Is anyone familiar with the 'fixed delay' type glow system?

[Eurasiaoverland]

I have a 1989 BJ60 sold in tropical SE Asian markets with the 3B and the 'fixed delay' type glow system, i.e. no Superglow. There is an additional 'GLOW' position on the starter switch (so OFF-ACC-ON-G-START) which triggers a fixed 5 or 8 second glow period, irrespective of coolant temperature. The glow controller is a small box which I assume is just a timer.

I have replaced the 3B with a direct injection 15B-T which has an intake heater rather than glow plugs. By all accounts, this grid heater is not needed in temperatures above freezing. To save the battery and alternator, I propose to deactivate or bypass the glow system, without changing anything in the wiring.

Question: If I simply unplug the glow controller, will this stop the starter switch from engaging the glow relay?

Please note: The system works perfectly and I have absolutely no intention to fit a Wilson switch whatsoever.

if its wired the same as an 80, then yes.

If your going to keep the grid installed and then leave it connected so that it runs every time you start it I doubt you'll burn it out. Just get slightly cleaner starts and less fuel and soot in your oil.

Thanks.

With the G position engaged on the starter switch, the timer starts and will continue powering the glow circuit for 8 seconds or whatever it is, even with the starter engaged. So it's an extra 50 to 100 A maybe draw on the battery/alternator if I do this, which I'm not keen on. Either that or I have to wait every time, which will become very annoying in the usual 30°C weather. I'm not worried about burning out the grid heater itself.

I may put a switch in the circuit to the glow controller, or an NO switch which closes when the outside temperature is less than 0°C.

I think a grid draws more then 4 glow plugs. Should be a way to wire it so that it doesn't draw while cranking, the small positive wire to the relay/solenoid could be from the "acc" circuit instead of the "on" circuit.

What you're describing here is a Wilsoff Switch.

I'll show myself out.

Had to chuckle at that
