Barreling down the interstate after many electrical gremlin free years, and noticed my instrument cluster dead. Quickly isolated the issue to fuse number 12, swapped at a rest stop and continued along my way without incident.

A few years ago I installed all new ceramic fuses. I think the only thing I’ve ever blown was the classic number eight fuse before cleaning and lubing my blower motor.

This one’s a little odd as it’s such a low draw fuse. The only thing I can think of is my cruise control causing a surge…?

Do these fuses have a service interval that might explain this? Or does current just happen sometimes? I generally tend toward issue in need of resolution.
