FYI: the 1000 watt BH uses over 15 amps. A standard houshold timer is usually rated at 10 amps. Make sure you have one that'll handle the load. You don't want to wake up to the garage burning down.

I am glad that this thread provided some much needed comic relief! I do not know where my friends came up with this carp. They spend hours on end out Elk hunting up in the mountains. Perhaps they had way too much Crown the night before they tried to start thier truck. It is VERY possible.

I was going to say we should warn you we all have the much older IDI diesels they were installed from 1983 thru 1994.
They are the fathers (7.3 IDI), uncles (7.3 IDI turbo) and grandfathers (6.9 IDI) of your Power Stroke 1994 thru 1997 (DI) engine.

Same rules do apply in this instance though.

I'd guess they are thinking of the starting fluid problem, not a block heater. With starting fluid you can crack rings which will result in a diesel "needing a fix" to get started when cold.

Actually a 1000 Watt block heater draws less than 10 amps.

Ohm's law: V*A=W. 1000 Watts divided by 120V=8.3 amps. If the supply voltage is 110V, then the current draw is slightly over 9 amps.

Maybe we are being too hard on our PS owner friends.

It is possible (in theory) that using the block heater could confuse the engine controller on the newer trucks into a shortened glow plug cycle for a given ambient temperature or something...

I guess we can just tell them that our old trucks have "industrial strength software" that was developed by Mechanical Engineers.

but whether you use a block heater or not at a certain outside temp will not matter to the glow plug controller taking a memory, cause the timer on the controller is determined by the temp of the engine. so if it is plugged in for 6 years, it may only time for 10 seconds, cause the engine is warm. then if you don't plug it in that night, it will time for 65 seconds, cause the engine is -5º

OK, after a little reading...

The PS glow plugs are controlled by a module which takes battery voltage, oil temperature, and barometric preasure as inputs. The module is not adaptive, so yes there is no memory. One interesting thing is that some California models have individual wires from the module to each glow plug and can detect a bad plug. Now that would be nice to have on an IDI. If I had a lot more time on my hands, I'd whip something up for y'all real cheap.

I guess if you had bad glow plugs and used your block heater every night at home it would start fine until you went up into the mountains.

how can you check the block heater for proper functionality?

plug it in, and wait a while, then feel the block where the heater is.
or if it is real quiet where you are, you can hear it sizzling after about 20 minutes.

Ok, you're going to laugh at me.

Where is the block heater anyway? Mine works, but I've never looked at it to see where it was.

follow the wire??
i think it is on the passenger side of the block, in a freeze out plug hole.
can't really say for sure, i never looked for it, cause mine has always worked.

has anyone considered using a power inverter on their truck to run the block heater maybe with a timer so the batts don't get drained?

is that more laughter i hear in the background?

I could see doing that IF you had it running on its own separate battery. Something that is isolated from the rest of the truck(with a solenoid) when the truck is off, that way you don't run down your main batteries. A deep cycle would probably be best.

You could use a latching relay so when the truck is started you just push a button and the hater battery will charge, when you turn the key off the battery gets shut off from the rest of the truck.

You could use an auxiliary output from an aftermarket keyless entry/alarm/remote start to turn the heater on from inside your house. These outputs can usually be set to a timed mode.

You will also want to make sure your inverter can handle low voltage situations without letting out the magic smoke, it is expensive to put the back in.

never heard of a latching relay but have used battery isolators like on motorcoaches, it just distributes the charge to the batteries without them being linked together and no switches!
i like the remote idea too.
