NC 30 electrical fault - (not common)

[bizzle3]

alright!
Ive suddenly encountered a strange electrical fault with my nc30. the last i remember, i had started it up fine and all electrics were working, i turned the headlights on and after it running for a while, switched the bike off, however i did not switch the headlights off. when i turned the ignition back on a while after, there was no electrical power that would usually light up the oil and neutral lights. nothing worked! the obvious solutions were explored, charging battery, changing starter solenoid, changed all fuses and i even changed the ignition ( unplugged old one and plugged new one in) tried all of this and still no electrical life. i then read a few threads on the low beam relay, i dont think the bike had one fitted and wondered if the switch had blown, would this mean there was a break in the circuit - hence no power? also when i changed the starter relay my socket accidentally bridged the live and earth wires, which start turning it over, but no fire up. any ideas? any advice is gratefully appriciated as always.
cheers

I don't quite understand what your issue is now,

Is it that the bike is totally dead, won't crank over when you press the button and you have no lights on the clocks?

It wont fire up by bridging the starter relay unless it the ignition is turned on and the kill switch isnt engaged.

With a broken headlight switch caused by wrong headlamps you should only loose headlights, the bike should still work and oil / neutral lights come on.

Time to get the multimeter out.

Check the battery voltage first of all, then the obvious like the earth is conneted.

You said you changed all the fueses, did you change the main fuse too, its in the connector for the starter relay.

If so get the wiring diagram if you dont have it already and start by checking that there is power going to the igition switch, and then power leaving it when you turn it on.

Dead main fuse..I reckon.

As above, check the main fuse, take the rear cowling off and it's near the rear brake fluid reservoir, I think it's 30A? Can't remember.

Failing that, get a light up screwdriver or a continuity tester and work your way around the loom seeing where power stops.

yeh, changed the starter solenoid and the 30A fuse already. reason i changed it is that when i use a light up screwdriver, it didnt light up anywhere else along the loom after the starter solenoid, hence why i changed it and still nothing. when i bridged the two together, was just by accident but has reassured me that the starter solenoid and main fuse is all intact and its somewhere else in the loom. yep cheers pal, might have to resort back to the diagram and give it another go. let you know how it goes.
thanks guys

Your unintended shorting of the starter relay does not confirm power is available at the main fuse, the two are not related.

Do you measure 12 volt dc on the red/white wire at the rect/reg, this wire connects directly to the output of the main fuse.

[Neosophist]

Start solenoid has a direct connection to the battery, shorting it out does not use the main fuse has magg as said.

All you have proved by that is that the starter is connected to the battery, the stater motor is correctly eartherd and the battery is somewhat charged.
