What is the fuse Number for block heater of an 05 Ford F-350 diesel?

There isn't a single fuse number for a block heater in a 2005 Ford F-350 diesel. The block heater is typically wired directly to a dedicated circuit and does not use a standard fuse in the fuse box. Instead, it's protected by a circuit breaker or an in-line fuse located near the heater itself, often near the engine block or in the wiring harness leading to it.

To find it:

1. Consult your owner's manual: This is the best place to start. It should have a wiring diagram showing the block heater circuit and the location of any protective devices.

2. Inspect the wiring: Trace the wiring harness from the block heater itself. Look for an in-line fuse or a circuit breaker near the engine. These are often cylindrical and may have a visible number or rating stamped on them.

3. Check near the battery: Sometimes, the protection device is located near the battery, but this is less common than being near the heater itself.

If you can't find it yourself, a Ford dealership service technician will be able to locate and identify the protective device for your block heater.
