Hi everyone,
I hope you're all well. I have some electrical issues and have a trip coming up that's putting a bit of pressure on me trying to fix it. I've been trying to resolve it, but have started running out of ideas.
In short my battery drains after rides of about 1 hour.
The longer version is as follows.
I did an off-road trip around Europe for 8 days and at the end of it my battery was knackered. My bike would die after short rides, so I replaced the battery with a brand new one but the battery issue remained.
So I started testing. I realised my stator was shorted, as there was continuity between the three yellow wires and the bike ground, so I replaced it.
Both before and after replacement my RR tested fine by itself for resistance between the 3 yellow wires and the RR +/-.
I replaced i my existing RR with a mosfet RR. However, please note that I bought 3 new mosfet RRs and all three failed the diode tests. All of them failed the quality checks outlined here before I put them on the bike. I returned two and was allowed the keep the third for free
My results:
I assume I should get a value between 0.09V and 0.11V for the first test instead of 0.266V.
I put the last one on regardless, as I assumed I must be doing something wrong and the seller said I can keep it and try it.
Come today, several months into the issue, I did the above battery tests after installing the new RR and went for a test ride of about an hour or two stopping occasionally. My battery (thankfully) stopped starting my bike at my last stop when I arrived home.
Just before arriving home my horn stopped working and the LAMP warning light came on for my rear tail light. Turning the bike off and on fixed the light, but the horn only honked very softly and shortly for a few times and then stopped working until turning the bike off and on again without turning the engine over.
I ran a few continuity tests for the stator and it seemed fine. After the bike sat for an hour the horn started working again.
I tested continuity with ground in the RR with the three yellow wires and the third had continuity. I'm not feeling this is an issue, but thought I'd share in case it is and I don't know.
I don't know what to do next.
I tested my new mosfet RR diodes with 4 different multimeters to make sure that's not the issue.
I don't know what's going on anymore.
Does anyone have any suggestions?
Thank you,
Yannick

However, my battery voltage would drop from ~14.00V at idle to 13.4 at 3k revs to -13.3V at 5k revs.

My results:
Meter Black to Mosfet positive1 or positive2 (each) & Meter Red to Mosfet R1,R2,R3
Diode Test (V): 0.266 0.266 | 0.266 0.266 | 0.266 0.266
Meter Red to Mosfet negative1 or negative2 (each) & Meter Black to Mosfet R1,R2,R3
Diode Test (V): 0.644 0.644 | 0.647 0.647 | 0.649 0.649

The charging Voltage is around 13.75-13.85V at idle and the same around 3-5k revs. The idle voltage pretty much stays to whatever the 3-5k revs goes to. When first started is was around 13.5V at idle and went up with the revs and stayed up. Around 13.85V after a few revs to 5k.
