Model of bike?
If a ground wire burns and the fuse doesn't blow,it normally means the seat base is touching battery -VE terminal.You can burn a lot of ground wires like this,if the fuse is on the -VE side of the battery.
If the fuse is on the ground side of the battery,the fuse blows before the wires burn.

Sorry, '68 TR6R.
The seat is up and the wire that is getting toasted is from the rectifier to the battery and around to a ground on the front of the battery case. I just put the grounds back the way I got them, but I don't know it's right and the diagrams are leaving me a little fuzzy.
Thanks.

According to the wiring diagram for export models from DU66246 to DU90282 (1968), there`s no direct connection from the battery to the rectifier.
Starting from the battery negative (-), a brown/blue goes to the fuse and then to the ammeter.
Through the ammeter, then it changes colour to brown/white. and further on to the ignition switch.
The ignition switch has another link (br/wht) which goes to the bridge rectifier (-ve).
Here there is another brn/wht link to the zener.
Remove the fuse and with the ignition switch OFF, multimeter on the resistance (Ohms) range, measure the resistance at the brown/white wires.
Should be a few Kohms. [in other words not a short circuit]
All earth (+ve) wires are red.

*Note
I does not matter where the brown/white wires have double links, as long the connections are made between the rectifier, zener, ammeter and one side of the ignition switch.
In the above state [fuse out, ign off] the only earths to concern you are the rectifier + and the zener cathode, stripe. [earth---|<---brn/wht]
