Hello there!! I need help troubleshooting my Garmin Nuvi 265W. I just put a new accessory fuse box in my truck for my extra electronics. I attempted to hardwire my Garmin. I cut the wires and ran the positive wire to the 10amp fuse on the fuse box, and the negative to what I thought was a good ground. I left the little tiny whit wire by itself (I just figured it was a remote wire for the charger, or something that has to do with the red light on the cigarette charger that comes on when you plug it in). I plugged it in and the GPS showed that is was on battery reserve power. I figured I needed a better ground so I started to move the ground wire, but I forgot to turn the GPS off!! So when I began to mess with the ground wire it sparked a couple times and I heard a noise near where my GPS is, and it sounded like a fuse blowing. I checked the fuse in the fuse box and it was fine. I then realized the GPS had gone dark so I disconnected the it from the wires and tried to turn it on and it will not turn on. Now here is my troubleshooting thus far: I connected the wires back to the original cigarette lighter charger, and the red light on the charger didn't not come on when I plugged it in, and the GPS would not turn on...... I got my multimeter out and put it to the wires and found it read 5 volts. I then opened black rectangle (the place where it converts the wires from the cigarette charger to the connector that goes to the garmin) and I tested both sides of the chip where the positive and negative wires were soldered. They both read 5 volts. So, it seems like there is sufficient power going to the GPS, but it won't work. I opened up the Garmin and everything seemed fine to the naked eye. So, my main questions are: Do you guys think I ruined the GPS completely? Are there components inside the GPS I may be able to troubleshoot/test? Is there a fuse somewhere inside the GPS? What is that little white wire I saw when exposing the positive and negative wires? Thank you guys such for reading, and let me know what you think. Anything helps!! Thank you guys!! Jimmy
