Neutral light

Why would my neutral light be staying on when the ignition is off?

Just started today.

Re: Neutral light

The 'earth spider' problem only applies to the 2006 - 2008 Gen II models. Yours is a Gen I and the wiring is different. I would do a search on fjrowners.com there is a huge amount of knowledge there. Could be a corroded connector plug.

Re: Neutral light

Would it be linked to the electric adjustable screen shitting itself on the motor way earlier and now doesn't work??

That’s hard to call....it’s possible I suppose. Those electric screens are fairly robust,I’ve only ever had to replace them on crash damaged bikes

Re: Neutral light

I agree with DavyH - unlikely to be the screen motor which is robust, but something to do with a connecting block or wiring in that frontal area. Seems a coincidence.

Quite possible. I was replacing the headlamp on one and scratched my head for a while trying to work out why the sidelights weren't working. The screen had to be connected in order for them to work. Very strange.

Re: Neutral light

Pull the backup fuse to see if the light goes off. That fuse and the signal fuse supply power to the screen drive where the neutral light takes its 12v power

Re: Neutral light

So I stripped it all down and found the aluminum bracket that attaches the screen mount to the worm gear of the motor is broken.

Would chemical metal fix this?

Also, why would this cause my neutral light to stay on?

Re: Neutral light

Did you pull the Backup fuse? Did the neutral light go out?
If so is there a 6 way connector going into the Drive motor? If
so separate it and see if the neutral light goes out.

Re: Neutral light

Replacement unit required I would think unless you can take it apart to check the electronic box. If it is resin filled it is unlikely to be repairable cheaply
What year is the bike?

Re: Neutral light

2002.

I was speaking to Eric in City Spares, looking for a new unit but I mentioned the neutral light issue and one of the things that may cause this issue is jump starting it from a car......which I did the day before.

Anyway, got onto eBay and found the only unit listed for 100 quid.

Fuck it!!!

When will I ever have a bike that just starts, run and rides 100% for ever??? Oh that's right, my CBR 600 did that for me before I sold the fecking thing!!!!!

Re: Neutral light

Didn't you have a sweet grey ST4 at some stage too? Or am I mixing it up with someone else?

I would have thought those FJRs were fairly well-behaved, lots pressed into service as cop bikes around that era.

Re: Neutral light

I have just checked this on a Gen II

if the screen is up when you turn the ignition off, the green neutral light stays on until the screen fully retracts, then the green light turns off.

So with your screen motor problem, the sensor that signals 'full retract' is not triggering. I think it is a reed switch near the bottom of the slide rails.

This is the link between the two issues.

Re: Neutral light

It looks like part of the motor body, I wonder why it broke, presumably the motor or some linkage seized.

Possibly could be repaired with one of those low temperature aluminium rods you see at shows.

Probably easier to replace the lot with a second hand unit, the electric screen is a good feature to have working.

Re: Neutral light

So, it looks like the module/control box/ecu whatever is actually fine.

I've tested the unit and motor and it's all working including the neutral light going out.

It looks like when the bracket broke the screen dropped and was stopping the worm gear from actuating the 'closed' micro switch and thus the unit was keeping the circuit live, draining the battery.

I have ordered the 2nd hand unit, so should be back in action next week.

If nothing else it's given me the chance to do a very bits on it that I've been putting off.

Thanks for the help all.
