Hi check the output on your alterantor at the battery terminals. Probably putting out to much voltage. Make shure the car is running when you test it all you need is a volt meter. Andrew

x2 on the alternator

 

[AREA 91]

Time for a new voltage regulator.

x2 on the voltage regulator.

Can be bought new for less than $50, and is 4 T-20 torx screws to remove/replace. It takes all of two minutes to change when you have the alternator out.

get rid of the radar detector too, go race on a track if you want to speed.

X3 on the voltage regulator and double chech the wire going to the battery my 91 did the same thing and the wire that goes to the positive terminal was arking and causing the problem

Keep the radar detector.

 

[Grantorinslo]

Replace it with a valentine1...

 

[nothingtoseehere]

+1 Having a radar detector does not mean one is street racing

 

[Storm-Chaser]

Yes. Electrical stuff can have intermittent failures. It may also be the brushes, which are screwed-to the back of the voltage regulator. Replacing the voltage regulator replaces the brushes.

ok i got the new alternator today but i took a look unter the hood and this aint gonna be easy to fix so can anyone give me a website with the steps for installation and removal

 

[93rev2sev]

Simple to follow 93MTX alt directions.

Remove battery:
-disconnect cables (negative first)
-back off hold down nuts
-swing hold down out of the way
-lift battery out, set aside

Disconnect Alternator:
-Pull out plug
-Remove power lead (usually a 10 or 11 mm socket)

Detatch alternator:
-Remove the (probably 15mm) bolt from the bottom, rear.
-Remove the (probably 13mm) bolt from the upper
-Loosen and remove (if it'll clear the battery tray) the long through bolt at the bottom, front
-Wiggle alternator from vehicle.


It's actually very easy to replace.

 

[Joe_SHO]

before you install the new alternator, you should try simply cleaning the battery terminals.
