In my last thread I was working on some electrical problems with my charging system. While I was sorting that mess out (and still am to a degree) I found several other wiring issues that were not in the main charging system but still need to be fixed.
Most issues I have are where a PO added stuff onto the wiring harness. There are exposed wires, excessive use of crimp connectors, and in my opinion poor choices in where to tap into 12v power, and in addition a lot of long runs of hot unmarked wires running around places they don't need to be.
I want to run this by you all and see if I have a good plan. Suggestions and recommendations are very much welcomed.
1. Use a relay switched on by key on ACC. (Hot with Acc and Run, but not start correct?) This relay will switch power from a wire to 12v hot from the start relay post.
2. Relay activates a fuse panel. I'm looking at a Bussmann that uses 1 hot wire in and has 6 out connectors that are fused by ATC blade type fuses. (I might need more later on? See later part of post.)
Here is the fuse block I'm looking at, it's on the right side of the page. I can get a 6 port at NAPA for $20: 15600 Fuse Panels - ATC Footprint
3. Connect my accessories.
4. For my electric radiator fan, add a relay (possibly delayed? So it won't run until I have time to get the engine running.) to that hot wire switched by a key on (RUN) hot interrupted by a manual switch in the cab. This would allow me to turn the fan off when not needed. (Probably a future topic when I go over my cooling system.)
Here is my current list of accessories I need to hook up or plan to hook up.
Electric radiator fan
Electric choke
Planned CB radio
Planned in cab 12v power point of some kind, possibly a 2-3 power point strip run off same wire.
Possible lighting?
That is 5 accessories right there for a 6 port block. I suppose I could combine some in cab accessories to one hot wire coming in, say my 12v ports and CB together. (Might add additional inline fuses, which I was hoping to avoid.)
Would I be better off with an 8 post, more? Or would I be good with 6, and not worry about it until I fill that up, if ever. Also, how much can you safely run off one of these and will the wires be adequate. I'm thinking about 10-12 ga on most of this stuff.
And lastly, any photos or just descriptions of how some of you set up your accessory wiring would be great to give me ideas.
