Voltage regulator

[acepatt]

Looking for a suggestion on a universal regulator/rectifier to work with a stock generator. The ones I found on line have bad reviews or dont seem work with stock systems.

This is an oem Yamaha. Expensive, but you know it will last 35 yrs.

Or build your own.

How do I build my own.

Thanks the vr115 is easy to get but do I still need a rectifier ?

 

[5twins]

Yes, these charging systems require both a regulator and a rectifier. But, the VR115 may not be the regulator you need. It depends on the year of your charging system. 650s up to '79 can use the VR115. In 1980, the way the brushes were wired was changed and a different regulator is required. The rectifier needed is the same for all models.

It is a 75. I will just source a rectifier on line to add. Thank you all for the info.

acepatt.....................tell us what year is your bike, or actually what year is the engine and alternator.

OK, I see you replied with 1975.
Have a read of this link:

NOS VR-115 and a new 3 phase rectifier should be under $30.00

VRREM7-XS for Yamaha 650 twins that originally came with a separate
regulator and rectifier

This unit requires a plugs into the original regulator and rectifier connectors on the wiring
harness but requires custom mounting. The leads are 10" long giving you plenty of options as to
where to mount it.

$145.00

Come on 5twins, RG, why haven't you picked up on the OEM Boats.net statement that a Combined Reg/Rect will work on models that don't have the combined Reg/Rect.

Very quick to point this out in other threads and dissing Mikes and Chinese parts sellers for making false statements

Unfortunately, I missed the year of his bike. I assumed he had a combined unit as he stated reg/reg and he also posted on the Facebook page with "electronic ignition".

 

[acepatt]

I appreciate all the information from everyone. Thank. You. But please keep the thread informational.

Not you fault littlebill31 its the Yamaha parts Suppliers who cross reference part no's for sales purposes.....................These guys are supposed to be the experts.............if they are getting it wrong then how can a novice be expected to get the right part right.......................... For those guys who do know what they are talking about, they should be dissing these Yamaha part suppliers for giving the wrong information..............But they don't, they actually use these, and suggest these guys for references....................I have been all over this problem every time i have sen these guys linked to..................
