Long involved story but bare with me on this.
A week ago I'm on a ride and about 25 klms from home I get a puncture, no problem I carry 2 spare tubes.
As luck would have it, both tubes (brand new in box) won't inflate so I had no other choice but to start walking/pushing the bike home.
Yes I could have waited for the GF but I would have froze to death with the wind chill.
I end up pushing the bike (with the power off) around 10 Klms before the GF arrived and gave me a lift home.
All good, next project on the cards was to upgrade the rear brakes, as the brake line is internally routed I needed to pull the battery and battery mount out to gain access.
So fast forward and I have brake line routed, battery mount and battery reinstalled, hit the power button and nothing happens, the display is dead.
I then back track everything I have done, no damaged or crimped wires, so reassemble the bike, finish the install, bleed brakes etc, confident it's not something I have done.
So a bit of googling and it seems possible that the batteries in the Purion display might need replacement, I also discover that there is a battery activation switch accessed from a pin hole on the battery cover.
(this becomes relevant later)
It is suggested using a small allen key you can access this switch and it will activate the battery which in turn activates the display.
I do all this along with replacing the batteries in the display, nothing whatsoever is happening, bike is dead.
I should mention that while I had the battery out I was able to connect to the power plug which the battery connects to when it's in place in the frame, I could then observe what the led lights were doing.
So pushing the power button on the display the led lights would come on the battery for 5-10 secs but the display stayed dead.
Likewise, pushing the power button on the battery through the access hole in the cover, leds would come on for about 5-10 seconds before going out.
Today being the 3rd day of this debacle and I'm convinced I'm doing a trip to the LBS.
So I go out to the garage in what I think is going to be a futile attempt to turn the bike on and F!@K me, it powers on.
The display is working as per usual before ERROR 680 comes on, WTF is this, back to google but there is no error 680 listed on the Bosch web site.
More googling and seems to be a battery issue, more precisely the switch on the battery.
Next step is pull the battery out and remove the cover to identify this switch and see what's going on.
I'm no electrical expert so excuse my terminology if it's not correct, basically it's just a rubber membrane with a small square piece of metal underneath it, when you depress the switch it completes a circuit on 2 copper terminals which are imbedded in the battery case.
So back to before when I accessed the switch through the pin hole with the small allen key, I damaged the switch so it was staying constantly engaged with the terminals.
This was my bad but in my defense, as nothing was happening while I was pushing the switch and there was no real feed back of if I was making contact, I have obviously pushed too hard.
In summary, I removed the small square piece of metal so now the switch is ineffective but in all honestly it is superfluous as unless your display batteries go flat, you never need to use it.
I have reinstalled the cover, fitted the battery back in the bike, it turns on and off, times out and turns its self off after 10 mins with no more error 680 on the display.
What caused the bike to shut down and not be responsive I have no idea, I have emailed Bosch and await a response.
Sorry for the long post but it might help someone out in the future.
