1980 ea71 GL-5 - Voltage Regulator?

[Ether Circus]

Hi! I found a good deal on a 1984 hatchback, and the owner says it just needs the voltage regulator. I believe that most of these are built in to the alternator. My question is, whether or not it is the same on my 1980 ea71 motor. If so, I will go get this car today, swap out the alternator, and drive it home. Any info would be great. Thanks guys!

The 1980 I had was an external regulator, i believe one of the last years they used an external. I find rockauto.com an excellent resource for looking up part numbers to check compatibility-give that a shot. In any case it is prolly something that can be fixed fairly easily, check VR, alt , witing etc.

 

let us know if you score the car!

An '84 should be internally regulated (built into the regulator). I can't tell from your post if your are planning on swapping out the alt from your '80 ea71 onto the '84 or just using it for comparison. If the '84 is an ea81 and you mean to swap from the ea71 I couldn't advise you on fitment, but stock reman's for the ea81' are pretty inexpensive. Snag the hatch! You'll be glad you did.

You will be better just to buy an alternator for the EA81 found in the 84 hatch.

Yeah I was wanting to swap out the alternator from my ea71 into it, since the ea71 has a bad rod knock. But if that won't work, then that won't work. I still might get it though... if he still has it tomorrow morning, i'll be there to get it. Thanks for the help guys!
