    You need to be more specific about your system and which relay your fuse is connected to... This is a unimount straight blade with relay controls for the headlights probably right? And the relay with the broken post is the main power relay to the motor? That fuse is probably feeding the headlight relays, the controller and possibly the marker lights or signals. It will be attatched to the large terminal which goes to the battery positive post. Not the other side that is the output and only has power when the relay is closed. What it feeds is irrelivent, if Western put it in the original harness it is there for a reason, just replace it.

    I had a look at the schematics for a few relay systems and there are none that have only one relay, several systems have two fuses. It may be that someone replaced the two smaller fuses with one larger one. If that is the case you need to put it back to original. Have a look at this manual in the section for relay systems and see if you can find your system.
    Page 82 shows a 12 pin system (two plugs at the grill) with relays and two fuses on the motor relay.
