Charging Circuit
I'm making my own 'car' wiring loom to integrate with the bike engine loom in my 7 and was wondering how the charging circuit works
in the bike?
I have attached a simple diagram of how I propose to wire my fuses - the ignition-switched power goes from the battery, to the main fuse and then to
the ignition-switch. Whereas the permanently powered fuses get their power directly from the battery (as opposed to going through the main fuse and
then bypassing the ignition switch). I did this because there would be too much current going through the main fuse otherwise and all the wiring would
need to be uprated etc.....
As I understand it, the output from the alternator goes into the rectifier/regulator and then joins the output from the main fuse to power the fuses
when the engine is running. So would my permanently-powered fuses still get power from the alternator, albeit indirectly - ie. through the battery
terminal?
Cheers

I would connect the output from the rectifier to the other side of the main fuse!
Your method means the main fuse is being bypassed when engine running plus any charging load will be going through the fuse back to battery. Not very
safe!

Sorry, I should have mentioned - the above diagram is exactly as the bike loom is wired (including the position of the rectifier output) - the only
thing I have changed is that I have taken power to the permanent loads directly from the battery instead of tapping into the pre-ignition switch power
cable.
