Hey everyone, so I’ve seen a couple threads on alternators on here, but I’m just not sure. I’ve got a 1980, 245 and the alternator was just determined to be bad, not surprising as when I bought the car, the previous owner had it wired wrong, like I’ve seen on so many others. Anyway, it’s finally going bad, and I’m not sure which alternator I should settle on, amp wise. One person said either the 50, 70 or 80 amp alternators will work, but why is there such a difference? I’m definitely going to try and find a Bosch, but should I go for 70 or 80 amps?
Are there many options just for different amounts of power usage per car?

 

A 70 amp alternator will work just fine.


(unless you have 3 amps in the trunk and a double subwoofer!)

 

Thank you hoonk, with that, I just ordered one that luckily wasn’t special order. Hopefully I’ll be on the road again real soon.

 

don't throw out the old one just yet... find out what was really wrong with it..and 'just determined' isn't an answer...

 

i used the Bosch of Rock Auto. You will notice a difference in your headlights and power windows 👍
