Diesel engines Fire warning

Diesel-engined T3/T25s are not immune to engne bay fires.

The main area that causes these (not uncommon) fires, is the electrical system engine bay junction box, n/s rear. This is the small black box attached to the engine bay firewall (!) in the left hand rear corner as you face the vehicle. Almost all the engine loom wiring goes into or exits this junction box, which contains a couple of round multi-connectors as well as the glow plug relay.

HarryMann: All a bit tight in there isn't it? In fact, due to the large currents used by the glow plug system and the tight space in that area with liots of wires close together this can be a bit of a fire hazard.

There's a 50~55 Amp fusible link in that box (for the glows) - first make sure it hasn't been replaced by a length of copper wire! If it's blown, GSF do them I believe.
