Second fuse panel picture write up. (1 Viewer)

so awesome, where did you get the battery terminal? That looks like exactly what I need... going to do your fuse block too.

 

[REZARF]

As far as the terminal, just head down to your local car audio place. Ask to see what they have on hand. I bought mine locally, another good source is Ebay search car audio terminals.

Thanks! This is one of my next additions to the Troopy, so the write up has saved me tons of time thinking how/where to mount things!

Cool fuse block and nice work, I just did the same in my hilux but used the blade fuse type...
Blue sea products are great...

 

[tyama]

Very nice! How would you set it up if you were doing one where the gadgets are wired for ignition on only? I was thinking about electric fuel pump, carb etc... thanks, ty

If you are running a 12 block with fridge, gps, 2m radio etc. what amp breaker should you use??

Awesome write up!

If you are running a 12 block with fridge, GPS, 2m radio etc. what amp breaker should you use??

Contrary to popular belief, fuses and circuits breakers are NOT designed to protect the components connected to them. Their purpose is to protect the WIRE between the source and the load.

To calculate the size of the fuse or breaker you need to add up all the max loads the total circuit will use then calculate the wires size needed to carry that current, then add 20% to ensure a low voltage drop. So, if you have a fridge at 20 amps, a ham outfit a 7 amps and aux lighting at 15 amps you have a total of 42 amps +20% = 50.4 amps. You would need a wire ga of 8ga. To protect an 8 ga wire from melting and causing a fire you need to protect it with a 60 amp fuse or breaker. The 10 amps gives you current surge protection for items (like amps or lighting) that have a high initial surge current (inrush current) when turned on.

Great job. I gotta look into Blue sea products now. I too am very interested in the brand and source of the battery terminal that you used. Thanks.

I was just checking out the Blue Sea website and they mention two options for the glass fuse block with cover the 6 circuit with negative bus and 6 circuit without.
ST Glass Fuse Blocks - Blue Sea Systems
Which did you use and why? Obviously like many here I'm no electrical engineer and am learning from this write up. Again thanks for a great write up.

YOU HAVE INSPIRED ME!!

Spent the weekend cleaning up my wiring on the 3FE40, and followed your lead with a blue sea fuse box. I used the one with the ground buss built in, and it made life easy centralizing grounds from my dash accessories.

Well, after contemplating how many little do-dads were getting added to the 40 over the years, and considering there were 2 in-line cheap-o fuses to wire up a few things. I decided it was high time to install a second fuse panel and get all these installed and powered safely and effectively.

I wanted to keep the same glass style fuses so I looked around and really liked the Blue Sea 5015 fuse panel as it has all of the following:

*It retains the glass fuses.
*It is made for the marine environment.
*It has fancy little labels.
*All stainless hardware.
*Small size, fits nearly anywhere.
*Ground bus for grounding everything at once.
*It has little yellow levers for popping the fuse out.

Pic 1: Here is the birds nest of the wiring I started with.
Pic 2: Here is the fuse panels new home. Glove box made a perfect fit.
Pic 3: The panel itself.

Very first post.

Very first post.

My bad, should have re-read the thread before posting this one up. Thanks

 

[lucky 13]

i want to see a picture of that frig.

Very nice write up. I have been contemplating how to add some accessory power to my 76 FJ40 and now I know how. Does anyone have a source for extra cigerette lighter style elec. banks.

 

[lc69hunter]

Awesome writeup...

I have tended to keep abusing my old OEM fuse box with more and more. Guess it is time to change all that.

 

[Chris123]

Just finished the install of the panel and it works great. Thanks for the write up.

 

[greenfox]

I did the same thing last winter but with a bigger 12 circuit that run,s all my extra junk

 

[Slow Poke]

Digging through old threads for aux panels and found this gem! Nice right up Rezarf. For those that did this: Is the panel switched on with the ignition switch? How is that done? I don't want to accidentally drain my batteries if I can help it.

An oldie but goodie thread about secondary fuse boxes. This is on my list of things to do.
