The 20mm 1 AMP Fuse pack is great to have on hand in case you get a blown fuse through your controller. A Blow fuse is a result of an electrical overload. This could be a result from a system fault or a power surge. A common fault is a solenoid coil rusting and shorting out. To identify the problem coil, observe the controller and watch what station blows the fuse.

Before installing a new fuse, ensure that any electrical problems have been addressed & fixed otherwise the replacement fuse will blow also.

NOTE: Replace blown fuse with the same compatible size.
