ALLOWED TO FLOW HENCE POS/NEG...

YOUR ISSUE IS THE ALTERNATOR AFTER YEARS OF SERVICE HAS LOST ITS ABILITY TO PRODUCE VOLT/CURRENT THROUGH ONE OF THREE PHASES....

REMEDY:REBUILD OR REPLACE THE ALTERNATOR...

In a 1997 Lincoln Continental : To the right of your headlight switch in the dash is a ( panel dim ) switch I believe if that is turned all the way up then the interior lights will come on

Should be in the main fuse block. Look for a fuse labeled "courtesy".
