Fuse the Charge Lead

Most OEM charge leads have a fusible link on them. Its purpose is to protect on-board electronics in the event that the regulator fails and causes “voltage run-away.” Although this is quite uncommon, fusing the charge lead included in any of our kits can provide the same protection for your larger than stock alternator.

When choosing this option, we’ll include a Rockford Fosgate ANL Fuse Holder, a 100A, 150A, 175A, 200A, 225A, 250A, 300A, 350A*, or 400A* fuse (your choice), and mounting hardware. In addition, we increase the length of the charge lead by 1 foot to allow you to choose a good mounting location for the fuse holder and still have a nice smooth run from the alternator to the battery.

*Recommended for 2/0 AWG Big 3 Upgrade Kits ONLY!
