How can I install the garmin 665 to my bike harness without damaging the garmin gps or my bike electric components. I want to connect the power cord to my battery directly. How should I go about...
I don't particularly recommend connecting your GPS directly to your battery. Hooking it up in this way puts you at risk for running down the battery, since the GPS will not turn off when you turn off the bike. You might be able to get the same solution by running a positive lead from one of the fuses in the fuse box. That would get you a switched power solution without necessarily complicating your installation.
However, whether you're connecting directly to the battery or through the fuse box, you'll need the same basic materials: a 12v cigarette lighter charger for your GPS and an in-line fuse to protect the GPS from power surges. Use a cigarette / 12v power port in your car to double-check the positive / negative assignments to each side of the cigarette lighter charger. Then, keeping track of those wires, cut off the charging end, so you have 2 bare wires. Add the in-line fuse (10 amp should be fine; 5 amp might be appropriate, too) to the positive wire. I suggest soldering the leads, rather than using crimp or pressure connectors; motorcycles have a habit of vibrating everything loose, over time.
Once you have your prepared charging line, run it down from where you plan to mount your GPS to your chosen power supply. Install the negative wire to ground by attaching it to a frame or motor bolt, rather than directly to the battery. This will be easier if you attach a loop terminal that fits between the bolt and the tightening nut. On the positive side, if you're connecting directly to the battery, attach another loop connector to the wire and sandwich it between the positive terminal of the battery and the primary power lead. If you're going into the fuse box, you may be able to sneak a bare wire in between one of the fuses and their fuse holder. Simple friction may hold it in place. A more elegant solution would be to attach that lead to the terminal with a dab of solder. Place your lead on the incoming side of the fuse, so that your power drain doesn't go through the existing fuse and blow it.
