First of all hello everyone. First post on here isn't a happy one unfortunately.
Basically turn ignition on, everything comes on as normal, fuel pump works fine, but when I hit the starter button..... nothing. It doesn't even crank over. No clicks from the battery. I've had the starter assembly apart, everything's fine in there, checked all fuses and bought a new battery. Still no change. Also there are no error codes on the dash. I'm not exactly very mechanically minded, so any help would be greatly appreciated.
Oh and just to add, bike bump starts just fine and runs as normal.
One other thing I just thought of. When it first occurred, I just held the starter button in and after about 10 seconds it did turn over and start. Ever since though, nothing.
You can also bypass the relay to help diagnose - just put a spanner/wrench across the 2 big terminals. This bypasses the relay and puts the full current to the starter. (quoted from anparkinson)
New starter relay installed. Still the same issue. No error codes showing, bypassing the relay gets it cranking. Ignition on normally and absolutely nothing when I hit the starter...
Check the wires giong into the starter relay. I believe you should be getting 12v from the red and red w/ white wires, and the blue w/ white should be giving you a good ground.
Spray, I don't have a multimeter. I'll get one at the weekend and let you know.
If it is indeed the cutoff relay, what would be the next step (looking ahead)? And when I say that, again, is it as simple as just replacing the relay, where exactly is the relay located? Like I said, I probably sound like a complete numpty here but electrics aren't my thing.
The cutoff relay is part of a larger assembly. The "#13 relay unit" contains both the "#14 starting circuit cut off relay" and the "#15 fuel pump relay". It's one of the more complex areas of wiring, and can be sort of tricky to diagnose. I'll admit I have a pretty good handle on automotive wiring, but I find this part hard to follow. Some wires disappear into the ECU and it's hard to say what's going on in there.
From a high level it's responsible for making sure the bike only starts in certain circumstances. If the bike is in neutral it should always start. If the bike is in gear, the clutch needs to be pulled in AND the sidestand needs to be up. It could be something simple like the sidestand, clutch, or neutral switch have gone bad. It's also possible the cutoff relay itself has gone bad, however the ECU does have some wiring to detect that the cutoff relay is present and working properly, so I'm not sure how likely that is.
In any event, I wouldn't recommend replacing anything until you're fairly confident there is a problem with it. You can end up spending a bunch of money, have a bunch of extra unnecessary parts, and still be where you are right now. Start with the multimeter. There are a ton of videos and articles online explaining how to use one. You'll need at least the DC voltage and continuity settings. Start by checking the red w/ white and blue w/ white wires going into the main starter relay. I believe there should be 12v on the red wire, and a solid ground through the blue wire.
If that ISN'T the case, then I would start by checking the clutch switch, sidestand switch, and neutral switch. Clutch and sidestand can be easily done by testing continuity. The neutral switch is as simple as seeing if the light on your dash is illuminated when you turn the key.
I know this a 2 year old thread, but did you ever get it solved? Im having the same issue and seem to be stuck.
