I'm thinking of putting a voltmeter on a thunderbird 350 can I wire it to the battery terminals with a of on switch in the positive wire so I can switch it on when the engine is running and switch it of when its not

May be of help:- http://www.ehow.co.uk/how_5890563_wire- ... meter.html

There is no need for a switch; earth the negative wire to the frame, then find a wire that only has power to it with the ignition switch ON and connect the positive wire to that.

I don't know how RE wire their bikes but usually the horn feed is always "hot" when the ignition is turned on.

thanks for reply the horn feed sounds good and quite easy to get to if I decide to get one that's what I will do find a switched wire that comes on with the ignition like the horn or maybe a rear brake light etc thanks again

There is also a convenient live to the front brake switch, usually easy to access/connect in the headlight nacelle..

I found the easiest way to mount a proprietary gauge to my Bullet was on the right-hand indicator stalk. This is an oil temperature gauge.

once again thanks for the info would it be the same procedure to wire in an ammeter instead of a voltmeter

Never connect an ammeter across any voltage source...it is nearly a dead short, always connect in series...eg in-line with the wire feed to the item you are measuring the current flow to.
Most bikes bring the main power cable from the battery up to the headlamp and then distribute the power via the main switch within the shell or on the handlebar switches. You need the red? wire from the battery fuse that feeds the lighting /ignition switch so either cut this in a convenient place and wire the ammeter to reconnect the two ends otherwise run the two wire from the ammeter to interrupt this main supply at another convenient position.....Les
