Morning all,

Hoping for a bit of help from people who are a lot more technical minded than myself.

I'm currently unable to get my 600 Bandit to start. At present when I turn the key, the neutral light flashes on for a split second then dies, and I have no power. No indicators/headlights at all, and the ignition wont turn over at all when pressed. However the heated grips I have fitted do have power and turn on as normal.

I've started with the battery and taken it out and fully charged it, and its showing as being fully charged and working okay going off the charger. I've checked all off the fuses and they are all in working order, no issues there (including the 30v one). I've disconnected as much off the wiring as I could and cleaned out the connectors and reconnected everything but no joy.

I was hoping for ideas off where to go next? The only thing I can think off is a connection somewhere between the battery and starter?

Any ideas/suggestions would be appreciated.
Thanks

I would follow both battery leads for good connections to the bike,
then i would check for power at the fuse box when switched on.
Also are the heated grips connected straight to the battery?

Hey Jaffa,

Yeah the grips are connected straight to the battery. With the leads, do you mean testing them with a multimeter? (sorry I'm terrible with electrical stuff)

Thanks

I would remove the battery and check if the leads have good connections to the bike.
Then as my first post.

Ignition switch. Try turning the key ever so slightly to the left (from the ON position) and see if that brings the lights up.

Testing what a switch does is better than twiddling / playing with it.

Fiddling it is testing it.

The neutral light flashes up when the ignition is turned on. This suggests the ignition switch is making a connection, then breaking it. I have seen this before when the contact plate at the bottom of the ignition barrel has moved out of alignment, so nothing lines up when the key is in the normal starting position.

It is possible to fix it by taking the ignition barrel apart, getting everything lined up, and glueing it in place. I wouldn't trust this sort of repair, I would instead replace the ignition switch with a pattern part from a seller I trust (wemoto or M&P). Chances are it is already a pattern part to have failed in this way, so any concerns about having a different key for the ignition switch and other locks are nothing new.

Thanks for the suggestion, I tried this last night and no joy, couldn't get anything to light up.

Although this time the neutral light didn't even flash on at all when I turned the key as it had previously. Tried it a couple of times and jiggled it around but still no joy.

Unfortunately as I don't have a light in my garage I haven't been able to test any off the wiring that Jaffo suggested so that'll be my next point off call at the weekend when I have some light and can see what I'm doing.

Does the bike still have the original headlight fitted?

Get a wiring manual and work out how to bypass the ignitin.

Does this bike have a neutral switch.
I’m guessing it does.
I had a 2007 fjr a few years ago, and that had a dry soldered joint on the gear indicator wiring and would have the similar symptoms .

No the original headlight had been swapped out before I bought it.

How would this prevent the indicators and headlights from working as in the first post?

get a wiring diagram and multimeter and go from there in a logical manner following the "power".

I suspect you have not involved the heated grips with the bikes oe electrics at all at all?

Was it misbehaving before, like the neutral light flashes when the handlebars where turn lock to lock, o=r lights playing up??

It may be that the oe loom has suffered work hardening, fatique then make and break contact in the area of the head stock, where the wiring flexes ever time the handle bars are moved.

wiring diagram, study, then follow the power using the multimeter being methodical.

Of course it may well be something very simple like a worn ign switch or BAD CONNECTION somewhere. Done any painting of the bike very recently??

Nope, the grips are just wired straight to the battery bypassing everything else. Up until it did this the other day, the electrics have all been fine, no issues with anything electrical at all.

I was kinda hoping it wouldn't be a bad wire somewhere, which does seem to be the general consensus. Time to play test all the wires

Then you should check the bundle of wiring behind the headlight because it's supposed to be packed in the headlight bowl out of the elements but there isn't the room in twin spots so it invariably gets wrapped in tape and crammed in the frame. Apart from the various plug connectors there's a large earth junction taped into the loom there and this can rot away causing all manner of electrical issues.

Thanks for that, i'll have a look at that first then, fingers crossed that's the cause
