So, I got my bike delivered last week. First trip, lovely...

Or so i thought....

Noticed that my dash was intermittently cutting out and I thought "SHIT, this is what happened on the Blackbird", possible reg/reg/stator failure. Bumped it half way home, died again. Luckily I stopped outside a pub with a group of men outside who has jump leads and a spanner to get the seat off (cheers Honda, great design there) and I have limped it home.

Just tested my battery, 11.5v, so that's low. I can't start the bike on the centre stand, so I need to get it off the drive to test it (plus it's too late now).

So I get under the seat and notice this...

It's a total longshot, but does anyone have any idea what could possibly be coming from the -ve terminal on the battery?

I have an alarm fob on the keys and asked the chap I bought it from if it worked, he never used it, he also said he didn't have any charging issues (but I'm calling bullshit on this..)

Sounds like Reg Rec failure. I can't see the pic though.

Fixed the image now.

I'd like/hope to agree as it's just a bolt off, bolt on job. But the Blackbird stator fried. Just need to do some more checks when it's dry out.

I wonder if a previous owner has bodged an earth wire?

The bike may have been layed up and untended for some time before sale. A weak battery will kill the charging system components too as they fight to resuscitate it. I'd get a new battery and fully charge it before use, or use a jump battery when testing the system.

I'm not mechanically minded, any reason why they might have bodged an earth? Alarm maybe?

According to the V5 he bought this just before summer. As the voltage is low, I'm going to buy a battery for peace of mind and might get a reg/rec as it's inevitable and I know that it's been done. Then just hope it's not the stator.

I'm not sure but it could be that the bike was playing up due to a corroded earth and instead of finding it they just created a new one, or more likely that's a direct earth between the reg/rec and the battery to improve the connection. Bodged in that the wires appear to have been simply wound together with no solder.

Does it have an alarm module?

The red crimp on the +ve post suggests that there is an Optimate charge lead attached,together with the in-line fuse holder.But I see no such connection for the Optimate lead for the -ve post.Maybe the blue wire was a bodged connection for the Optimate in-line lead connector?

I would be checking that if the blue wire goes nowhere,then remove it.Then check to see where the -ve post Optimate lead is.If you have such a charger then make use of the charge lead Thumbs Up Wink

Optimate leads use a blade fuse, that seems to be connected to a glass fuse so probably isn't an optimate lead.

I would guess that lead is for the non working alarm.

I agree.

I've taken the tail off and needed to lift the tank to get to the reg/rec stator connector. But it's been hard wired.

Is there any other way I can test the stator?

iirc its a plug in reg/rec so you can check it at that point.

I think you're right, I've googled it and it seems to be a Battery Terminal Ring Connector Harness.

SO I have replaced the reg/rec and stator (stator was also fried). Now when I turn on the ignition the fuel pump primes then doesn't shut off.
