There are 3 fuses you need to check. One is a 140A fuse at the battery, the other is a 100A fuse near it. The third one is a 10A that comes off terminal 3 of the alternator. Page CHG-14 of the FSM has the info. Do not rely on visual inspection, take a ohm meter and check resistance. All three should be under 1 ohm. My bet is on the 10A fuse for terminal 3 of the alternator.
