Now I'm a liar

[CUCVFAN]

What about the last GP on the right side of a 6.5 TD, I can't even see it let alone change it. I have not changed it and my truck still starts well with the other seven SS plugs. Will that loner eventually give me problems that will force me to find it?

No, this is a CUCV only problem caused by the firewall resistor in series with the glowplugs. If that plug goes bad, it will just be a little harder to start in the cold, but probably not very noticeable. Civvy trucks pull directly from the batteries (12V parallel) and therefore cannot see an increase in the voltage like this.

 

[CUCVFAN]

so I need to put 8 new glow plugs in and then test the voltage?

Yeah, but you must test it loaded and don't test it for long. Or, just hook them to the 12V junction and don't worry unless you are stone dead and need a slave start.

that is what I was thinking of. unhook the 24v line from the resistors and tape off. then run a 12v line from the battery.


Do I need any type of fuse?


should I run it from the 12v block on the fire wall?

 

[CUCVFAN]

That's where most people move it to. No fuse needed. The wire is almost the perfect length as it is. Remove it from the resistor and move it to the junction. The plugs are not in use very long or when you are using lots of accessories, so you should not overload the wire. To be safe, just make sure you don't try to start the truck with the headlights on, wipers on and heater fan on high.

Ok, Napa had the 60g plugs for $10.49. I'm going to install them, change my wire and see what happens.

I will report back.

It will be nice to have my pickup back!!

i hit the tabs with the belt sander so they'ed fit the stock connectors...personal preference i guess.

If you want to replace those resistors, I have the ones from my CUCV that I pulled out when I changed the starter. I can send em to ya.

 

[OPCOM]

with all this issue over burned resistors, seems like someone would have figured out the resistance and used a resistor 4 or 5 times larger in wattage than necessary..

 

[rizzo]

I installed AC 60g plugs today and tested the voltage from the resistor. it was 24 until I jumped the relay then dropped down to 11 ish. the truck started right away. I am still going to run a second wire to twelve volt.

I don't think this guy knows what he is talking about



Hi,

Resistors are tested under NO load. Thats basic electricity 101. I have a BS degree in electrical engineering from my previous career.

I had advised if you send them back, and I will investigate this, as we've never sold any other brand then Wellman. I cannot promise warranty, but I will see what I can do. And please read our warranty policy page on the website. It states "limited warranty" not "unconditional" warranty. But you saying they are a different brand just makes no sense. But I am willing to look at them and discuss this with Wellman.


Thanks,

I'm not sure what his point is? You do test the resistance of a substance under no load with an ohm meter, but your last under load test seems to indicate the resistor is fine.

 

[OPCOM]

well.. he does have a "BS" degree.. Resistors can be tested in or out of the circuit and with no load (ohm-meter) or with load (measuring voltage drop across resistor and current through resistor, etc ) If the voltage drops friom 24 to 12, then the resistor would seem to be in order.

I assume this is a regular resistor and not some temperature or voltage dependent variant. If you have an ohm-meter, preferrably a digital one, why not disconnect the resistor and measure its resistance? That would be of interest. There's a large old-school surplus electronics store near me, I could check for high-wattage substitutes that would likely never ever burn out, short, or do other un-resistorly things. It would be worth it to save controllers in the long run, no?

I assume this is a regular resistor and not some temperature or voltage dependent variant.

Actually I am pretty sure they are one of the latter 2. I am pretty sure thats part of the controller function.

 

[CUCVFAN]

It's a standard, wire wound resistor. The resistance should be 0.28 ohms +/- 5%. Any normal variation of temperature would not affect the resistance.
