Fuse box upgrade (prototype)

[Bmachine]

Thank you for the images! That is very helpful
What I am looking for are the connections between fuses. I circled an example shown in one of your images (a connection between #3 and 4):

There should be one between 5&6 right under your finger in the image above and also 9&10

Gotcha. Isn't that indicated on your schematic above? For example 3 and 4 are connected on the schematic. But, I will definitely look for a photo that illustrates that better

You are correct, they are indicated in the schematic and that is what I wanted to confirm.
I looked more closely on some of the pics above and i think i spotted the linkage between 5&6. So the schematic for the post 1973 seems to be correct.
I already ordered the PCBs. I should get them in a week or so.
Now I am more convinced of the importance of adding the LED indicator.
I will work on that for the next revision.

You can trust the schematic.

Again, crappy photos taken from a video for the reasons explained above. But if the color coding on the PC is any indication, it confirms that 3 and 4 as well as 5 and 6 are bridged

First attempt at fuse indicator:

Nice work!

 

[Ezz]

In vehicle LED indicator test.
Since this is confirmed, i will be ordering the revised PCBs with LED indicator circuit.
The next prototype should be ready to install with in two weeks.

This is getting very close to final prototype. Actually this next order will be the final PCB revision unless of course issues comes that will need to be addressed.

I would like to know if there is interest from members to use my fuse box design in their cars…

 

[Bmachine]

I would be interested!

Interested in '74+ version

 

[merdad]

Of course interested for 2800cs

Hi Ezz-- this is my '71 Ep fuse box - and I woudl be very interested in testing your upgrade

 

[Markos]

Not sure if it helps but I made this:

Not sure if it helps but I made this:

thank you, this confirms that the early E9 is exactly the same as the early E3 with 10 fuses.

I am interested!

 

[Ezz]

Sorry, I have not posted an update in a while. I have been busy with the E3 (almost ready to crank the engine!)
I found some design improvements to the fuse box that I am working on currently before I can order the PCBs. I will share the details later.
