Chevy Truck: No 4x4 Needs Transfer Case Split!? What?

In this video I bring you along as I have a look at a guys 2002 Chevy 2500 4x4 6.0 that has a customer complaint of no 4x4. He had it at another shop and after they unloaded their parts cannon they decided it needed the transfer case split. It was at that point he thought he'd give SMA a try. Here we go. Enjoy!

My old man was similar. I learned how to rebuild a carb at a young age because my dad's sausage fingers couldn't hold the jets. Learned that and many others things due to being only 10 ish and having small enough hands and arms to get into those tight spaces. Lastly I learned how to correctly cut off the extra from a zip tie so that you don't create a future scalpel in the engine compartment. That's a handy piece of information right there.

He had just replaced the plug wires and spark plugs. I look down the side of the engine and one of the spark plug wires is almost in 2 pieces. I can see the spark jumping across the gap. The wire had melted almost all the way through and it was amazing that it was still running like that. He was embarrassed because he thought it was primary ignition. "There's your problem, Lady!"

[@stephensaines7100]

With solid state test meters (in almost all cases) even the continuity test, let alone the resistance ranges, is *polarized*! If you just have a circuit being tested that is resistive in value, it doesn't matter (with rare exceptions, caps and other components can throw that off) but if there are semiconductors (diodes, control modules, solid state relays, LED lights, etc) in the circuit, you might see a short tested one way, and an open circuit the other, and everything in-between. When in doubt, flip your leads around. I'm an electronic tech, and the more expensive meters are self polarizing for voltage checks, but when testing continuity/resistance, habit alone says to flip the leads if a reading is odd. You're absolutely right to query what your meter is telling you until you've addressed a number of quirks. I note the drive motor had a 'clamp' across it, two diodes in series, one shown in the schematic as a straight diode, and the other as a zener. Again, especially if the clamping voltage is exceeded by a tester (rare, dependent on a couple of factors) you'll get a puzzling reading. However, if the zener is shorted, and the motor is open, you'll be reading the forward resistance of the regular diode one way, and an open circuit the other. Your using an incandescent bulb addresses many of those false indications. Sometimes simple tells the best truth. Btw: Your logic is superlative. I've complimented you a few times over the years. Electrical logic can be hard for many mechanics, even really good ones, but for some like yourself, it comes naturally.

[@TheOmegaman69]

Eric, you probably have already found this, or already know this, but from the Power Probe IV manual - "LED, Green (-) - Will light indicating a path to ground. More than10Ω resistance and/ or more than 0.5 volts on a ground circuit, the Green LED will not illuminate. Additionally, from the Power Probe IV manual - "This greatly simplifies testing as the Power Probe IV’s Red/Green LEDs and speaker tones provide a quick indication if there are excessive voltage drops or circuit resistance. If the LEDs do not illuminate and there is no tone from the speaker, you know instantly there may be a circuit problem." In short, the Power Probe IV gave exactly what it should have, indicating a circuit problem because the Green LED did not light and the Buzzer did not sound. It indicated the solenoid is open, as it was. On the new solenoid the Power Probe IV gave the correct resistance. Great video, as usual though. Your videos are greatly appreciated and we thank you. They are also the best on KZbin, bar none. You are the best mechanic, diagnostician I have had any kind of experience with in 50 years, especially with electrical stuff, which I have found is most every mechanics weakest skill.

[@willardwilliamson6778]

The problem was that Mr. O checked the path to ground through the control board and even though the control board was indeed providing a ground the power probe did not indicate a valid ground. This is most likely the result of resistance in the ground path through the control board.

[@255Vicks]

Just an fyi from an electronics guy, solid-state components such as transistors and solid-state relays will mess with a multi-meter's ability to read resistance and continuity. Voltage and power measurements (as you did with the test light) are the only way to go. I enjoy your channels as well as Ray's as you guys go through the entire diagnostic process.

[@JosephArata]

Power probe isn't a real multimeter and no, you're wrong, a high impedance multimeter and/or oscilloscope are the ONLY way to properly test a solid state circuit.

[@lustfulvengance]

If it's pulse with modulating that circuit that's probably what screwed with his Power probe! I'm pretty sure you could actually hear it doing exactly that when he was shifting it and he was underneath the truck it sounded like a solenoid buzzing almost like you'd hear if it was on AC mains voltage but only while it was shifting.....

[@255Vicks]

Osxilloscopes read voltage vs time, not resistance and yes, semiconductor components will effect the ability of a meter to properly read resistance. The only semicondutor component a meter can test is a diode, and that is in continuity mode and with the probes in the correct polarity. Ij the case of a sinking circuit, that is, on that is switched to ground, a resistance or continuity check will not work if it is using a solid-state relay to do the switching. Don,t believe me, buy an SSR, and read the resistance across it in both the open and closed states

[@NBSV1]

@@JosephArata Solid state components usually have some leakage and don’t fully switch off. A multimeter is such high resistance it doesn’t pull enough current for the leakage to disappear. So, it can get funky readings that aren’t true. The power probe is a simple multimeter made for 12v. The one he has can do more than the standard one that basically just shows voltage along with supplying power or ground.

That's one of the biggest problem with some of the aging vehicles the plastic gets brittle part of the problem is they change the chemical composition of the plastics to make it cheaper also in the molding process there are Gates that run plastic to the parts themselves they regrind the plastic that's already been heated through heat cycles and grind it back into the new plastic pellets the problem is it makes the plastic brittle not a good idea but they can save a little money and they don't care what the end user ends up with have a great day

Those that can't do teach have a good day

[@thomasedwards3372]

Good Job as usual.. thanks for the class...

[@marktompkins3180]

Simply amazing! I am in awe sir! Thank you very much.

[@tabbott429]

Amazing camera skills! You the man! Thanks for sharing! Makes me appreciate my 2006 F150 4x4 with the old shifter handle on the floor that always works and a 99 cherokee. pull the handle and go! Sad the complexity engineered into some things for negligible benefit

[@OcRefrig]

ill take mechanical simplicity over electronics for reliability any day ! Especially under a truck , Exposed to the Elements & possibly underwater at times. Motors & wiring underwater , not advisable ! manual linkage Ftw !

[@squeaky61]

I appreciate how you take such professionalism in your trade. I work on my own stuff because I am pretty thorough and feel I work with care. I would have never figured that out. I wish I had a place around my area I trust to do the work you do!

[@chrisbruske4403]

Love this channel. Very informative!

[@kangaroogod]

Always informative. Thanks

Good video, fun to watch. Richard and Theresa at Precision Transmission had the virus in Jan., of course they are both better. Theresa does the filming of Richard pulling the trans apart. Well, she has her smelling back, but Richard does not. It's funny because when he gets one of those smelly trans apart, Theresa can not hardly stand it while Richard is standing over the trans and can not smell a thing. Funny, because you mentioned you have not gotten your smell back. I guess in some trades it's better not to have your smell!!!!!!! lol

I can think of two ways it could have failed: - Motor partially shorted, overloaded the mosfet, mosfet fried short, motor burned open. - Mosfet failed short, burned the motor that failed open. I'm tempted to say the real one is the second one. There is normally in car stuff some protections, that should have kicked in and prevented the mosfet from burning.

Another great diagnosis done, you are good !

[@johnm366]

Nice video I learned a lot keep up the good work and keep the videos coming

[@MitzvosGolem1]

There is a kit to eliminate all 4×4 servos ,modules etc. A Cable engagement kit for front axel and transfer case. I converted two older GMCs and suburbans made my own kit using boat shift cables.. Nice work.

[@HFG]

I'm literally dealing with the exact same issue on my dad's 02 Avalanche. Your video is right on time. I don't have a scanner, so, thoughts and prayers lol

[@porkchop4604]

Always great to watch a master at work keep up the great videos and learning experience

[@mgcarr61camaro91]

Great videos sir ! You are a great teacher!

[@DallasNutsch]

My 2002 1500 Needed one of these modules. I always assumed it was the electrolytic capacitor that went bad because lots of electronics from this year had bad caps. It was called the capacitor plague and lasted until 2007.

[@ItsJust2SXTs]

Q515(near the B) look suspicious at 42:35, the solder is darker around it, if it's the case then a shorted mosfet could be the cause Edit: well you pointed it, I can smeel it through the screen the electronics burn smell! when a fet fail it could damage other circuit that control it, so yeah the module might be fixable but you need to clean the board, replace the fet, test it apply, conformal coating and done. it's best case scenario...

[@billgroel4463]

Great diagnosis thank you for sharing

[@thomasmurphy5906]

Great lesson, the real world is awesome, thanks Eric

[@Black3ternity]

Great to hear a shoutout to BigClive. Maybe send it over to him to inspect it? Would be fun to see a deepdive from him on this stuff. Great video as always. I bet if this fella who owns the truck wouldn't live so far away, he would be a regular customer now. Or maybe he takes the drive and stays with you. I'm always intrigued on how to diagnose these issues. Gives me as a regular customer that isn't working on his own car more appreciation for the labor that goes into this work. Keep up the great work! Cheers,

[@williamfenwick3867]

I'm just watching so I can hear Eric say "Chevrolaaay" ha ha!!

[@MrHunt1701]

Don't forget it's got the (BIG) engine lol I love it

[@charleskeenom9481]

I love the information! You help a lot with people that work on vehicles thank you very much

[@Munchvader]

Great work as always

[@strokermaverick]

All you have to is, lock it 4WD, turn the steering wheel sharp and give it some gas. If, the vehicle crabs/rocks side to side, it's in 4WD. You, can do that anywhere.🙂

[@j.markkrzystofiak9907]

With the sniffer out of action, maybe a good time to do some jobs with old hypoid oil or engine tear downs.

[@davidsoto4805]

man loving the videos your so thorough and complete

[@michaelcaughey6206]

Thanks for sharing your technical knowledge and humor...

[@John_Ridley]

Personally I'd rather have the lever sticking through the floor.

[@majorlook]

Great video showing you steps to diagnose difficult faults. Great job! Live your videos

[@kellyrak2711]
