The electrical system is protected by blade-type mini fuses and one 50 A slow-blow fuse. A blown fuse means there is an overload or a short somewhere in that circuit. Before replacing a blown fuse, find out why it blew and repair the cause.
| Interval | As required |
|---|---|
| Time | 10 minutes |
| Tools | Fuse puller |
| Parts | Fuse of the same capacity |
Identifying your fuse box
The fuse boxes are in the battery compartment beside the battery. BX tractors have been built with three fuse box layouts:
- Type A: one 12-fuse box at the low position, with some empty fuse positions.
- Type B: one 12-fuse box at the low position, with every position filled.
- Type C: two 8-fuse boxes at the high position, above the battery.
The slow-blow fuse is a separate plug-in fuse near the fuse box on all three types.
Replacing a fuse
- Stop the engine and remove the key.
- Type C only: pull out the pin and remove the accelerator cable to open fuse box 2.
- Find the fuse for the circuit that has stopped working using the tables below.
- Pull the fuse with the fuse puller and look at the metal strip through the clear body. A blown fuse has a broken strip.
- Push in a new fuse of the same capacity.
- Type C only: close the fuse box and install the accelerator cable with the pin.
- Turn the key on and check that the circuit works.

Slow-blow fuse
The 50 A slow-blow fuse protects the electrical system against a wrong battery connection. If it blows, check that the battery cables are on the correct terminals before installing a new one.
