Ok, so I wired up a connector into the tail light and grounded to the frame. I am on my second Garmin 60CSX. This time I plugged it in and everything worked okay for the first couple days then today the GPS won't stay on without holding the power button. I checked the voltage and I'm only getting 11.8 at the plug so it's not too much for it. Is my wiring not correct? Like I said, it worked for a while. My first unit I plugged directly into the sae adapter I have going to the battery for charging and the same thing happened.
