Solve the Mystery: Where are Couplers #2 and #5?

[El Cajone]

I'm having some electrical problems which I'm pretty sure are coming form Coupler #2 or #5 ("coupler" is Yamaha's word for "connector"). Can anyone tell me exactly where these connectors are located and what panels I have to take off to get to them?

So far I haven't been able to find anything definitive in the FSM or in Forum search.

The 2006 Service manual refers to couplers 2 as wire harness= front cowling wire harness and coupler 5 wire harness front cowling wire harness.

El, I got your PM and see this again in a new thread. I have handled every connector up front on my FJR at least twice but in spite of that I can't tell you where these two connectors are located The common place for the transition between the main harness and the secondary front harness is under the tank at the steering stem and under the right side fairing.

One thing I have found to be true with the FJR when coupler hunting -- just go ahead and take off every panel and take off the nose because the bustards are always hiding behind the last panel you take off, no matter how you work it.

Perfectly logical. When you've found it, you don't take off any more. So it was under the last one you took off. Always .

Thanks guys. I'm becoming resigned to my fate; that is taking off all the panels and checking the connectors one by one.

Just like troubleshooting in electronics, it's always the last thing you check that turns out to be the problem.

Time to bite the bullet and check all of them Dana. Sounds like Tech Day is a bit too far out to help you!

Good luck.

Proved this theorem again last weekend while tracking down an intermittent short affecting my driving lights and grip warmers. Absolute last wire I fished out of the depths of the front right side and down to the running light was pinched inside the cable sheathing. Almost no visible damage to the sheath but the wire insulation and the wire inside it was almost destroyed. The slightest movement of the wire caused an interruption of current flow. Traced every wire, connection, relay and fuse from the left front all the way through the fuse box under the seat all the way back up to the right front before I found the problem under the last panel I removed - the little triangular one the inside of the lower front right plastic.
