Thanks Gryphon. That looks good.
Are you using a zip tie to hold up your ground block? I'm curious where you're getting your +12v lead from? Straight from the battery (fused of course) or off the big 55A "dog bone" fuse?
Noticed you're from Calgary. I grew up in Raymond, AB.
I've never been to Raymond, although I've been within a few miles of it many times on my way to/from either the Coutts or Del Bonita border crossings.
One end of my ground bus is supported by the wire (I think #8AWG) that grounds to the frame at the centre panel bolt. The other end is supported by the zip tie you see. I get my power from the bottom end of the dog bone fuse; you can see the thick red wire (I think #6AWG) behind the thinner red wire that powers my air horn's compressor. I haven't gone to the trouble of fusing that wire because it's short and unlikely to be cut or pinched to cause a short circuit, and I think it's protected by the 55A fuse anyway. I like only having one connection to each battery terminal. Although I don't have one, I like the idea of the power distribution boxes you can get that have a built-in relay to easily switch on/off power with a ignition-key-switched circuit, like MarkT's
PC-8. Or you could get really fancy by dropping $300 on one of
these.
