Put a multimeter on dc. Place the probes on the battery terminals. You should see between 13.2 and 14.8 volts with the engine running. Do this at idle and while you rev the engine too be sure the voltage regulator is not under or over charging the battery

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

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.

Alternator will not charge ,has new alt

If your car is equipped with one, have the external voltage regulator, or regulator module checked, usually mounted on the inner fender well on passenger side.
Even with a new alternator, if the regulator is bad, it will not charge.

Flickering lights

In some 1999/2000 Cougars the wire between the battery and the voltage regulator(altenator) had a resistance reading that is too high. Ford has issued an TSB 00-25-6 that has instructions on how to replace this wire. The part # for the replacement wire is
1S8Z-14A411-AA. I'm in Michigan and a local dealer found one for me in South Bend,IN

My 1999 cougar cuts out while im driving

if it is a short, you can lift the carpets in the trunk, or remove the front bucket seats and lift the carpets in the interior. it may also be a bad voltage regulator in your alternator, in which case you will need a new alternator. you can test your voltage with a voltometer, and see if your alternator is producing more than say 15 volts while running.
