See Figure 1. The motorcycle has the following three fuses to protect electrical systems.

Main fuse (1): A 40A fuse that protects all the circuits including those protected by the 15A Battery fuse. Failure of this fuse will cause the motorcycle to stop running. See a Harley-Davidson dealer.

P&A fuse (2): A 15A fuse that protects the circuits of any installed accessories.

Battery fuse (3): A 15A fuse that protects all the circuits. If the battery fuse fails while the engine is running, the engine will continue to run and critical circuits like the ABS brakes will continue to function. The failure of this fuse will trigger a diagnostic code. See a Harley-Davidson dealer.

All other electrical protection for the motorcycle is accomplished by the body control module (BCM). The BCM senses conditions for individual circuits, interrupts power as needed, and resets circuits. If replacing a fuse or cycling power to the motorcycle does not resolve the problem, see an authorized Harley-Davidson dealer for diagnostics and repair.
