Prevent mysterious battery power loss

Even a slightly corroded battery terminal can shut down the power to your rig, and it usually happens at a critical moment.

Extra diligence at keeping your terminals clean will prevent untold electrical troubleshooting time trying to figure out whether you have a short circuit, blown fuse, or mice-chewed wiring.

Wire brush the connections often and spray on a thorough coating of battery terminal protection spray, which is available from any auto supply store. And when you have a mysterious power outage, check your battery terminals first.
