GS1000 Fusebox Replacement - Upgrade?

[Skowinski]

Thanks Nessism, always open to hear thoughts and advice. The idea of doing this was to bring this old machine in line with all the others in the garage. It's the only one with the old glass fuses. Piles of blade fuses in the spares box, and they are also easily available when travelling.

I have a few of the Vintage Connections kits, and bought the roll-over crimping tool. Used it extensively when we restored the Honda CB500 as numerous connectors needed to be replaced. It makes very secure connections. One of the 8-pin connectors from the kit fits this fusebox perfectly.

I have the wiring for this GS750 fusebox figured out. I'll try to draw a better diagram than the current one scribbled on a grocery list, LOL, and post it up later in case anyone else is interested.

Here is what the GS750 fusebox looks like inside (main body on right, fuse side facing down). It's built up in layers that are held together when you put the back plate (on the left) on. Seeing this makes it clear what wires go to which pinouts, using the diagram posted above by JTGS850GL.



And, this is a drawing of the connector, looking at it from the bottom of the fusebox as in the second photo. The wire color codes and what fuse sockets they go to are indicated. Color codes for the 83 GS750 fusebox and the 79 GS1000 fusebox connections appears to be the same. Added Note: all pins go to fuse sockets except the "power source (-)" which is the screw terminal, and where a pin leads to more than one fuse socket they are listed, e.g. orange wire goes to 3 fuse sockets, headlight signal ignition. Upper right red wire goes to 2 fuse sockets, main and power source.

I guess you could reverse "main" and "main power source" and get by with it but I think I would prefer keeping them stock.

And B/W is harness ground as "power source (-)" is dangerously misleading.

Next thing is "what is the power source"?

Sorry, perhaps I could have been more clear. I edited the diagram showing what wires go to which pins, and added some info.

Power source (-) is the screw terminal (can be seen on the last photo above), it is labeled "power source" on the fuse block and has it's own 10A fuse. On the GS1000 wiring diagram this is a separate unit called "output terminal".

All other pins go to fuse sockets. Where more than one fuse socket is connected to a pin I indicated which by listing them. So, e.g. the top right pin on my hand drawn diagram is a red wire which connects to both the main fuse and the power source fuse socket. The other side of the power source fuse socket goes to the positive (+) screw terminal, as shown in the wiring diagram a few posts above.

Hopefully that clears it up? It's early. I need more coffee before I type this kind of stuff, LOL.
