Default Fuse Box Design

Hi all;

After days of scouring the forum for tips/guides, I came up with this design it's a modified design by Pocket, his postings helped a lot!

What do you guys think? Comments remarks any changes?

I have some questions myself...
Are the fuses/circuit breakers ok?

Would you add 5A fuses to the switch side of the relays?

Regarding the Ignition relay, a regular 40amp relay is fine here? All the IGN circuit go through it so would this not be too weak? My electrical knowledge is very basic.

Thanks!

That's a lot to hang off one 40A relay.

I would split the powertrain related circuits onto their own relay then divvy up the others according to load. It's more work up front but the more independent the loads are are the easier troubleshooting is in the future.

You need a diode on that high beam out to the dash lights, or when you turn on the low beams the highs will also come on. Because of the path to the guage lights.

You would also need a diode on the lows in the same place if you don't want the lows to come on when the highs are on, but you may want that, and if so, then leave it out.

looks good, but I would draw in a (obvious to us) ground from the battery,

What made you deside to invest the time it takes to draw up something like this?

True on the grounds Will be grounding the battery to chassis and engine block to chassis too just did not want to clutter the diagram with ground lines.

Haha lot of time is correct. I thought if I ever need to troubleshoot I would not remember what I did.

Also maybe someone on the forum could benefit from this.

Thanks again for the diode tip!

Cheers.
