[Rosqoe]

Battery light came on this morning on way to work checked battery pulled alt had it benched tested check the alt fuse under hood and noticed the fuse labeled as audio was blown replaced it fixed problem but it's randomly blowing the fuse could be fine with car running for an hour then blow or blow as soon as I put new fuse in
Any advice ? to

was it a stock mach amplified system? If so I would start by looking under the radio to see if the front amp is still in there. The mach amps are known to cause battery drains not so much blow fuses but The deck would be the next place I would look behind to see that there is no bare copper showing. Are there any accessories plugged into the cig lighter?

No radio in car it's labeled as audio in fuse diagrams but it says ignition switch lol

is the wire harness on the radio intact or has it been cut and grounding out?
