83958 Major - 2016 - Fuse Board

Or does it? There’s plenty of probably cause suggesting the burnt up connectors are due to board delamination issues.

Dont forget a user just posted on this thread that he had to switch out the the Helms modified OEM board before some electrical gremlins went away.

 

What you see is the Plastic vernis layer I put on every board to protect for external influences and moisture. So no overheated connections.Yes sometimes the plastic wire protection is to shrink a little bit close to the solder points, that is unavoidable. Solder temperature is 285 °C (I use high melt temperature solder) and plastic melts at 70 °C or less.
You can even wash my motherboards in water with detergent if needed and dry it with a hair dryer or leave it in the sun. There are 97 boards installed for the moment and a waiting list of 10 that will be delivered after my return in may.

Because the delamination occurs where the connector is soldered to the board.

 

I can’t speak to that level of specificity because all diagnosis and replacement work was performed by a Ferrari tech who described things in layman’s terms. As such, I also can’t speak with precision as to what degree the DH/SR board caused problems. What I can say with certainty is that as soon as that board was taken out and the GT board put in, all of the following issues immediately went away: starting problems, fuel pump shutting off, battery dash light flickering, headlamps working intermittently, and door lights not working at all. For what it’s worth...wish I could be more helpful on this topic.

 

Thanks Vincenzo....after soldering about 200 solder point at more then 100 boards (97 + 10 in stock), yes my skills are improving.
And saying it all started with only 1 board, for my own car...because DH kits did not satisfy my expectations and $$$$ for a few wires and relais, GT parts also $$$$, Zertec did not get it sorted out with his boards and there where no others on the market with a solution. Then a friend wanted one for his car, then an other and so on...and it is still a hobby for me. Counting the man hours I cannot otherwise my boards are much to $$$$.
So I'm happy to help many others to keep their car on the road. Even 3 X F40's are provided with my boards (same price for a board like all the others ! No extra F-taxes).

The DH/SR board was installed by the prior owner, and I don’t know what issues prompted the change.

I don’t have the old OEM board.

 

Connector looks fine to me. Suggests an issue between the board and other end of connector whose heat travels out and burns the plastic connector housing. What do you think?

 

Manipulating fuses, relais and the wire plugs, makes the single solder points break slowly....lesser contact, more resistance so more heat building. The use of WD40 and other sprays are helping delamination of plastic layers. Its a mix of conditions that fuseboards are melting down.

We’re on the same page. The only thing I would add is this: the original board has already received numerous heat cycles and the effects of time/oxidation, plus being made from older materials/methods. Removing high current circuits is a good thing, but the board is still old.

The original board has lasted dozens of years and thousands of miles with those high-current items run through it. Because od this, if I was going to replace anything first, it would be the old board. It worked well enough for a long time and the newer board should only work better. Just seems to make the most sense.

 

is the original then still available?
the ricambiamerica side says: no

 

What type of concerns were u experiencing

 

The TR fuse box is a very well known issue. The board its self is crap-o-la. They do split and separate causing all kinds of issues other then in the high draw circuits. The GT board is a good unit regardless. It eliminates the separation issues.

That said. The burned connections are a result of high current draw. Sometimes related to the connections, other times directly relating to the parts drawing the current. The cooling fans, fuel pumps, starter circuit etc are all high draw items. As these parts get older, they will pull more amps and as a result create more draw which makes heat.

Check the components on the circuit. If they are drawing excessive amps, then all you have installed is a band aid. Fix the problem. Dont just address the symptoms.

 

Not only TR boards...all boards of that kind : All mondials, 328, 400i, 412, F40, 288GTO, TR, testarossa, 512TR old model board, and recently starting to melt down the models 456, 550 and 512TR new model board. Luckely I have the internal diagrams for all those boards.
Guido

 

Thanks to Joe from the US FYI I managed to get the new style 512 TR internal Fuseboard diagram. Here is a copy of this diagram ( this is the backside and split in 2 for more clearness). As from now on I will produce this board for who is in the need for one.

Do you still make these boards? I need one for a 1993 512tr

 

I started a cio

I started a conversation....upper right corner, click on your name...

 

Hi Guido @theunissenguido, how do the old and new 512TR boards differ? How do you know which you need? I wasn't aware that GTCP at least made more than one version, or that you did either until this thread just popped up (have read numerous other threads on this subject).. haven't really looked into SR/DH option. I have a 1994 Swiss model 512TR, #97504 which is having some electrical gremlins and I am hoping soon to find a little time to take a close look at the fuse board and go from there.

 

To my knowledge all 512TR have the same boards. Testarossa and TR have a different board....
This is how a TR/Testarossa board is looking ...white plugs on the left side are vertical and you have 2 lines (of 4 white plugs) horizontal lines lower side



And this is how a model 512TR board is looking (I think picture is from a 456...but its the same layout)
The colored plugs left side and lower side are all horizontal...

Best thing when you are looking for an other board is making a picture and send it to the seller.
