SR Unresponsive
« on: October 15, 2017, 04:25:29 AM »

Hey, gang! Been a while. Unfortunately, my SR isn't very happy with me. I put it into climate controlled storage last winter. I left it plugged in and I checked on it a couple times and all seemed well. Several months later, I returned to find the GFI outlet had tripped and there was no life in the SR. Not even the battery LED. All dark. I finally made time this weekend to work on it before paying someone to haul it to the dealer. I downloaded the 2014 manual and removed the seat to inspect the fuses but I am not able to locate the charger fuses. They are not with the board and converter fuses as shown in the manual. All other fuses including the 4 low voltage checked out. Any advice before I start spending $$$ ?  Thanks!

Nobody knows where the fuses actually are?

Something is very strange.  Even if the outlet tripped, the battery should have remained at 100% for a long time.   So I don't understand why it wouldn't turn on at all.  The charge fuse doesn't have anything to do with that part anyway.  However, the fuse is in the wiring harness, covered in hard thick heatshrink just above the SBS50 DC output from the charger clipped to the right rear battery inside wall.  It's not meant to be serviced or even checked by the owner.  This is something that you need to take it to a dealer where they can pull the logs and find out what percent it was parked at on what day and follow the logs to see what happened when, because the bike should have no way to self discharge rapidly like that.  Even the BMS goes into hibernation mode so not even milliamps are used anymore.  A battery parked at 60%, should have over 50% a year later, although its always good to check.

I'm not sure what happened, but definitely don't worry about trying to check things right now, just take it to the dealer as soon as you can.

If the outlet has tripped, there has been something very wrong with the charger.

If the charger "decided" to short the garage's power circuit, this stupid charger may also have drained the battery, faking a "charge" so that the BMS would not shut down whatsoever...

@Terry did you intend to say SBS75X not SBS50?

Shadow the SBS75x is the accessory charge port above the motor
The SBS50 is the onboard chargers DC output, and the fuse is inline right above that

So I indeed meant the SBS50 and not the SBS75x

Although I believe you can remove one pin from the main battery Anderson, one pin from the SBS75x and one pin from the SBS50 and you can replace that part of the harness and it will have the charge fuse in that circuit.   But still just take it to the dealer and let them do it if in fact the charge fuse if blown which I highly doubt in this case.
