Newbie here, not a mechanic at all.
Bike: 1984 CBX750F
Location: Australia

Bike was running fine but I hadnt started it for 3 weeks and my battery was flat so I stupidly started my car first and then connected jumper leads and I heard a chk sound and the jumpstart didnt work. I replaced the battery, the main 30A fuse and all the fuses near the handlebars and nothing, dead, no lights nothing. I checked the voltage on batter and main fuse and perfect 12v but bike is dead.

Any thoughts?

Could be the relay, I'll update if so.

Update:
1. Replaced the relay/solanoid and it started straight away.
2. Then went dead again, giggled the ignition and it came back on.
3. Took apart the ignition switch and realised the whole ignition switch housing was loose.
4. Put a cable tie and taped it up tight and all good so far.

I'll look to replace the ignition switch housing, any tips for finding CBX parts in oz?
