Thinking about buying one to troubleshoot electrical problems. Seems like it might be handy but at almost 200 dollars just wondering if anyone else had one and do you use it?
Direct quote from page 10 of the instruction manual:Ok, so people have used them. I borrowed one, and when trouble shooting an electric tailgate lock, ended up finding that the driver rear door lock actuator was inop and power ran through that to tailgate, so that was why the tailgate wasn't working.
Then after replacing the rear door lock I was playing with the powerprobe, and
I would probe a wire at the tailgate lock actuator, the green neg. Light would come on, then when I applied power via powerprobe, it would trip the breaker in the powerprobe. What causes that?
It pays to RTFM. You found a good ground, and when you depressed the power button it made a direct short to ground which tripped the breaker. For more specifics on what will trip the circuit breaker read page 9. http://www.powerprobe.com/powerprobe/literature_files/PP3_English.pdfCHECKING FOR BAD GROUND CONTACTS (PPM)
FOLLOWING & LOCATING SHORT CIRCUITS (PPM)
Probe the suspected ground wire or contact with the probe tip.
Observe the green negative sign “-” LED. Depress the power switch forward then release.
If the green negative sign “-” LED went out and the red positive sign “+” came on, this is not a true ground.
If the circuit breaker tripped, this circuit is more than likely a good ground. Keep in mind that high current
components such as starter motors will also trip the circuit breaker.
you multi meter can hot jump [email protected] 5-10amp and then instanly reverse polarity with one finger and not setting anything down or turning a dial???
he kept getting 12v because while he was "cheking it" he was acutaly applying 12v to it. you dont need to operate the switch to take a reading. if the probe is pluged into a power source it is read to read.
very very very handy and i love mine. they make a few different probing and connecting leads/tips.
i wish the ground/neg at the hand set was about 6-10" longer though, it just barely reaches to the tip of the probe so that if you ar trying to run a small motor you often pull the ground off when moving things around and getting into position.
it is an impromptoo [sp] multi. continuity, voltage, apply power.
it does need a solid 12v source and does not have a battery in the hand set. how ever, even the basic kit includes a 25' extention lead and that will allow to reach all the back on a typical longbed pick with a 20' trailler.
If I was working on stupid shit all day like trailer lights, tailgate locks etc I would probably want one, but for complex troubleshooting of the machines I work on there is no use for me.A guy at work was using power probe to figure out a no-start issue on a Gehl; he kept getting 12v where he was supposed to couldnt figure out why it wouldnt start.. double checked everything with a multimeter and found no voltage at all.
A power probe seems like a "multimeter for dummies" type of tool to me; I will never buy one; my multimeter does everything a power probe can do and more
Cool, I read the original patent application and the user manual directions (do a separate search for the manual, it comes up in google docs) The only parts you would need to make your own are a 25 Ohm ballast resistor and a momentary on switch. Good idea, but I'm not going to spend $88 on a resistor and a paperback on basic DC troubleshooting.If I was working on stupid shit all day like trailer lights, tailgate locks etc I would probably want one, but for complex troubleshooting of the machines I work on there is no use for me.
I find a current clamp and a loadpro test probe to be far more useful than injecting 12 volts into a $2500 ECM.
