    OK guys, after a few false starts here is the prototype box.

    This is ALL new and is plug-and-play, fully populated with fuses and relays - you can chuck your old one away.
    The black bit is CNC machined.
    The PCB is redesigned with a modern 5-layer board.
    You can use your existing plugs on your original wiring harness.

    All that I need to do now is test it in a Mondial and make the sticker for the top.

    To the questions of (1) when are production boxes available and (2) how much each the answers are (1) about one month for the first batch of five, and (2) I don't know exactly yet.

    Any questions?

    For which models/years of Mondial is this fuse box designed? Without close inspection, it looks like the one in my 88 3.2

    Thanks

    It is based on the QV box found in my 83, 84 & 85 Mondials. I don't know whether it will fit the later (or earlier) models. I'll post some images of the original lable from the original fusebox in a while.

    Excellent stuff! But don't throw away old ones as they can be repaired.

    What part number did you base it on? The newer the better as the new ones seem to work in old cars, but not the other way around.

    Quick - someone plug it in and test it! This is so desperately needed. It will also save me a lot of time :)

    Clive I belive this will work on any year Mondial the box I have in my 82 8 is from a T which was repaired once in 10 years. That fuse box looks nice and I want one.

    The layout appears to be the same as for the Mondial 3.2 (I checked it against the 1987 wiring diagram), with the only tow differences being the location of fuses 11 and 12 (in the LH bank for the 3.2 vs. the RH bank in the prototype), and slightly lower fuse ratings (16A vs. 20A, 8A vs. 10 A, 5A vs 7.5A).

    as a new mondial 3.2 owner, i'm learning as i go so bear with me. i realize that one of the big faults with this car is the fuse box and their tendency to heat warp and "burn up". is it just a matter of time before this happens to mine or is it something that would've happened already so i'm in the clear???

    Not all go bad, but most do. The fans and fuel pump tend to draw more current as they age. Consequently the connectors that plug into the fusebox get extra hot due to the extra current. The pins are soldered into a multilayer PC board that also does not cope well with the extra current nor the heat. Connectors melt and boards split and tracks burn up.

    The basic problem is that the electrics in most Ferraris are marginal, and the Mondial is one of the worst. It is an Italian car after all :)

    Having said all that - don't sweat it. If it breaks - fix it. There's a great group of people here who can help out. Chances are the box in your car has already been replaced at least once, and if you live in colder climates and/or rarely use the AC then that's one set of fans that run less frequently. Fuel pumps tend to have a finite life too, so if yours has been replaced at some stage it will be drawing less current than one that is original. I wouldn't go replacing fuel pumps just in case though. I have a Mondial t and I'm pretty sure my fusebox has not been replaced and it looks to me that the fuel pump is original too - 56000 miles - and I have no signs of any heat damage YET! It's only a matter of time...

    Actually My fuse box is running perfect right now even after a 2 -3 hour drive the relays are not hot at all, the fuel pump gets its power directly from a 12v source with a wired relay and same for the electric fan which happens to be a 16" spal on a aluminum radiator the fuse box relays only works as a switch.

    looks great to me, mine is holding hands with carbon (from burning) and solder (from my amatuer repairs!) let me know when ready!

    That's the way that many of them have been fixed, and it is a very valid fix that solves the problem permanently.

    I'm ready too. Mine has that black, charred look around several of the larger wired posts. As for cost, it seems incumbent to me that the price will drive the market, not the other way around. Price them at $22.47 and you'll sell all you can make to every Mondial owner on the planet(not that many, I know). Price them at $22,470 and I think you may have trouble moving them. :)

    Can you give us a possible range of price? or a general idea? I need to start saving up. <Edit> I forgot to say thanks, great work and much needed.

    Looks like a great replacement for our weak Mondial fuse boxes. I've installed an external fuse for my fuel pump which eliminated my intermittent stalling problem so a new fuse panel would be a nice replacement. Please keep me in mind when you get to the point of setting a price. Thanks

    We put the new box into a Mondial and everything worked although there was a bit of a hiccup. The test car's wiring had been jury-rigged to overcome problems with the original fusebox so the park/sidelights did not operate correctly. The wiring on the car is now going to be returned to the original configuration and the new 'box tried again. It took about 5 minutes to swap the boxes over. The owner of the car asked if we could make new male plugs to finish the fusebox off nicely, I'll look into this.

    This was one of the problems we had to overcome with the design of the new PCB, i.e., the current draw for those circuits.
