Has it really been 4 years ?!?!?  :o

Way to keep plugging along. Bike looks great!

Hope the electrical issue is easy to diagnose.

PS. I over-tightened the screws on my FT-CBR ignition switch & cracked the housing. It was very slight & I didn't notice at first. The bike would run fine & then just stall out without warning. It became progressively worse until I was able to see the crack. Replaced the ignition switch & all was well again.

A bit over 4 years already!  :-[
Of course the project lay dormand for quite a long time and I had to do everything without a decent workshop but still....

So far the electrical issue does not seem easy to diagnose.
When I turned on the ignition yesterday everything seemed to work as normal.
When I pushed the start button, power went out. I suspected a faulty fuse but none where bad.
Disconnected the battery.
I did a check on the starter solonoid wiring, disconnected and reconnected it.
Reconnected the battery.
Now when turning on ignition I do have power again. When pushing the starter button I only hear the solonoid clicking that I installed that turns of the lighting when starting. No other solonoids or starter motors are working.
I'm going to check that extra solonoid and see if there is power going through it or not.
Also going to bypass the ignition and I have a spare starter solonoid.
My fear is that I used too thin wiring throughout the loom...

Regards,
Paul

Verify that battery is up to the task.

Many FT owners chase their tail over non-start issues due to a faulty/weak battery.

And also check for bad earths and loose terminals.

I still have these electrical gremlins that I just can't seem to figure out.
My whole electrical system will just turn on and off without any apparent reason.

I've made a short movie to illustrate.

So the ignition switch is on, when I rock the bike back and forth the electrics start going ape shit.
Anyone any hints to what it could be?

You must have a loose connection somewhere, or a short to earth.

Haven't posted in a long time and this was mainly because the bike wasn't running and I didn't have time to address it.

Spend some time on it the past few weeks and did find a couple of electrical issues.
The starter control unit seems to have died. I've connected the yellow black wire directly to the green red effectively bypassing the SCU. I don't see the purpose of that thing anyway...
Next to that I ran another ground wire directly from the battery negative and that seems to help a lot.
The starter motor spins now, all the relays work as intended but it seems like there is a (mechanical) problem between the starter motor and the pinion gear.
I think the starter motor bearing is so worn out that the motor doesn't engage with the Gear between the starter motor and the pinion gear.
I know this bearing is a weak spot so will try and source a replacement. Anyone know the correct type?
Does mean taking of the complete left engine cover to reach it though :(
Next to that I think my battery is dying on me.
After 2 or 3 start attempts it will not be able to get the motor to turn anymore. It doesn't slow down or anything but it just more or less shuts down.
I can still hear the relays clicking but the starter motor doesn't turn and the cockpit does a restart sequence as if I switched of the ignition. I think it does this because the battery cannot handle the required starting current anymore.

Anyone more thoughts on this?
What other than a worn bearing could cause the startmotor not to engage with the intermediate gear? (Start motor shaft looks ok, some small wear marks. When I do not have the pinion gear installed the startmotor does turn the intermediate gear but as soon as I install the pinion gear it doesn't anymore.)
And perhaps some tips for the battery check?

Regards,
Paul
