Our Zareba® 1 Amp Fuse is a replaceable 1 amp fuse for all fused 110-volt models. Comes 5 per pack.
A few things you should know when repairing a charger. Most chargers can hold a charge long after they have been unplugged or disconnected from the battery. You can be shocked by an unplugged charger. The consumer assumes all risk when repairing or utilizing a charger that has been “repaired” or modified. In addition, once the charger has been opened all warranties are null and void. In addition, and state of federal inspections and approvals (such as UL, CE) are terminated.
I have your Zareba 100, it has stopped working, I purchased a new storm protector and that didn't fix the issue. It has power and the light blinks, when testing voltage it shows 6000 at ground but nothing on the lead, is there an internal fuse that may have blown?

Hi, thank you for reaching out.
A storm protector is designed to help protect your fence energizer from lightning damage. However, it will not correct an issue if the energizer itself has already been affected.
To check whether your fence controller is working properly, please follow this test:
Turn the energizer off.
Disconnect both the hot and ground wires from the energizer.
Turn the energizer back on.
Using a fence tester, place the hooked end on the positive terminal.
Touch the ground terminal with the probe end.
A properly functioning Zareba 100 Miles unit should read approximately 8,000 volts or higher. If your reading is around 6,000 volts or lower, this indicates the energizer is not performing correctly and would need to be replaced.
Regarding your question about an internal fuse: None of our current models has a user-replaceable internal fuse.
