  • GPS Spedometer Installation Question

    Hi everyone,

    Does anyone have experience with installing a GPS speedometer (Faria Euro type). There are 3 connections, one for power from the ignition switch, one for power from the battery, and a ground. Ground is needed, of course, but do I need to have the power connected from the battery (listed as always on). I'm assuming the power from the ignition switch would be enough for power. Does the speedometer need to be always on?

    Thanks everyone.

    The "always on" probably refers to that pin always having energy, not that the GPS will always be powered up. It's typically used to keep enough power to the device for it to maintain pre-sets or a clock when the unit is turned off.

      Hi everyone, so I have installed and tested the GPS speedometer by connecting both positive leads to the ignition switch. It takes about 1 minute to locate the satellites, which is fine with me. No slow drain on the batteries with the "always on" direct connect to a live battery. Now I know my Mako 15 with the Merc Thunderbolt 800 (80 hp) will run 25 mph at 3000 rpms, and 30 mph at 3500. I think I can easily get 35 mph before I hit WOT. Hope this helps others.
