Reg/Rec Replacement

Trying to clean up the battery box and want to switch to a more reliable Regulator Rectifier.

I read 5Twins recommends the AC Delco VR115 for pre 1980 bikes. Does this replace the rectifier also or do I need to buy a separate rectifier?

Most likely need a Rectifier
If a googling
https://www.amazon.com/Standard-Motor-Products-VR115-Regulator/dp/B000C8053C

Only has 4 pins ..

Stock rectifier 5 pins

Regulator should go but the Rectifier can be Usable

Yes, you will need a rectifier as well (or continue to use your original). Many of us use this one from Windy Nation .....

Thank you sir.

Thank you sir.

I built one with the Fiat regulator. I just cut the wires and connector intact and spliced them on the new regulator rectifier.

working on a '78 XS650E, the rectifier under the battery box is toast - are you saying the one in your link could replace the original one ? - trying to keep all as original as possible thus not really looking to change the system, but obviously the original are not around any longer and i hesitate to buy a used one on eBay.

Yes, it replaces the original perfectly. But, you'll need to build a little bracket for it that can act as a heat sink too. Many just mount it on aluminum plate. I probably went a little overboard, I used an section of heat sink from an old computer .....

So perfect and a lot cheaper than many of the other options. Thanks for sharing
