Gpz500 electrical issues

[melons79]

Ok so i have a 91 Gpz500, been standing a long time, has no electric going to the well anywhere really, i've changed battery, checked fuses, replaced the wiring loom, solenoid, regulator, stripped all ignition wirring back but still no luck, i am about to change the ignition barrel, does anyone have any suggestions??

Have you been using a multi-meter to check that there is a current able to running through it for continuity?

Yes when doing that, the new battery i put on was saying it was completely dead, when i disconnected the solenoid it was fully charged hence replacing the solenoid, but still done it with the new solenoid in it, hence why i replaced the wiring loom as the connecting cap to the main 30A fuse was corroded, but still the same problem, i also have 2 little black boxes under the dash with prongs on which i am not sure why they are there as i havent seen them on a gpz before, also there was an extra wire connected in to the ignition wires which i took out and connected it all properly

There is a main fuse, seperate from the fuse box on the GPZ - have you checked this is present and ok?

Failing that, check with a multimeter until you get to where the power stops. If current's making it out of the battery, my money's on the negative terminal being corroded or loose resulting in no earth at all...

Yes checked all fuses including the 30A fuse that sits on top of the solenoid

Here's where you can get a copy of your manual for download just in case you don't have one!

Takes a little while to load up but once done it will download at high speed!

Still no joy the battery is brand new and yet when connected its saying its completely dead! when disconnecdted its fully charged so very confussed its beyond belief
