I have a Tomtom one that I use and notice that the unit would turn off when running the bike at higher RPM. I could turn it back on but it would shut itself back off in a couple of minutes. I tried it in the car and it works fine. I also have a Gamin Nuvi 250 and it acts the same way. The bike is a new '06 wee with 2,000 miles on the OD. I still can use the GPS's but I have to use them on battery power then allow them to charge up when riding at slower RPM's. Other than the GPS problems the bike runs fine and I have other devices (XM radio) and never have a problem.

Hi

I had a few TT1s and have now a TT2, both versions are Riders, I am assuming yours also is a Rider.

If so, you may have a problem with the actual motorcycle mounting bracket. If you look at the front, where the unit clips on, you will see 4 holes where 4 screws hold it together. What happens is that where the screws are inset the plastic cracks or breaks, this means the screws are not holding the front bit of plastic down, which in turn causes the pins to NOT make a true connection and it will shut down when it runs out of power.

There are a few threads on VSRI about this with photos, but the forum is having issues at this time and posts are missing.

Have a real close look inside them screw holes, twist the bracket at the same time, see if that is the cause.

I wore out two brackets under warrenty, one TTR1 and they finally upgraded me to a TTR2 at no cost.

Cheers

You may be getting a vibration related open to your power, or possibly an overvoltage (regulator not regulating?). The voltage shouldn't go over 15.5 volts when rev'd up. The VStrom has quite noisy power, direct to the battery with the cable away from the coils, and injectors, is usually the cleanest power.

So I wounder what the voltage on the V-Storm would be a 6,000 RPM? Kind of hard to test. I never have the problem at slower speeds. I have two sources of voltage I can use and one does run close to the coil but both from the battery. I'll try using the other source. I would never have thought "dirty" voltage could cause this problem.

I have a Kisan chargeguard and the voltage at 6000rpm is just on 15V.

Your TomTom is not a rider so disregard all my comments about the model. I would still be checking where the contacts sit, because there design in this department is crap.
What does the contacts pads look like, are they indented in anyway, holes in them, maybe the pins on the TT are worn down from vibration?

Maybe I am comparing eggs with apples, but here is a picture of the back of my TTR1 after extensive vibration on the road


I am just trying to see if it is mechanically faulty and not an interference or electrical fault.

My Tomtom has a small like USB connection and plugs in very securely. I tried a different 12V outlet on Sunday and went for a quick one hour ride and that seemed to work. I was probably getting dirty voltage because the wire runs close to the coil. Thanks for your help.
