fusebox circuit board advice

Not that I know of Ross …

Newman upgrade prevents boards from blowing , do that imo

 

Fwiw the fuel relays were removed from the original board and located remotely on my fuse panel, work done by previous owner’s service shop.

Well, during my recent major we uncovered there was a reason why my car was having issues. My fuel pumps (original) were in terrible condition, drawing a large amount of current, and in need of replacement.

Everyone is so quick to replace their fuse board, and I understand why and will eventually do it as well (albeit with the GT Carparts board). But its worth evaluating the condition of the primary problematic excessive current drawers: fuel pumps, radiator fans, etc. In reality these parts may be the root cause of certain issues that a new fuse board will simply cover up.

 

lots of ferraris in Florida and Texas, they wont melt; although as you know the AC on the older cars.....

 

Keep the A/C R-12 if you can!

 

Worth trying Dave Helms at SRI

I had my 512TR & F40 done a while back through him and are very good. The mods are non-OEM but can be neatly hidden behind the board itself. I know there were some issues with RHD 512TRs but he may have long solved those by now.

 

I actually pulled the Dave Helms unit out of mine and replaced it with the GT Parts board. (No affiliation). See the recent thread ‘83958 Major - 2016 - Fuse Board’ for more.

 

I would personally add 3M crystalline to your windows

As for the BBi, I would replace the factory fuse blocks with the Birdman blocks. Yes you'll lose authenticity, but the BM blocks work great and offer a lot of advantages. And, they're easy to install.

I don't own a TR but from what I understand, there are high load items on the printed fuse/circuit boards. These items use the thin strip copper on the board to carry the load and they're just not up to the job. This from a guy I met with 180K on his TR and who does all of his own maintenance.

If there's a better board, and I'm sure there is, I'd replace that as a precaution.

As to tf308 and the 3M Crystalline, he couldn't be more spot on. The windshields in the BB and TR are huge and allow for a tremendous heat load in the car.

I did both my 308 and BBi with Crystalline and it made a HUGE difference. I can actually drive around on a 90 degree humid Florida day and be comfortable in them both. Plus the 3M isn't dark and it's almost clear. At least mine is.
