    any kind of stereo equipment? If it's not shutting down that will do it
    Also if you have avolt meter hooked directly to the battery tha will do it to.

    The worst for a battery is if it is completely emptied. Thus it can
    be destroyed in a few weeks. Control first if the generator functioned. If yes, then test if a consumer draws unnoticed current from the battery. Best with an Ampèremeter. In addition, it can occur that a battery has a material defect.

    Also double check for exposed positive cable from your battery to the starter around the frame and your exhaust manifold. If its got a spot that the shield is rubbed off and it gets the slightest ground this will cause it to go dead everyday and a half. Just take a double look to rule that out.

    How many volts is the alternator putting out? Just because something is new doesn't mean its working right. Isolate problems BEFORE replacing everything under the sun.

    Yeah, I had a similar problem that turned out to be the wiring from the altenator and the battery. Make sure that is all good and also check any add-ons like stereo equipment or anything that draws power.

    Between 13,5 and 14,5V.
    A full charged Battery has 12,5V
