Re: sunnys ac-dc and some picts of yesterday ride

Here's a link to a 12 volt rectifier circuit. I was using my old pull start
Arctic Cat 440 for trail work and needed to power a 12 volt DC strobe light
for safety. I built this circuit, powered it off the taillight wires and it
worked fine for the purpose.

If powering a GPS, be aware that voltage requirements vary greatly. You
could use the 12 volt power cord that was intended for your GPS or design a
circuit to produce the required output voltage.

It might work - depends on how your adapter was designed, but if it's 3V
out then 5V in *might* be enough to drive it. Trying it shouldn't damage
anything.

I cut the cord and soldered on inline plugs & sockets, so the adapters
stay with the vehicles and just the GPS cradle moves back and forth. That
was a lot cheaper than buying a second cradle.

On second thought, if you want to use your 12V DC car adapter on a sled,
the best way is to just add a bridge rectifier, filter capacitor, and 12V
outlet to your sled and plug it in.

Why didn't I do that? Because my GPS has voice announcements for routing,
and the speaker is built into the car adapter. I figured the speaker would
not last long outdoors in winter.
