Troubleshooting and Diagnosis - Cam's Approach (Truck Talk #1)

Рет қаралды 41,448

Жыл бұрын

Heavy Duty Mechanic, Cam, talks about how he approaches trouble shooting and diagnosis. Relating this talk to real life scenarios that he's run into, Cam gives us a look inside his thought process on how he's able to solve problems that come his way. Before you start throwing parts at it, start with the simple stuff, perform "swapnostics", and understand what a part is supposed to do, and why it may not be doing that.

As an ex Aviation Electrician, great tips especially about breaking it into sections. After checking the basic stuff, then the next thing is to grab a diagram and a sharpie or highlighter. Circle every component and trace out the wiring. Find a central test point and start there with the multimeter.

Especially in fleets where you have several units that are the same make and model. If you find the same problem on 2 of them, guys can jump straight to that on the rest.

Always check POWER AND GROUNDS. If it has power and ground, more than likely that component is bad. If it doesn't have power or ground, use a voltage drop to test for high resistance or resistance measurement for an open. That'll take care of most of your electrical problems

@musahawkins8765 Жыл бұрын

Mostly yes but it depends what your testing with if your on a 12 v system and a component works with 12v and its only receiving 7 due to corrosion you could be fooled by that as well but you are correct just wanted to add for anyone who may be looking for information

@andyperkins2523 5 ай бұрын

That's why he said test for a voltage drop cause if you're only getting seven then the voltage is dropping indicating high resistance which is corrosion or loose connection, burnt area like I said high resistance.

All I was doing was replacing a trunk harness for a recall on a mustang, after I got done, the rear camera was inoperative. I double checked all my work (splicing 10 wires and connecting a coax cable) and it was all good, thought I verified power and ground to the camera, still inop, then I started going to the bcm and the wires between the camera and the screen.. went back and supplied ground to the camera, worked perfect. The harness they sent for the recall had an open on that wire. Routed ground to an eyelet nearby, because any ground is good ground, worked perfect every time I tried it.

Had to get a coworker to come and assist me and he went right to the gasket and fixed it first shot, of course the client had to be standing right there too.

Electrical troubleshooting steps i use- 1. Verify customer complaint, and ask a crap load of questions about the issue when talking with customer. 2. Know theory of operation on what im troubleshooting 3. Start by looking for what is right in the circuit. 4. Texas 2 step dmm at battery ground long dmm lead to component or powerprobe works great, chevk for power? Now how about a ground? Is there any indication of voltage drop instead of 12 i have 7 volts that kind of thing is my ground close to 0 volts, veejer enterprise method btw 5. Dan sullivan methodology keep it simple its only 3 possibilities for electrical issues short, open, high resistance thats it dont overcomplicate it just because there is a crap load of wires its not all connected each section has its own circuit, just a fuse-relay- power- ground etc... for every circuit just keep calm and test on. 6. Swaptronics 7. Scanner danner method how is it controlled what is its job power side switched provide the power or ground whatever just bypass it look for scan data pid change signal circuit integrity test look his stuff up pull up or pull down design 8. Journal it especially if it causes you grief next time you will have notes and writing it will make you better at remembering it 9. The complicated crap is because joe smoe did something to it playing mechanic and caused it to be complicated this is basically the only time it gets complicated 10. Never trust anyone one if troubleshooting with someone they say i checked that already check it yourself they are probably lying. 11. Call service section about their equipment like for example Cat dozer issue, call Cat ask them questions when stumped Now this works in other areas not just electical 20 yrs of fixing crap and a lot of money/ research enjoy and dont be a no it all no one likes that dude be humble

Know the system, you may need to spend a few hours reading before you touch anything. Get your information direct from the manufacturer whenever possible. Understand the diagram & components. Keep it simple, 90% of problems are basic issues. Can’t tell you how many machines I’ve fixed with a cheap part after other mechanics already replaced pumps, ecms, valves etc…

I’m stumped someone help

@nickjeldness1678 Жыл бұрын

A little late, but I'm a Cummins field tech and find that more often than not you have something pulling your termination resistance down. On most Cummins engines the turbo actuator is one of the termination resistors. Always double check the diagram and check your resistance out and check your actuator itself. Also battery voltage is key. Weak batteries have fucked me a time or two. More often than not the part throwing the code is not the part that's failed on a 1939 network. I constantly find other modules on the network that are failing and pulling the resistance down too far for modules that update more frequently. Make sure you're making the ecm run the diagnostic for clearing the code when you finish repairs as well.

@nickjeldness1678 Жыл бұрын

Oh also Cummins has been updating ecm calibrations to have more tolerance for network resistance ranges. Essentially just writing the problem off. So that can likely be a part of why you're seeing the success rate with cals.

Buddy asked me about a Hitachi 120 Excavator, I told him I was to busy . But he had it at dealer and said spent 8k $ and still not fixed! So if he reaches out fast or trys to dig fast the machine dies. But if he runs it easy it stays running but digs slow. Changed all filters, diesel and Hyd, cleaned tanks, said found nothing inside, someone told him lift pump on motor , but he said it starts right back up after it stalls. Any ideas what to look at first I can relay to him?
