Thank you all for your input. I really appreciate everybody here, you are all so helpful. I will check/all of these ideas. If your ever in the Pensacola, Florida area look me up. I live in Milton about 20 min drive to Navarre Beach. Thanks again.

Could it be the voltage regulator. I recently replaced this and was not the factory original? I'm still waiting for the factory original regulator.

Checked fuel hose and not getting any fuel? Suggestions? 

[scotty69]

I only found one 15 amp fuse between battery terminals. If there's more I can't find them?

[insanetexan]

Not sure how an efi fuel system works. My guess would be to pull the fuel line from the efi and turn the key on and try to crank it that way to see if fuel comes out of the hose. If there is no fuel that way then it would be somewhere between the tank and the connection as to why there is no fuel flowing. That fuel flow shouldn't have any thing to do with the voltage regulator.

There should also be more than just the one fuse somewhere on the scoot. Just that some of them are a real pain in the arse to find.

Here is the link to the wiring diagram on the boards;

Hopefully it works but those diagrams are showing 4 fuses for that scoot.

Thanks for the help which I need! I'll also be on the hunt for fuses. I know there's more than just one 15 amp fuse. Thanks again!

[scotty69]

I think I've isolated my fuel problem. Help! I'm getting fuel through my fuel line after it goes through the fuel filter. When I connect the line back to the carb it stops because it has to go up hill to reach the carb, then then the fuel stops. With an EFI/carburator I'm not sure what's next? Any suggestions? I put the line in a gas can and it now stopped. I guess that was the fuel coming from the fuel filter. Now I suspect the fuel filter?

Put gas can higher ten engine if it runs fuel pump failed or no power to pump see if fuse is inline and check

What you describe sounds like just the law of gravity. Surely with the fuel line disconnected, when you CRANK the scoot gas should come out of the fuel line in either continuous little spurts or a constant stream. If that isn't happening, either a serious blockage somewhere or a fuel pump that isn't pumping. If the latter, pump could be dead or just not getting vacuum or electricity (I presume the pump for an EFI system would be electric ...).

[scotty69]

I would love to check the fuse but I have looked every where, no fuse box? The only fuse I found was a 15 amp across the battery! I'm open to suggestions.

[ellpee]

Did you bother to look at the wiring diagram InsaneTexan posted? It doesn't tell you exactly WHERE, but it does indeed show a four-fuse fusebox somewhere, and you might be able to at least narrow down your search by tracing certain circuits. Mine, as I say, is under the seat AFTER you remove the little plastic "hatch" that gives access to the battery and some engine components, but that's an entirely different scoot. Seems to me on some other scoots I've heard it's up under the front plastic somewhere, but I'll leave it to the owners of other scoots to chime in with where their fuseboxes are hidden.

Mine is under the right floorboard. If the fuel pump is working correctly then you should get gas even when it pumps uphill. My Aeolus 300 pumps uphill. Scotty69, You live in Pensacola?. I live in Mobile Al. We aren't that far apart.

[scotty69]

Just to let you know I finally received an e- mail from BMS concerning fuses. They said I do not have a fuse box, only the carburetor version has a fuse box not the EFI version. It still bothers me that I have all those wires and there not protected! Thanks.

[scotty69]

Nice to know. My email if needed: [e-mail]. 

[cyborg]

That can't be right,,,, even a chimp would put a fuse block on it
