Zumo problem

[kickstart]

Have just fitted an Zumo 550 to a 2009 1200GSA and I'm experiencing electrical interference through the headsets when I turn on the igition (not the engine). Its gets slightly worse when I start the enging but not noticeably so. The unit (autocom) is earthed to the battery negative and fead by the auxiliary plug live. All the cables are routed via existing cables but can't seem to isolate the problem.

Any suggestions would be appreciated?

Thanks.

Not sure if this helps.
On mine the two phono type plugs on the left of the Zumo were making a poor connection. It's worth giving them a wiggle to check. To cure this I added some solder to the plugs to make it a tight fight. It worked for me.

What lead are you using between the autocom and the zumo?

I had a smiliar problem and for me the autocom was too close to the battery, when I moved it away all became clear so the autocom is now under the tank instead of on top of the battery.
You don't say if you have the isolating lead from Zumo to Autocom fitted.

Sorry. Not using Autocom mine is an Interide unit.

TRY REROUTING YOUR CABLES HAD THE SAME PROMLEM MESELF, ONE OF THE LEADS WAS ACROSS THE ECU. MOVED IT AND IT WAS SORTED

thanks for the replies could be the ecu giving the problem will try again the marra.

Cheers.

Similar logic though I'd guess, make sure the leads are away from ac sources eg generator / ignition as this can induce interference. If you can, get really long ones and get them as far as possible from the bikes leads. One thought is the fuel pump / fpc producing the problem.

I powered / earthed my autocom from the aux socket using a plug with no interference problems on the two 1200's I had.

it might be worth thinking about the lead going between the zumo and autocom as someone else mentioned above. Autocom recommend using an isolated lead.

Especially if the Autocom and Zumo are powered from the same source, and it is unlikely that you are using 9V batteries in your Autocom. But you could see if the interference disappears if you run the Zumo on its internal battery.

Thanks for the replies guys - I've re-routed the power lead from the zumo to Autocom
away from the ECU, fuel pump etc and the problem is now sorted. Hats off to all of you and thanks for the response.
Cheers very grateful.
