Ever wonder what's inside the Volage Regulator ?

 

I looked ...so I guess I wondered what was inside. No surprise what it looks like ...and I don't think I'll troubleshoot any resistors or diodes but thanks for posting - Inquiring minds need to know these things .......

 

That particular example looks a little toasty.

 

Way more than I thought would be in there. I guess it would be better to buy than try and make.

 

thanks for the foto, i always wondered

 

I know I'll sleep better tonite seeing the innards of a voltage regulator. Can't wait to see the insides of an inner tube.

 

 

I bet it smells good

 

Must be some platinum and gold in there to justify the dealership price of those things.

 

This VR came off a wrecked bike. It still worked but the case was cracked. The components that look burnt still have a little of the rubber material they pour over the unit on them.

I worked with rectifiers for years providing Cathodic Protection to Pipelines and Facilities. I always wondered why there wasn’t a simple way to trouble shoot a VR thinking it was a simple 3 phase system with a voltage limiter.






I searched for a schematic but never could find one. The ohm and diode check readings I got with my meter didn’t jive with what I thought I should see so I dug the rubber away and found the circuit boards.
No wonder the Manual is so basic for trouble shooting the VR : If the output is below 13 V or above 15.5 V and the stator output is normal and the + and - cables from the VR to battery are good, replace the VR.

Just got curious
