    That scope is actually pretty cheap, but Pico is a good brand.....think I got it for about $150 to $180 or so a few years ago.......and it isn't really intended for automotive use, but it works for most automotive stuff.......is kind of a beginner level scope.....and pretty easy to use with a laptop, and the Pico software......if you're already fairly somewhat computer savvy, and know basic electrical fundamentals......much like using a voltmeter, but it draws you a picture......which is much more helpful for diagnostic purposes......but for most scope testing you also need specific test leads, probes, adapters, or accessories depending on what you're testing.......which can get much more expensive, but is well worth it if you have a passion for diagnosing problems accurately. If you want to learn more about using a scope or doing automotive diagnostic work......I would say to check out a KZread channel called Scanner Danner........his name is actually Paul Danner.......but he is and has been one of the best in the business for many years......many mechanics & techs learn diag from him.....including me.....if it weren't for him I might not even do diag work and might not have ever bought or learned how to use a scope.

    Wasn't this the entire point of separate sockets? To be able to measure 10A current only when using 10A socket in 10A position? And if you change the position it breaks the circuit so you have to physically move the lead to the other socket, or you will get no reading.

    Would pretty much agree, it's a bad meter design......but also honestly, the bad design has also 'saved' me in the past, where I went to check battery voltage, but didn't realize the positive lead was still in the amps port from previous testing I'd done, so when I touched the leads to the battery posts momentarily, I just got a 'spark', but no blown fuse, or melted meter, so that design has 'saved' me in the past, but not this time. From what I've heard from automotive instructors, alot of meters are internally fuse protected......but not this particular meter......it does say 'UNFUSED' on it......right below the amps port. Not really sure why some meters would be fuse protected, and some not......but seems like an intentional bad design to me to eventually sell more meters......but maybe not.....I could be wrong.

    My fix is that I always make sure to to move the dial to the 20 volt DC setting after doing an amp reading. Especially before putting the meter away.

  • @DuanesDiagnostics
    @DuanesDiagnostics3 ай бұрын

    That's definitely a smart idea to switch to the 20 volt DC setting after doing an amp reading, and before putting the meter away. From what I've seen, it seems like the amps function on most of those types of meters is usually rated at 10 amps, but might be higher on a Fluke or different type of meter, but was only 10 on that meter I fried, so I wouldn't want to go above that, but would definitely be much cheaper to replace a fuse than the whole meter........seems like on meters like those that aren't fuse protected on the amps function......that's almost engineered to fail....to sell more meters......because almost anyone that uses a meter and uses the amps function.....is going to eventually forget or not pay attention to where their leads are at......and make the same mistake I made......then BOOM!!....meltdown....and you gotta buy another meter....instead of just replacing a fuse.

    Yeah, a little scary it got that hot, enough to melt down the meter leads and ports, but didn't really seem to affect the trailer wiring at all.......I guess it's got some kind of shunt or resistor built into it that absorbs the heat from the amp draw......somewhat like a heatsink or circuit breaker that doesn't actually break the circuit until the meter actually melts down.......that seems like kind of a stupid design.......if it was fuse protected, that wouldn't have happened.......but I guess they sell more meters that way, without it being fuse protected.

On my meter, that DC AMP circuit wasn't fuse protected......otherwise I would've blown the fuse years ago, if it had one......because I've definitely hooked it up 'wrong' before in the past, going to check voltage, but not realizing I still had the positive lead in the Amps port......but I guess that meter uses some type of shunt/resistor to protect the meter up to a certain level......which I guess could be good or bad depending on how you look at it........if mine was fuse protected......it would've just blown the fuse by hooking it up 'wrong'....and not fried the meter.......so seems like fuse protected would be the better way to go......when or if I buy another one I might just add an inline fuse on the positive lead, just for the extra protection, to not fry the meter, just in case.

    @@DuanesDiagnostics You missed my point. Something occurred that caused you to suspect maybe a weak cylinder, so you decided to, rather than do a proper compression test, to do a "relative" compression test. The results of your test indicated a weak cylinder, which was the reason you did the test in the first place. Doing that crap with the laptop was a mere waste of time. What should have occurred is you heard the starter wavering, then did a compression test. You use your senses to obtain clues, then you use your tools to confirm and repair it. All your relative test did was tell you that you correctly heard a compression issue while cranking, which you still need to quantify anyway. In every case, your compression should be accurately measured if it is even the least bit suspect. The test is also useless in the sense that a confident repair cannot be initiated based on the results it provides. Hence my comment.

Definitely in other cases measuring actual compression might be necessary, and the relative compression test might not be sufficient, or other testing might be necessary, but to me, is the quicker, easier, smarter way to go at least as a first step......that's the second engine I've used it on that it quickly showed a dead cylinder, without me having to pull any parts or hook up an actual compression gauge, and have also used it to diagnose low compression due to timing problems, again....without me having to pull any parts, or hook up a compression gauge, or manually check timing.......it's actually a very quick, easy, useful, versatile test method. Actually in this neighbors case, he had already been to at least 2 reputable shops, and had replaced the throttle body, some plugs, a coil, and an injector.......also his radiator......which obviously didn't fix his truck.......and he could've avoided all that.......if either of those shops really knew how to diagnose.......and just did a relative compression test first.

    @@btasler I was actually going to buy a HF leak down tester the other day, to help pinpoint diagnose the neighbor's truck, but decided not to buy it because I don't regularly deal with alot of compression/internal engine related problems......but also thought we might get lucky on his truck and just find broken valve springs, because those are pretty common on those engines, but so are bad camshafts & lifters, and based on that and the mileage, and the noise his engine was making, and the dead cylinder........I figured there was really no need to buy a leak down tester......because if it didn't have broken valve springs, then the engine would basically need to be rebuilt or replaced anyway.....so was really no need for me to buy a leak down tester. It might've helped pinpoint diagnose it, and I definitely would've liked to know where it was losing compression on that #1 cylinder.......but either way, the engine still basically needs to be rebuilt or replaced.

The general misunderstanding though still is that pulling codes is a proper diagnosis/diagnostic, and that Autozone, and the parts stores, or my neighbor, or whoever, even some shops will 'diagnose' it for FREE.......then people question why they should have to pay for real 'diagnosis' through other shops or mechanics.......because they're misinformed that just pulling codes is a proper diagnosis and can be done for free, and all the mechanic has to do is plug in his little machine and it tells him exactly what's wrong with the car......so they end up thinking why should I have to pay for a diagnosis/diagnostics, when Autozone will do it for free?.....and then think the shops that actually have to charge for real diagnosis are trying to rip them off, when that's usually not the case.

    Yeah I have one of the more expensive ones. It's somewhat kind of a 'fancy' charger, but they call it a 'maintainer' because you can actually set the voltage you want it to charge at, and it will maintain that voltage, and also puts out alot 'cleaner', more stable voltage with very little fluctuations......unlike 'regular' chargers......they can also maintain a pretty high amp output for longer periods of time......mine has a 100 or 120 amp output.......alot of guys that do key or module programming use them....that's what I bought mine for too, but you can also use it just like a regular charger.

    Conductance testers were a time saver in a pro shop and by offering a printout they were a tool to increase sales to customers who was there for another reason. Their main weakness is state of charge, but as shown here even when that is OK they can miss gross problems. I agree, resistance style load testers are almost always better.

  • @DuanesDiagnostics
    @DuanesDiagnostics4 ай бұрын

    I agree. They are quick and simple to use, but not always accurate, even a little corrosion or resistance at the battery cables/terminals can make the test results highly inaccurate. The printout/receipt is always good to try to sell a new battery or other work. And you don't necessarily have to be an experienced tech, knowledgeable in battery/starting/charging systems to be able to use these type tools.....just hook it up, and hit the buttons, and do what it tells you to do......they're definitely somewhat handy and useful to have,in the right hands, but can also be highly inaccurate and misleading to someone inexperienced or knowledgeable in basic system fundamentals.

Seems like the parts quality has also only gotten worse since then too.....or at least in the last 15 years or so.....but much, much worse today. Is almost a 50/50 chance you might get a good part nowdays.....or at least kind of seems that way. Is pretty much expected and accepted that not every new part will be good or work right......but shouldn't be that way.
