It is inside the alternator which will have to removed and dismantled for replacement
The voltage regulator is built into the alternator.
How do remove and replace the ignition switch of a 1983 Oldsmobile Regency?
The voltage regulator is located on the firewall, just right of center of the engine.
It's internal. Inside the alternator.
I'm guessing voltage regulator? The voltage regulator has a plug on it so when you replace it all you need to do is unplug the old & plug in the new. Don't forget the ground wire as the regulater requires a ground to the mounting bolt to work. If the plug is gone you will need to get a wiring diagram. You may be able to get this at some parts suppliers who have Mitchell, Shopkey or Alldata available for their customers.
I can only tell you that the Voltage regulator on my 2009 CT110 is on the right hand side behind the battery cover. It's a small finned aluminium box with a black multi plug underneath. You'll see it in the top right area next to the fuse.
The Chevrolet voltage regulator has been built into the alternator since 1973. I HAVE A 86 BLAZER AND MINE IS BUILT IN THE ALTERNATOR. YOURS MIGHT BE ALSO. IT ALSO COULD BE ON THE FENDER WALL ON THE LEFT SIDE OF THE ENGINE COMPARTMENT.
