SOURCE: Where is the voltage regulator on a 99 mercury

1999 ford cougar alternator putting out reduced voltage at 4000 rpm and over. Under 4000rpm fine. Voltage up to 4000 rpm about 14.5 volts. Over 4000 rpm it starts to drop and can go as low as 11.5 volts. Any ideas.

I have a1979 Mercury Cougar RX7 and can't find replacement voltage regulator.It has a factory amp gauge so it doesn't take the regulator listed at the parts places.Do I need to rewire it ?

check with an auto electrician as the voltage regulator may be an integral part of the alternator and not separate
all depends on the alternator as to if you have a outside regulator or not

Where is the voltage regulator on a 99 mercury cougar?

The voltage regulator is a part of the alternator.If you are having pulsating issues then look for grounding issues like a corrided eyelet or loose grounding bolts.

Cougar 1999 lights flicker after changing alternator have 14.7 volts on output

Voltage regulator is not doing its job, and it is allowing excessive voltage into the circuit. If you do not address this problem, some light bulbs and LEDs might start to burn out. Either replace the voltage regulator, or modify the circuit between alternator and regulator to match later model cougars, where this problem was solved.
