Potential electrical problem

[Groomerdriver]

I'll also post this in the electrical forum but I think I'll get more help here.

Sled is an 05 Vector ER with 8000 miles. Stator and battery replaced last season. Sled has NEVER done this before.....

I ran the sled yesterday and this AM without any issues. Right after lunch I started up the sled and it started and ran just fine. BUT...the gauge didn't work, I had no headlites, taillites.....nothing.

So while the sled was running I started to pull fuses to see of any were blown that might cause this problem. When I pulled the ignition fuse the sled quit (I expected this) and I put it back in. I checked all the other fuses and all were OK.

I then restarted the sled and EVERYTHING WORKED. I went out and busted powder for 30 minutes without any problems.

My guess is a connection is corroded/rusted/etc. and needs cleaning, but why did pulling fuses remedy the problem?

Any thoughts out there?

The load control relay supplies power to all the lights and gauge. It is activated when the ECU detects that the engine is running. Check the relay connections and if they look ok it might be time to replace the relay. You can also activate the relay and turn the lights and gauge on without the sled running by holding the thumb warmer rocker in the down position, turning the key to the on position and waiting several seconds while still holding the rocker down. The lights should come on.

Can you tell me where the LC relay is?

Is it near one of the footrests?

It's behind the RH foot hold plastic vent.

Thanks Grizz. Local Yami dealer has one in stock....$20. I'm very optimistic that this will take care of the issue.

wires

I know the RX1 had wire chaffe problems in serveral places.- same chassis as RS. I had one with my RX which was up in the nose where the wire harness went through the metal bracket that holds then nose together in front of the tool box. I have read about others in the frame area where the wire harness goes around the engine on the right side of the frame. It was VERY small and hard to detect almost like a razor slit.... The edges of that bracket had sharp areas...
good luck!

One other thing to consider would be corroded contacts in the ignition switch and due to cycling the switch back after stalling you made contact again this may be something to consider if the relay doesnt solve your problem I have a honda street bike that had a similar problem this summer

No, The ignition feed powers to the coils and load control relay through the same contacts. The engine runs but there are no lights which are powered through the relay so the ignition is fine. If all the wires and connectors are OK then it's most likely the relay. If the lights don't come on again the problem can be diagnosed by taking a couple of voltage readings at the relay. There should be 12-14 volts feeding the relay coil when the ignition is turned on and a grounded control signal from the ECU when the engine is running. If those are present then measure the output voltage to the head light and sig fuses (check these at the fuse box)
