'87 Cougar -- too much charge

November 17, 2005, 10:49:07 PM

Car has too much charge. Guage is up to the top and it's beeping. Charge goes up when on the gas. Charge goes down when you put it in gear and hold the brake. Lights dim as the charge goes down.

Could this be the regulator or alt? Is the regulator built into the alt of on Cougars?

Nope there is a shiny metal box on the passenger side of the engine bay. That is the regulator.

If it is the 5.0 you have an internal regulator, sounds like that is bad.

Sorry guys, I forgot to mention, it's an EFI 302. Looks like I'll be pulling the alt tomorrow. Thanks.

How does that tension pulley come loose? Is that the one where it will spin around if the belt comes off?

Put a wrench on the tensioner pulley bolt and pull it upward until you can slip the belt off. Once the belt is off slowly release tension on the wrench until the tensioner comes to rest.

Thanks for the help, guys. New alt w/ regulator is in. Got her together and going. Sure is a fun car to drive.
