Ferrari 308 fusebox problems

Main auxiliary fuse (indicators, etc.) #1 melted after a run out! Not the conductor but the plastic part of the fuse due to excessive heat across it caused by resistance at the terminals.

Researched this on http://www.ferrarichat.com/ and it is a very common problem with the fuse box. Especially on the high current / always on applications such as aux systems, fuel pump! radiator fans. The fuse holders are riveted onto the spade terminals and the physical connection through the rivit deteriates. This encourages corrosion which in term increases resistance to cause a downward spiral of your 308 electrical system

Ordered myself a pair of famous Birdman fuse blocks with the glass type fuses and non riveted connections which took a few days to arrive and about 30 minutes to fit. Never seen an electrical gremlin since!

Also repaired O/S heater duct flap which stopped working, inner cable stiff. Dash removal easy, but access to cable and clamps difficult.
