60 Amp glow plug fuse
I've been having some engine problems and have read some fault codes. Amongst others I was getting P037D-29 Glow plug relay sense circuit and was unable to clear the fault code (engine was starting fine).

After a bit of seraching I found that this 60 amp fuse is to do with the glow plug and was missing on mine.

Ive installed another fuse and now the fault is gone, however the main cable from the fuse does get warm (but can be held in the hand no problem) I'm wondering if there could be a reason why this fuse has been removed in the first place any sugesstions appreciated.

Have you got a shorted out glow plug or broken one? They can be a swine and snap off in the engine bay, the other common one is the wire at the front of the engine the supplies power down to them wire nut thing fails.

Is it warm all the time or just during the glow cycle at startup? It is controlled by a timer and relay so even if there is an issue with the circuit it should be switched off after the startup glow cycle > 110 XS Double Cab

thanks for the help. I sorted my main problem out with the injectors and I've removed the fuse as it does not seem to make any difference to anything.
