Blown fuse Archives - Transmission Digest
Technician Turned Sleuth

How often have you accepted a repair knowing that others have been involved? How often are you required to channel your inner Sherlock Holmes? Two recent repair jobs led me to unusual conclusions.

One of my customers brought in a Nissan Sentra that had a habit of blowing its interior-lamp fuse. She would replace the fuse, and then it could fail within hours, or it could take days before it popped.

Most of the time when I see blown fuses, there is a direct connection to either rubbed factory harnesses that aren’t routed with enough free play – sometimes accompanied by a TSB – or it is due to the intervention of human hands during a repair or modification, such as an aftermarket installation.
