The fuse boxes on my 84 308 gt

The fuse boxes on my 84 308 gts are starting to give me the fuel pump and fan switch problems. What would be the best way to "cure" these problems. I am leaning towards putting in an aftermarket fuse box with new style fuses. JRV what would you recommend to do?

Ferrari UK sells the fuse bloc

Ferrari UK sells the fuse blocks fairly cheap, something like $60 (dollars not pounds). And with them lasting on the order of 20 yrs, to modify to some new type box doesn't seem cost effective yet, if you're paying a mechanic, compared to the ease of just switching them out with new.

There's certianly nothing wrong with modifying them if you can find an actual upgraded part and relabel them so there's no confusion down the road if electrical gremlins pop up.

If you decide to stay original box, Buss makes glass bullet fuses that fit in the original holders and someone is making gold bullet fuses because it's long been suspected that the metal used on the ceramic fuses was a big part of the resistance problem due to corrosion of the metal used.

Two months ago, I fabricated a new fusebox from a two NAPA fuseblock (say, $7 a piece), some aluminum and some rivets. I used standard glass fuses, as well.

The whole thing was like $40...

Simply suggesting here that there are other options than buying two new fuse blocks that will eventually develop the same problem.

Mike,

you did a great job on your fuse box replacement.

you must remember though, not everyone can just go into the garage and fab up replacement Ferrari parts of a higher quality than came from the factory. In the case of the fuse blocks, since they seem to last 15-20 yrs even though they aren't the best design, in some cases it's easier just to spend the money and move on. Of course if a guy is really handy like yourself then making improvements is the way to go.

Best Regards, JRV

JRV,

Agree very much that it does makes good sense to just get new OEM blocks that will last for another 20 years. Combined with the GBC "Buss" brand glass fuses you mention above (which I bought, but returned), my feeling is that would be fine.

By the way, I had a heck of a time locating the right glass fuses. I ended up getting the bullet-type, Bussman GBC glass fuses online here:

http://doitbest.com/shop/product.asp?mscssid=EPLEWRK47Q218JBVCVJEXACAC1UVCJ1D&mbrid=4724&dept%5Fid=4663&sku=570710

This place had excellent service (even though I had to return them, since my custom-made box uses AGC type fuses).

SKU 570656, glass tube fuse assortment. You want the GBC ones for "german" cars, #KG-5.

These are the fuses that fit inside the OEM boxes. Would be very interested to hear about the gold ones...

--Mike

Hey Mike,

these guys look like they have Gold Fuses as part of their regular inventory:

and these guys:

http://www.metro-auto.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=010&Category_Code=104-19

Gold fuses are used in stereo applications because they can stand constant amp draws across the circuit without corroding unlike brass and copper which oxidize when heated..

I used a google search, so there may be other or better sources out there.

HTH's

Mike I used your idea and did

Mike I used your idea and did the conversion. Works sweet. When I removed the 2nd OEM fuse block it broke up in my hands. Also if you use i piece of 1" wide alum. and mounted it to the 4 stock mount holes you can keep the NAPA fuse holders connected. Also I soldered a "buss bar" to connect the comon lines. Thanks
