Het guys, has anyone mounted a volt meter across their battery while riding before? what kind of range did you read? I'm thinking of wiring a few things onto the system but i dont want to fry them by having voltages too high. I can cope with under voltage but not over voltage.

well, you don't have to ride it .... just put your meter across the battery and rev her a little.

So what kind of things are you planning to wire in?

Ipod charger, cell charger, GPS, lazer guided missle control system, HUD? JK  :laugh:

There are no issues for wiring any automobile rated device/adaptor to your GS.
Just do a good job of the wiring size as related to the load (amperage) and you should be fine.

The GS charging system is barely adaquate for it's self.If you add much to it the charging system can't keep up and the battery will crap out,leaving you stranded.

Im planning on wiring in a little video cam which is rated at 12V +/- 10% but its not automobile rated as such. Im not worried about it drawing too much current, it only takes ~100mA, but i dont want to fry the bugger. Anyways, im just going to grab my multimeter and get revving and see where I end up...

You should be fine with that. The device is probably regulated internally. Anything over the rated input is wasted as heat in the power supply circuitry.

Of course if you put too much into it... poof, the maximum ratings show their practical limit.

If you run off the battery connection, with a fused on/off switch of course, you should be fine.
