Hi fellow Alfisti
So, I'm having a bit of a gremlin on the 156... last May I installed a new JVC head unit, things were smooth. In September, it just stopped working. Then I realized, the backup lights weren't working either. I changed the bulbs, but no go.
Then I realized
both the radio and the backup lights are on the same fuse, a 10A according to the owners manual. Which surprisingly, was a 20A... I'd never changed it before.
So, long story short, I end up with new bulbs, checked the fuse on the radio is functional, checked the harness is ah-okay, replaced the 10A fuse. Turn on the ignition... all works!
Then I switch to rear gear... and the 10A fuse blows.
Then I remove the backup light bulbs, and check that when I switch to rear gear, the fuse doesn't blow any longer. So I thought, the issue has to be in the trunk wiring harness...
And this morning, I turn on the ignition, switch to rear gear... and there goes the fuse again.
