Proper soldering! :bow:

I love that soldering iron mate, it's a 125W Henley Solon I found in a part-demolished workshop. Must be 50 years old I guess but works perfectly and is great for heavy conductors. To make the junction block I drilled 9 smaller and 4 larger holes (1.5 and 2.3mm I think) in a piece of brass rod then cut almost right through it with a hacksaw so that it wouldn't conduct the heat away and could be snapped off after soldering. That big iron heated it up to soldering temps in about 5 seconds :)

My money would be on the starter motor.

Had this kind of issue before on a ford focus.
Wouldn't start on the key but would start with a bump.

Turned out the starter had gone faulty and was using too much current to turn the engine - this extra current was starving the fuel injection and spark system so it wouldn't fire on the key.

I guess it could be that. Strange how the fault manifested itself from the bike going down on one side in a slow-speed off. Can't think how that could affect the starter but stranger things have happened.

It's possible the brushes were on their way out and the fall was the final push needed.

Do you not have anyone local that could lend you a starter to try ?

Actually going back to earlier today, we did take the lead off the solenoid and used jump leads off a second battery to spin the engine whilst leaving the new battery fitted on the bike to run the electrics. Any issue with current draw wouldn't affect the workings but it still didn't start.

So, I've been riding this around for a month as it stands and has needed the 2nd battery to be charged twice. Not too bad really!

Currently, I'm going through the process of getting it boosted, so while that is off the road, I'll be looking into a charging system for the 2nd battery. Hopefully aiming to force the reg rec to switch which battery it charges through a relay of some sort.

Essentially, get bike running, during ride switch the relay to the 2nd battery. Aim to make it look pretty on the dash so I know current voltages of both batteries so I can switch between the decent one to the one with slightly lower power.

Doesn't resolve the actual issue, but without a test ECM to confirm or another starter motor... I can do zero @tu*
