alfa romeo 2600 spider fuse box: proper fuses

[benicia 2600]

Hi
Looking at my owner's manual and at the parts books I was not able to determinate what the proper fuse arrangement should be. i noticed that 11x 8 amps fuses and 3 x25 fuses were used(in spite of only twelve slots).
Does anyone have some information or pictures of the proper arrangement for a spider?
let me know

Herve on page 138 of the OM it states that all fuses are rated at 8amps with 2 fuses as spares

Hi Michael
In the parts book it list about , 8 amps 25 Amp and 15amp.
In some alfa nots on my owners manual it mention that fuse 5 for the fog lights should be 15amps.
I have not much infos on this subject.. does any else has more specifics?
regards
Herve

Ruedi and Herve, As always thanks for your insight. I agree about the foglights,my car came with foglights and the "extra"switch on the dash before the previous owner modified them . The wiring is larger and would lend itself to a 16 amp fuse. I am in the middle of installing a seperate relay for the headlights,not just for brighter lights but just to protect the 50 year old wiring and switch. My car is back for the upholstery shop and Ii will be posting some photos of the interior next week.

My car has been safely re-wired as you suggest . The dim /dip switch on the steering column is used to switch a low volt relay - this then feeds high or low beam - better than feeding the full headlight current through the switch

I may be a heretic here but electricity is one area where I think originality should be sacrificed for safety. You can keep the orignal fuse block and 8 amp fuses, but convert the hi-amperage circuits to relays with separate supply feed from the battery feed or alternator terminal.

To be safe, the wiring should be re-done from headlight/foglight all the way back to the relays in addition to new feed wires.

One of the best benefits from new circuits is that they will take a load off the column and dash switches, thus preserving their life. They also will allow you to match wire size to loads and fuses. Use a heavy gauge (14) for the supply feed; 16 should be fine for the leads from relays to lights. Relays and in-line fuse components are available at most auto stores.

Here's a pic of a little relay panel with circuits for high & low beam and fog light...it's mounted on the existing panel where the horn relay is. To keep things looking more "original" you could of course use just black wire, but then it might be a good idea to use labels on the wires to identify them in case you ever needed to go back and trouble shoot.

Note also the shrink tubing to insulate each wire spade just in case anything vibrates loose. The fuses are not shown- they're "in-line"- spliced with quick connectors.
