A turn signal relay (also known as a flasher relay) is an electronic device that controls your car's turn signal lights and makes a clicking sound when you activate them.

One of the most common problems with dual battery setups is the failure of the fuse/holder. Poor-quality fuse holders often don't make adequate contact with the fuse, which can allow dirt and dust to get in between the contact points. This causes excess heat to be generated due to the high resistance, which can melt your fuses and even melt your fuse holders. Even if your fuse holder doesn't melt, you could be losing valuable charge to heat dissipation. As a result, this could cause no charge to your auxiliary battery, but it's usually diagnosed as a blown fuse unless you're talking to experts like us!

A circuit breaker is an automatically operated electrical device designed to protect an electrical circuit from damage caused by overload or short circuit.

We offer a wide selection of circuit breaker kits, including manual and auto-reset models that are designed to fit the cable required for your application.
