Expereinced something strange with the display on my '10 848 yesterday.

Shortly after the low fuel indicator illuminated, I pulled into a gas station to take on fuel. When I looked down at the display, the yellow service light was lit (along with green neutral and yellow low fuel).

I turned the bike off, fueled up and restarted with no problem. The service light stayed off and everything functioned normally.

Fewer than 5 minutes later, I noticed the backlight of the display was flickering. During periods where the backlight was out, the turn signal indicators (green on the dash) would not illuminate. It was mid-day so I couldn't see if the turn signals themselves were working. The display continued to show speed, revs, temps, etc.

When stopped at a light, I noticed that the headlight would also turn off during these random outages of the display backlighting.

Finally, the service light sometimes illuminated during these episodes. Perhaps as frequently as one out of three times it lit up. I was unsuccessful at displaying a code as each time I noticed it, it extinguished before I could cycle to the code.

So to recap the symptoms: Bike running fine, display accuratly showing all of the parameters it should be. When display backlight intermittantly goes out, the row of idiot lights at the bottom of the display do not illuminate and headlight goes out.

Clearly I'll undress the bike and check connections, fuses, etc. but given the history with these bikes and the VR, I'm wondering if anyone has seen symptoms like these. Many of the VR threads speak of similar symptoms but none exactly like this.

Thanks!

So I removed and inspected the VR - it looked fine. Do they generally melt or distort the expoxy when they die? I suspect that is not always the case. I cleaned contacts and various ground connections then reassembled the bike. I couldn't get the condition to repeat but I'd imagine that if the VR is on it's last legs, I'm due for a suprise.

Wanted to close the loop with you guys on this.

Shortly after our VR discussion above, I pulled the bike out and attempted to start it. Engine turned over very, very slowly but eventually started. Interesting because the tricke charger and voltmeter indicated a full charge.

Realizing that the battery was 4 years old, I opted to replace it before investing in a new VR. Happy to report that she's been running perfectly for a couple weeks now. VR delivering low 14 volts consistently and no weird outages or behavior from the electrical system.

Also interesting to me is that the old battery is still throwing 13+ volts on the bench. Very low amps when connected to a load so I'm assuming it must have a bad cell (or whatever AGM batteries have these days).

I was quick to want to blame the VR but glad it was just a battery in the end.
