Electrickery, and where to find it ?

[oblertone]

I am trying to refit a Bike to Bike system (Intaride) that was previously wired straight across the battery. Can anyone point me at a convenient 'switched live' to power the unit and PMR radio. ie one that is only live when the ignition is turned on.

Under the seat of my '97 1100 there is a connector block (containing three Brown + colour wires) that goes no-where and I assume it's some sort of test point, can I use this to power the B2B as one of these wires (Brown/Blue) appears to be a switched live.

NO - that connector "block" is for the ABS diagnostic plug .

The brake light line is usually the easiest to find, use it to activate a relay to feed the radio from the battery if the radios power cosumption is too high for the fue rating on the brake light

I recently powered my Autocom from the horn feed using the technique at the bottom of this thread:

Works perfectly

there is a feed to the fuse box

Off the top of my head I'm not sure which one it is. I think it was a green wire. It should be easy enough to find. Beg borrow or steal a little volt meter or make up a bulb with two wires attached to the contacts, preferably soldered. If you're careful you can pop out the fuse block enough to get to the underside then test each connection underneath until it registers 12-14 volts on the meter or the bulb lights up with one wire to earth, the other on the connector in the fuse block. Do this with the igntion on first, when you get a reading leave the wire in place and turn off the igntion. If the meter drops or the bulb goes out you've got your live switched feed. then use one of them scothlock connectors or splice into it for a feed off.
