We’ve integrated an ANL Style Fuse Holder into the charge lead. It includes a 150 Amp ANL Style Fuse. 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.” Fusing the charge lead provides the same protection for your larger than stock alternator.
