+1 to the switched power source. If it can't draw anything unless the key is switched you can breath easy. Unless of course you leave the lights on again.

And, of course, leaving the lights on means you left the key in, ignition turned on. Vic, you're lucky no one rode your ride off into the sunset. Probably noticed there was no clutch lever and said "Screw this...I don't want a scooter!!"

Mebbe it was the huge Thermos mounted on the pillion seat scared-off the would-be thief????????

I'd put a 12v switched relay in place to turn off the GPS. $6 at the parts store. Just tie the relay in to a switched tail light to shut it down. The wiring is very simple and the whole job takes 30 minutes.

 
Thanks for the info Mojo. When I get back, I'll have a buddy who knows what he's doing to look into that. My track record with electrical things isn't very good. :)

 
Here's a diagram (it's a simple example) of how I installed the one on my bike. It's a closed circuit so I know that all of the connections are good.

In my installation, all splices are soldered and taped heavily. I used outdoor rated wire for good insulation. It's probably overkill but 12 volt can be nasty if it shorts out. I've got fuses strategically placed to eliminate any chances of burning stuff up should the insulator get compromised in the wire runs. The locations of the fuses are easily accessible for replacement or trouble shooting. The relay is under my seat for access and makes the connection to the running light easily done.

Net result? I have 3 additional devices that are switched with no chance of draining the battery if they are left on by mistake. All I've done is modify the harness to include them in the circuit on the positive side.

Good luck.

Thank You Mojo. Being that I'm not a complete electrical *****, that actually looks simple. Even I can do that. :)

 
Howie!! Why you messin' with my mello Bro..... Bite Me!! :)
So RadioHowie, who watches over majicmaker Vic when you can't find the time to do handle that chore? Walt? Gary? Tony? Redfish?
A little bit of all of the above, BEEMERDONS. I just got to SANFORD and I'm visiting with my dad at my niece's house. It's been a while. He decided to fly to Florida and pay us all a visit. He looks like a million bucks! He looks just like me except, he has no salt and pepper anymore. He's all gray. He's deep into his 80's and has 75 y/o girlfriend. When I grow up, I wanna be just like him! :))

 
Relays, for the people that normally don't get involved in sparkie games:

This is the schematic layout of a relay like the headlight relay. Only one contact can be closed at a time. Pin 87A is normally closed when the coil is not energized -- pin 30 is connected to pin 87A and pin 87 is open. When the coil is energized pin 30 toggles and connects to pin 87 leaving pin 87A open.

Most 4 and 5 pin automotive high current relays have a similar pin layout. If you look at the bottom of the relay you should find numbering and pin orientation like this:

If you didn't have an AE, I'd wonder why you didn't just try push starting it when the battery went dead and the pigtail wasn't charging it. But I'm guessing push starting isn't possible on an AE due to no good way to pop the clutch. Unfortunate.

I managed to drain my battery when I first got my bike up to NY.

Rather quickly learned how to push start the bike with the help of a slight downward slope in a parking lot.

Has run fine since.
