Broken Voltage Rectifier.. I think?
Hi all, I'm new here.
To start off, a little about myself: I live in Ireland and I bought a 1995 BMW F650 Funduro about a week ago, love riding it so far!
Today I fitted Oxford heated grips and took the bike out for a test ride in the cold. I noticed the grips weren't getting warm and when I glanced at the controller, I saw the battery saver mode light flashing, indicating the controller had detected battery voltage below 11.5 V. Up until this point I didn't think there was anything wrong with the bike but then I got a bit worried.
I did a good search of the forum and performed the tests advised to check the Voltage Regulator. Here's what I've found: All wires from the VR are fine as far as I can see. Battery voltage with bike off: 11.6 V, voltage at idle with lights and grips off: 12.2 V, voltage at 3000 - 4000 RPM with lights and grips off: 12.4 V, voltage at 3000 - 4000 RPM with lights and grips on: 11.6 V, battery dropped to 8.5 V on startup.
It seems like the VR is gone bad (and battery not great either) based on what I've read on the forums, but is this definitely the problem before I spend about €100 on a replacement part or is there anything else I should do?
