TT Mount & Power lead

[santrix]

Here's my prob folks, any insights would be appreciated.

I have a Starcom one advance intercom system on my F650. One TT lockable mount and a TT power/audio lead (with power converter).

The autocom is powered directly from the battery (it only turns on when connected to a helmet) and i have an MP3 player plugged into it.

I connected the TT power audio lead to the BMW aux power socket (the TT lead had this plug on it) underneath the left hand side front fairing. I also connected the audio cable to my Starcom satnav/aux in socket. I dropped the quest into the mount (it is a fiddly fit) and it seamed to work for a few mins then promptly destroyed the quest.

No master/forced reset would work, totally dead. back to garmin for replacement.

Now im thinking that maybe when putting the quest into the mount the 'wiggling about a bit' may have caused some pins to touch where they aught not to, does that sound feesible? or some weird feedback from the starcom1 through the aux socket.I still have the lead and am thinking of splicing it to add a switch, since the 12v supply from the socket is constant.

I dont wanto have to cough up for another wasted quest haha.

Any pity or advice would be appreciated.

Any pity or advice would be appreciated.

I was going to go with the "Pity" option, but I thought I'd give this a bump while I'm at it. The Quests are fairly robust, I'd be
surprised if any audio signal could feck it up, if the power contacts (the two on the RHS of the cradle) came into contact with
the others it probably would do serious damage. I know I saw a diagram of the pinouts for the Quest somewhere, I'll try to find
it and post it on this thread.
I presume you are using the Quests voltage regulator ?

Just looked at the date on this, have you tried it out yet ?

I believe that the TT power cable has a voltage regulator built into it.

I would make sure about that if I were you. I think TT might offer more than one type of lead. Did you fit it yourself? You didn't chop a plug of the end and hardwire it to the Aux socket by any chance? The VR may well have been in the bit you cut off if that's the case and you might be getting 12v where there should only be 5v. Have you tried a multimeter across the pins to determine the voltage output?
I've had a bit of a look at mine but not to the extent where I'd have to start removing the headlight nacelle etc. and as far as I can see and memory serves I just hardwired it off the pilot light circuit. Make sure you use the correct fuse, 3.5amp IIRC.

Where's Ram Man these days? He'd know the score.

All sorted.....

I had a look today - it's a 1.5amp fuse.
