Default vt 600 94 Electrical question... help needed

Finally getting around to finishing my hard tail conversion. Put the tank on to try and get her to fire, but couldn't even get the fuel pump to kick on?? Does somebody have a wiring diagram or pics of were the ignition coil and fuel pump plug in? Struggling and annoyed. The bike turns over, has headlights, turn signals, but I'm confused on were the factory connections go.

ttt... somebody... I cannibalized the stock electrical location, relocated battery, etc. Did I lose something? I put a test light into what appears to be the correct connection in the wiring harness, and tested with a test light. Key on and nothing was hot. Thoughts?

Nothing was hot at all?

Have you checked the 30A mail fuse? it's not in the standard fuse block. It usually somewhere around the starter relay.

I'll take a look at that. The lead off the rear coil pack is hot with the ignition on. The bike turns over fine. As I said, the headlight/front turn signals all work, even the horn. It was a running bike before dissassembly 6 months ago.

I have two male connections and two female connects (identical plastic connections). The male connects are from the rear cylinder coil pack and the fuel pump. The female connections are from the rear foot brake sensor and the main wiring harness. It seems odd that the lead off the rear coil pack would connect to the rear foot brake switch. Fuel pump to main harness makes sense though.

I currently do not have the rear brake light/blinkers hooked up, would that make a difference?

Try this for starters. You need an electrical schematic for the colors of the specific wires. Or, match up the colors of the wires in the unknown connectors. If a given wire is two toned (has a strip), normally one of the colors should still match up with its proper mate. Another option is a continuity test if you have a voltmeter.

Thanks! I guess my question is, where does the red circle connection connect?

I don't see it on the diagram, but you should have a fuel pump relay somewhere in the harness that is either making a poor connection or is junk. That will stop any power to the fuel pump.

I'm not sure about your particular model, but on mine (1100) the fuel pump will only get power if the engine is turning over or running. That being said, you may need to check your testing procedure?

thanks. I'll check it out tonight. I guess I assumed that the fuel pump would kick on when the key is in the "on" position, similar to my street bike.

I see what was puzzling you originally. The unknown P-connector shares the same branch from the main harness as the rear ignition coil connectors. However, that does mean they're related. The connector should plug into something within or something that extends within it's radius if that points you in the right direction.
