hi, just been thinking about glow plug timers.
what excatly is there purpose, and, would there be any benafit to be gained from fitting to my B6000's and 7100's.

Glow Plug timers are just exactly that.....it allows the glow plugs to heat up for a set amt of time which could be longer than necessary especially after the machine has been running and doesn't need preheating of the glow plugs. Personally I would think it would be better to activate the glow plugs for the amt of time needed manually for different weather conditions(temps)

Recently replaced one that was hung 'on' and running down battery even while engine was running.

Don't know exactly how it knows but does vary the time 'on' based on engine block temp and ambient air temp. Or so I was told by tech.

My bet is--based on wiring harness and parts book--it reads only the engine temp and times itself accordingly.

In hot summer it clicks off in a second or two. Dead winter it might sit 'on' for fifteen seconds on coldest day.

My OEM replacement cost about $70.

If you don't have one as original, I'd be inclined to go with pushbutton and experience based on air temps. That's what the Army did / does on its heavy trucks---hold the button down until it feels right then engage starter. System works fine.
