1986 ROW fuse in engine compartment

I have blown the one fuse in my engine compartment a few times. Once blown, the engine dies and will not start back up....but everything appears to have power. After replacing the fuse all is good.

When I got the truck there was a 30amp fuse in this location.

Does anyone know what this fuse is for and if it should actually be 30amp?

All fuses behind the bulk head and under the radio are fine.

5.7 v8 I'm pretty sure it is a headlight fuse....I remember flipping on my brights when it blew. I will check the headlight grounds tomorrow which is probably a good place to start.

1987's never had under bonnet fuses. The 300Tdi was the first to have this... they had 4 maxi-fuses (or was it the mega fuse... really big, like 1 1/4" wide) that covered the main electrical areas (lighting, alarm, AC) not sure if they did the starting system though, and certainly the brake/headlights wouldn't be interconnected with the starting system.

You sure it's not some aftermarket alarm?

5.7 ? Well it sounds like you have a custom built truck so this board will be of limited value for the non original bits. As Jamie points out Defenders didn't have fuses under hood until the 93 model year and then they are maxi fuses. The original headlight wiring sucks. The full amerage of the circuit goes through the contacts on the dimmer switch and they tend to burn up/short out leaving you without headlights @ the worst possible time. Many re-wire this to add a relay so that the dimmer stalk doesn't carry the load.
