Mick - for the large gauge wires that connect to the solenoid, one from the battery is fastened to one of the studs, the starter motor lead is fastened to the other stud. (Think of each stud as being as a POS lead). I agree with Bryan, that "red" is homemade and the wire should be much thicker. The stock Honda lead for the solenoid studs is a terminal "lug" connector, using 6AWG (metric equivalent).

Still on the solenoid, here is a closer look at the red wire that splits into 2 ways and the starter lead I believe should go on top of the 2 way split red wire?

Check out this schematic, shown in hand drawn.

It doesn't show the 2 connections (black and red) coming from the middle of the solenoid.

I looked at OTP's last photo and it looks like the way I describe it as above?

Tell me am I correct?

Hey Mick, let me know if these help you. I can grab you some more pictures tomorrow if need be.

Here you've got the starter going to the left side of the solenoid also attached there is the fuse connection. On the right side is the positive lead for the battery.
(EDIT: fuse connection is on the right side with the battery lead)

On the opposite side of the bike you've got the negative battery ground lead coming off of the the rear engine hanger bolt.

OTP thanks for your help, I think the solenoid is correct? Your earth is blurry and I can't tell on the iPhone.

A couple of more photos would be great.

Sorry, it's a bad picture, I'll try to snap another one on my way out to work.

Thanks OTP, now I know.

Cal thank you for the regulator, it arrived, better than the one I had.

Don't mention, glad I could help!

Is this correct?

It looks like yours OTP.

MickB · « **Reply #735 on:** June 11, 2015, 01:28:41 am »

I've started the wrapping process.

bryanj · « **Reply #736 on:** June 11, 2015, 09:10:46 am »

Personaly I would get everything working first just in case there is a bad connection somewhere

I'll take a look at mine for you when I get home from work and post a picture for you Mick.

MickB · « **Reply #738 on:** June 11, 2015, 12:54:49 pm »

BJ thanks that's a good idea, but I checked I had continuity (power went from one end of the wire to the other) in all the wires prior to wrapping.
I hope it's still working after wrapping.

onetruepunk87 · « **Reply #739 on:** June 11, 2015, 03:41:52 pm »

Here you go Mick, pictured left on the solenoid is the connection coming off the starter. On the right side is the positive lead to the battery as well as the fuses connection. I think I wrote that backwards yesterday when I posted pictures (sorry it was right after I woke up) but yours appears to be correct to me. I'll go back and add an edit to my post from yesterday morning.

MickB · « **Reply #740 on:** June 11, 2015, 04:58:40 pm »

I reckon you're spot on OTP.

MickB · « **Reply #741 on:** June 12, 2015, 12:47:03 am »

Does it matter which wire goes on the flasher unit? Black and grey.

Tomorrow electrics on the bike.

bryanj · « **Reply #742 on:** June 12, 2015, 03:27:57 pm »

I does but you wont damage anything if they are wrong, just wont work

MickB · « **Reply #743 on:** June 12, 2015, 03:29:16 pm »

Too easy. Thanks.

MickB · « **Reply #744 on:** June 12, 2015, 09:24:07 pm »

Electrics in place and battery hooked up.

I wanted to trial the starter motor which I know is fine (had it spin before under power) - nuttin, not a cracker!

Could the solenoid be shot?

I've pulled the starter out and I can't get it to spin even when I connect it straight to the battery! Going to see if it works on an emergency battery pack designed for jump starts.

I'm positive all the wiring is correct as I followed each colour to its corresponding colour and where they meet at the connectors on the plate.

Any advice?

BJ looks like I should've left the amalgamating wrap off as you suggested.

calj737 · « **Reply #745 on:** June 13, 2015, 06:09:19 am »

He definitely jinxed you with that recommendation

bryanj · « **Reply #746 on:** June 14, 2015, 01:52:20 am »

Does the solenoid "Click" when you push the button?

Instead of taking the starter out just put the jump pack to ground(neg) and the starter wire at solenoid(pos)

If starter spins then and solenoid clicks could be bad connector bar inside

MickB · « **Reply #747 on:** June 14, 2015, 03:30:44 am »

Hey BJ I think it's a bad earth but I've pulled the starter just to check it's working properly (it was when I restored it), I'll know more in the next few days.

MickB · « **Reply #748 on:** June 15, 2015, 01:24:02 am »

Good news the starter is in good condition and works fine, next check on the earth and the solenoid.

bryanj · « **Reply #749 on:** June 15, 2015, 02:15:09 am »

The starter need to ground via the big wire at the engine plate ---thats why you need to take the paint off, the loom grounds via a small ring terminal up by the coil mounts so you need to remove paint there as well
