Testing the TK Tar Baby

TinselKoala · May 14, 2012, 10:53:06 PM

@MH: this, I believe, is the signature of a mosfet that is failing by shorting gate-to-source. It may be in the process of failing right in that scopeshot there.

Either that or there is really something wrong with the FG. Or maybe she's got it set to make a positive ramp, instead of a square pulse. Offset negatively of course.

TK? I nearly missed this. You and Humbugger share the same 'pickle'? EXTRAORDINARY. And that pickle is all of 72 INCHES LONG? That's big enough create seismic disturbances. Golly. If you shake it HARD - then I reckon that it'll impact on the only fault line in all of South Africa - which starts at about 7 kilometers from where I live. That means that we could all experience its shock wave. Ground moving - so to speak. In fact, since Eskom's nuclear power plants are ALSO located as close as dammit to that fault line - then that experience could result in a nuclear explosion and a nuclear fallout. NOW. How about it TK? There's a challenge for all your idle boasts. You could not only win your argument but you'd REALLY manage to silence me - together with a very large percentage of our Western Cape's population.

Do you see there? I have shown the origin of the PICKLE remark. Ainslie and her pet troll Wontbesober are ENTIRELY responsible for that particular bit of vulgarity... and once again I CAN PROVE IT all the way down the line. And like a widemouth bass rising to a plastic worm, she took the bait and PROVED her own vulgarity.

Haven't you ever seen a grown man shaking a pickle before? Don't come to any Texas barbecues, then.

You know, hasn't Ainslie been saying that she has had _absolutely no evidence_ that her batteries are discharging while running and heating the load?

Well, I've already posted one place where she admits to seeing a voltage drop while running, and here's another. The "climb" in no-load indicated voltage after a heavy drain is absolutely normal for lead-acid batteries, of course. But the DROP in indicated voltage WHILE IN CIRCUIT and running in the high heat mode, coupled with the obvious current indications on the scope traces.... and coupled with the proper understanding of the schematic in use and the way it actually works.... I'd say that was pretty clear evidence that THE BATTERIES WERE DISCHARGING during that test.

Not actually TK. The drop in voltage CAN occur during the running. CONFUSINGLY - the rise in voltage can ALSO occur during the running. Especially CONFUSING is that the rise in battery voltage was ALSO evident in that 'water to boil' test - where the last 10 minutes was evidently dissipating a runaway wattage - while the battery voltage climbed and the current discharge went to ZERO.

Did you watch how that video completely demolished your petty little ignorant claim here? No...you are too obsessed with pickles. How long has it been since you've seen a pickle, Polly Parrot?

QuoteWhat you are trying to do is to get me to believe that a function generator is able to pass current from a battery supply source via its terminal to its probe. Since I KNOW that is is impossible I'm afraid I'm not receptive to you trying to teach me or anyone else. So NO. I spare me your 'lessons'.

Got your scope back from the repair shop yet, Polly, so you can start testing and PROVING ME WRONG?

WHAT vulgarity? I am talking about the rather improbable CLAIM that a pickle can be 72 inches LONG. If any such were EVER found it would be in the Guinness Book of Records.
