Main fuse box hot. 1.6 NA

Postby ozi_milhouse » Mon Feb 05, 2018 5:12 pm

Hey all,

Recently noticed that after a reasonable drive with lights on, internal hvac fan on and a running engine cooling fan, the fuse box main bus bar gets hot, to the tune of 60 degrees c. Now to be fair I don’t know if this is normal or not but I would expect not.

Yes I’m pulling loads of current with all those items on, but I upped the cable from the alternator to the fuse box to a 4 gauge batter cable (thinking the alternator cable had perished) and that helped to drop the temps from 70c down to 60c after a 30min drive in the heat of the day.

Can someone do me a solid and check the temp of the main fuse box lead in cable from the alternator after a long drive and let me know if it’s hot?

Cheers

Justin

Check the two main terminals in the fuse box. Someone posted photos of these discoloured and I had the fuse box catching fire on the formation lap at QR.
