No feed to starter relay

[GerryC]

I'd be delighted if this is a "Hitler" question but am getting nowhere on search.
Bike (2005 GS1200) was outdoors on Sat night last in cold foggy conditions. Yesterday morning on thumbing the starter button a wee sound as if the starter turned 5 degrees was all I got. Battery was good - so good that (after much head scratching & thinking) hot-wiring from the battery to the starter solenoid got her going & home without issues or warning lights.
I ran the GS911 on it today & it reports fault 10233 "starter relay driver". Hot-wiring to terminal 30 (feeding the output circuit but not triggering it) on this relay allows starting on the button. Investigations suggest that the side stand switch interrupts the starter relays input circuits & all appears well here - the input circuit triggers the output switch but there is no current for that switch to pass onwards unless I hot-wire as above.
So I chase the red wire into the loom but where does it come from on it's journey from the battery - where do I look next - please & thanks?
Obvious answers that make me look real dumb are OK so long as they are helpful.

Crap pics Gerryc but may help some. Need better ones just ask and I will try harder.

Try this as its more clear

That's helpful thanks.
The red wire to terminal 87 (not 30 as I said above my mistake) comes directly from the battery & my red wire is dead - guess its a fractured cable somewhere.
New wiring loom so or perhaps a more permanent hot wire bypass bodge.

theres loads of stuff on here about this issue relating to side stand or clutch lever switches, make sure these are ok before ripping the loom open

I assume your gear position indicator is ok too?

I suspect there is a junction for battery ZFE link. Surely your situation lays there. Where that joint is I dont know. Would it be a connector block near the main feed from your battery? Sure someone will assist whoes spark wise.

Gear position thingy changed last year & reasonably happy all OK with the side-stand & clutch switches but electricity is not my specialist topic - there's no smoke escaping; always a good sign

A heads up on where this junction is hidden would assist. I'll investigate further tomorrow & use a bigger hammer
Thanks for taking the time & for the readable wiring diagram.

Have come across this before main feed from battery to starter relay cable broken in loom.
It is a 1.5mm cable. BMW insist on running the looms so tight !!.
Run another cable from the battery to the relay, I have cut the looms open before but there is no cable length spare to effect a repair.

That stacks up with what I'm seeing & your conservative treatment regime - avoiding heroic surgery - is what I intend to implement.
The worrier contained within will be wondering what further cables may fracture - bike osteoporosis?

You "can" repair by splicing in an extra bit of wire. But soldered joints are brittle compared to virgin copper and you'll need more heat shrink sleeve.

BTW Renault cars have the miserly wire lengths. My injector leads can't be unplugged individually. The wires are just too short.

Sorted

All OK again - thanks for help. Feed to relay bypassed & new wire contained in a bit of clear tubing - might avoid fireworks? Thanks for help - I was reluctant to bash ahead for fear of upsetting the canbus god.

Great to read your all sorted now. No doubt this will be valuable assistance to others in the future.
