Urgent electronics help please

[05062586]

Bike is a 2007 GS fitted with Autocom Super Avi and a Garmin Zumo 550. Riding along today and music from the Autocom disappeared and an hour or so down the road the Garmin powered down once the battery ran out ie. not getting any power from the bike.

Having got to my stopping point for the evening (Italy bound) it seems the Autocom is coming on with the ignition for a second or two and then powering off. The Garmin is getting no power.

So what should I be checking, the Autocom appears to be spliced into the power that runs to the accesory socket and the garmin takes it's power off the live battery terminal into a fuse which appears fine and shows 12 volts out with multimeter.


HELP?!

What's the volts to the other end of the cable(away from the battery)?

If the rest of the bike works then it's a broken cable or bad connectors.

Check ...

... the connection between your Zumo and the mount; you may find that the power 'pin' on the mount has worn away its contact point on the Zumo.

HELP?!

The Garmin powered down once the battery ran out ie. not getting any power from the bike.

the garmin takes it's power off the live battery terminal into a fuse which appears fine and shows 12 volts out with multimeter.

OK, it seems both devices are powered separately.

The Autocom, off the aux socket. This powers down after a few seconds. That is probably the Canbus detecting a short and shutting down. Check the wiring.

The Garmin, directly off the battery. That cannot be touched by the Canbus, as it is direct. I suspect that there is a break in the wire, or the fuse is loose, or the connection to the battery are bad, or the connecting pins in the cradle are dirty or broken. Ie. power from the bike's battery is there for a while and then it is gone.

It should be easy enough to fix. Start with the easy one. the Garmin directly to the battery. That should be straightforward. What voltage, if any is coming out of the non-battery end of the leads?
