Hi Everyone,
I have a 2003 ford f 250 6.0 diesel super duty, I am from the east as far east as you can go, AC NJ any way, it has been in the 20`s already here, I want to plug in the heater and seen that the end of tne cord was burnt kind of bad, dose anyone know if that means the whole block heater is bad or can it just be the cord, I asked that cause I put a new plug on the end and still did not heat up, could it be the other end of the wire or do you think the whole thing is bad, I ask cause it is a big cost change, cord, $ 18.50 cord and heater $156.00 S/S don`t give me much to play with, Thanks for your time one and all, Thank You.
And when this happened to me, I received excellent advice here to look into the Marinco Mod...which has been improved upon by the NOCO Mod (the NOCO has a better rubber compound and remains snug in colder temps).
Hi Everyone,
I have a 2003 ford f 250 6.0 diesel super duty, I am from the east as far east as you can go, AC NJ any way, it has been in the 20`s already here, I want to plug in the heater and seen that the end of tne cord was burnt kind of bad, dose anyone know if that means the whole block heater is bad or can it just be the cord, I asked that cause I put a new plug on the end and still did not heat up,
Its very common for the cord end dangling loose to get corroded. That in turn creates a high resistance connection when you plug it in which makes the connection heat up. If the connection gets hot enough it will cook the plug and some of the close by cord.
Now you say you have replaced the plug end but still have no heater. Did you use a VOM to check the heater while you were replacing the plug? Put your meter on Ohms and you should see roughly 20 ohms across the two wires. Those cords do fail or it might just be unplugged at the block but the heater in the block can also fail. More troubleshooting definitely required.
OK, I did the OHMS test today, no movement at all, so I took the plug off I had replaced the old one with, still no movement, so can it still be just the cord that is bad, it sure was bad at the plug. or is the heater done, what do you think, do the heaters go bad, Thanks

Thats what we are all here for...helping each other out. Not a bother at all.
So if I understand correctly, you unplugged the old cord where it plugs into the heater housing?
There should be two brass prongs in the housing and these are where you would place the two leads from the meter (one lead on each one). The switch on the meter should be set to Ohms and the screen should provide a value (which should bounce around a little).
I am away from my trucks right now or I would snap some photos.
If its difficult to see the recessed brass prongs while in the uncomfortable position under the truck then just unplug the old cord. Plug in the new cord. Run it out to the side of your vehicle where you can sit upright and have better ligght to see.
The new cord should not have any breaks in it since its new and so then touch the leads from the meter on the two prongs that you would typically plug into the wall (not the ground prong).
The first couple posts are a good instruction for the 7.3 but the principles for testing are the same for your 6.0...after the first couple posts, the thread gets pretty long-winded. All you need should be in those first posts.
ArcticDriver, Thank you so much Sir, I feel 100% netter now, I did not think I had the right one, after your reply I am going in for the kill in the morning, Thank You So Much,
Have A Wonderful Happy Thanksgiving and Be Safe And Happy To All.
