Thread: 4bd1 glow plug current

From what I have been told by someone who went to the snow country some years ago the glow plugs were not needed even in the minus temps but like you I would hook them up just in case. Pretty sure they are 12v like everything else on the vehicle but it would be advisable to use a relay of at least 30Amps. Hope you have a good swag Steve

Thanks Brian.
I've done the trip the last couple of years with a single pole tent. First year I was a bit underprepared. Had a good sleeping bag and thermorest mattress, beanie, thermals - but got to the point where I couldn't put on any more clothes as I couldn't fit in the bag
Froze my butt of the whole night, but my daughter who usually feels the cold badly was warm as toast in her -10deg down bag with extra blankets.

Last year was fine. Camp stretcher, mattress on top, sleeping bag with doona on top. Had frost on the doona in the morning but was nice and warm.

This year will be the first decent run for the rooftop tent so will see how that goes. SWMBO isn't convinced

I'm 24v, my one starts fine but cranks slow at -8C. No glowplugs.

The only info I have on the plugs is PI-49 for HKT 11v plugs and PI-50 for HKT23v plugs. No current rating, but you might find one if you dig through the following part numbers.

HKT PI-49
NGK Y-904M
BOSCH GPI-010
Champion CH306
Isuzu 8-94175158-0
Volts 11.0
Type SQT

HKT PI-50
NGK Y-954M
BOSCH GPI-021
Isuzu 8-94135377-3
Volts 23.0
Type SQT

Mines just 12v so will be interesting to see how much it struggles. I'll definitely try without glowing for a start.
I should probably stop being lazy and just hook up an ammeter to one of the plugs - since I have'nt even got the bus bar across them at the moment so can get an individual reading.

I always thought glow plugs were rated in ohms? Once you have that number some basic maths will give you a fair idea, keep in mind you will be working out for parallel rather than series.

I'm not sure if it's the same for all glow plugs, but my 2A has a resistor in the circuit pre glow plugs.
I run the glow plugs on my log splitter engine (Nissan SD22) straight from the battery. I'm always worried that they'll burn out if there should be a resistor in the circuit.
The 2A takes a good 30 seconds of glow to fire when dead cold, the SD22 about 10 seconds.

my 110 started fine this morning in -6 without plugs.

..btw do the factory 110s have glow plugs as standard? is that the green light than comes on when you hold the key just before engaging the starter? (doing so certainly makes the volt meter lower)

Must vary between vehicles.
Just checked the wiring diagram, and Isuzu 110 doesn't have any resistor in the circuit, or even a relay for that matter.
Just straight off the ignition switch.

Flagg: Yes, there's is a glow plug light that's on when the plugs have power.
