Q: Battery drain

asked by on

Will fuse's that light up when blowed drain the battery because the light on the fuse stays on,,,? Thanks

My car has 101765 miles.
My car has a manual transmission.

The smartglow fuses you are referencing won’t directly place a noticeable drain on the battery themselves, but if they are blowing repeatedly then there is an electrical short somewhere that could be causing a battery drain on another system. If you are experiencing a battery drain along with repeat blown fuses, then I would suggest having the car inspected for electrical issues and having the battery tested by a qualified professional, such as one from YourMechanic.
