    I've seen an interesting defence against arcing relay failure. A thermal fuse in line with the supply, stuck to the side of the relay.

    Hi i have an Curtis PMC Controller
    Model :1228-2706 Serial: 02116C-103060 24 Volt 110 Amps
    And i have looked at all the components, and the only issue i can see is Resistor R43.
    where can i found info about R43 ?
    what's the different between the models ?
    I know that the Amps and Volt must bee the same.
    Do you have any suggestions?
    kindly

    yeh, I have seen these controllers with popped DC caps, and exploded MOSFET's, but nothing this severe.

    I'm not really sure what form of storage they use on those, if the phone is dead it would probably be quite hard to retreive any data, unless its on a flash card.
    I did not know phones that old could even do video

    D-Curve breakers, voltage does not matter as long as its not high enough to arc over the contacts

  • @bigclivedotcom
    @bigclivedotcom 12 лет назад

    Odd. I've never seen PCB tracking at such a low voltage. I wonder if there was a short, but the total circuit resistance limited the current to where ithe track scted as a heating element for a sustained period of time.

    hey man always enjoy listing and watching !... just wonder I dropped a 1997 lg flip ph in water even though wasn't wet for to long can I cant retrieve vid from it if I took it to a specialist ?cheers

    Google search for a Curtis 1228-2901 manual and you can see the pinouts of these controllers, they are for control signals. you get a bare molex plug and a strip of pins with a new controller, and you make your loom to suit.

  • @Aussie50
    @Aussie50  12 лет назад

    haha, yeh we took some photos and sent them off to our lead engineer who is on leave at the moment :D

  • @Aussie50
    @Aussie50  12 лет назад

    nah, that molex plug is for input and logic, IE its Fwd/REV commands, speed potentiometer, lights, horn, blinkers, and so on. its a scooter drive

  • @Aussie50

    we use D-Curve breakers which seem to work ok on DC

  • @zforce69
    @zforce69 12 лет назад

    I couldn't see from the video, but they are 24 volt breakers aren't they?

    I have a Curtis controller 1228-2901 that i fitted to a mobility Scooter also fitted a 0-5k Potentiometer but the deadband is too wide the Scooter works fine but when you fit the Wig Wag Throttle the movement is not enough the operate the Scooter Any suggestions?

  • @voltare2amstereo

    was that circuit breaker DC rated? AC breakers don't work on DC propperly

    Does that thing use a ATX Power supply?

  • @Aussie50
    @Aussie50  12 лет назад

    they trip the breakers too easy when starting under load, it s a 600W motor after all

  • @KillerJoeFIN
    @KillerJoeFIN 12 лет назад

    Are those fuses maded for AC? They cant be used for DC! If breaker is 10A it needs at least 20A or more to trip them with big arc flash inside If they are used with DC.

  • @Jaytheozzi
    @Jaytheozzi 12 лет назад

    i dont think a 40 amp dc breaker will trip at 40 amps dc because ac has allot more magnetic flux then dc and flux is what the circuit breakers relie on. from memory you times the ac tripping current by the square root of two to get the dc current which would be something near 60 amps

    I had diode short in a PowerEdge 1650 server at work. No smoke from that part, but the short caused an inductor to turn crispy critter and THAT smoked the server room up!
    One mainboard swap and a few prayers, it was back in business. The upshot is that it got another CPU, more RAM and a second power pack to keep it all running happy.
    A fellow IT had a 1750 go in a similar fashion, but his involved the +12 tracing to the SCSI backplane. Ouch! A little more involving than just a part swap there.

    I still have a old ECU from a Audi laying somewhere, its fried as well, even i wrapped it in plastic, i still can smell it when coming nearby it.. Its still kinda awesome to keep it.. as long it stays far away lol..

  • @RODALCO2007
    @RODALCO2007 12 лет назад

    I know the type of smell you describe, very pungent. Amazing DC meltdown. DC doesn't stop and the arcing is vicious, massive destruction. Started in the relay, most likely.

  • @BarneySaysHi

    First time I saw damage like that was in a solar inverter that had suffered a lightning strike on the output. It had blown a hole right through the circuitboard. It was horrid.

  • @brianchris4
    @brianchris4 12 лет назад

    Jeeze, the board in our furnace did something similar. One of the traces completely melted down. House smelled like hell for a few days it just kept pumping the smoke through the vents!

  • @alan250250
    @alan250250 12 лет назад

    at my former job at a powder coating factory one of the industrial compressors started smoking followed by the power shutting off, it burst into big blue flames soon after with very thick choking black smoke filling the area, it burned itself out in a minute, inside was a cooked rat that chewed a wire inside, lots of black boards and bare wires, after the old guy in maintenance thought fixed it, it to burst into flames the moment he flipped the switch back on!

  • @Aussie50
    @Aussie50  12 лет назад

    yeh they are pricey buggers!, these ones are about $500 each!. the boss wasn't too happy when we accidentally doubled up our stock to 20 units one day!

  • @RandyDarkshade2
    @RandyDarkshade2 12 лет назад

    I changed the power supply in my computer after I noticed that the main board power connecter had a couple of scorched pins. The connector on the mother board was fine so I just swapped the PSU. Comp worked much better too.
    But this, this just take the cake on burnt electronics.

    I know that smell all too well. The replacement parts though cost more than platinum though mass for mass. Scary enough they came ordinary parcel post, uninsured. Each was 7 figures and there were 10 in the box..........

  • @TheFlacker99

    I put RAM chips in a toaster oven till they turned a nice brownish green. :)

    had a computer psu do something like that it all stayed in the mettle case but what a stink and mess nice thick black smoke poring out of the pc it never did anything to the rest of the pc after i put in a new used psu it booted rite up

  • @gavincurtis
    @gavincurtis 12 лет назад

    Seen this level of disaster on wheel chair controllers. Shorted relay and one shorted FET on the H-bridge and then the party gets started!!! CPU is screaming, trying to save everything.. But alas, it's too late.

  • @BoomBoxDeluxe
    @BoomBoxDeluxe 12 лет назад

    Ooooh! Eeeeew! It looks like some variac'd it, then microwaved it, put it back together, then gave you a telephone call. :D
    "....Oh, we popped it."
    There was either a fault with that like loose connections, or moisture got in & caused conductive paths where there shouldn't be.
    Yep, that one's wrecked.
    Having said that though, I'm sure it'll spark 'n' pop a bit more in the microwave. Zap it in there for 60 seconds, re-flow the solder....It'll be as good as new. :D
    Thanx for showing,

  • @Tuttomenui

    I bet that thing smells horrendous. Where I live we have a community well for water. And in the pressure tank house the power panel has these devices that are designed to burn to save the motor if something goes wrong. Motor Saver I think it is called. It is a 3 phase motor. When they burn it stinks, I had one in the house to have a look and it stank up the whole house. Nasty stuff.

  • @truebassB

  • @OlegKostoglatov
    @OlegKostoglatov 12 лет назад

    I wonder which smells worse, a burned fiberglass PC board or an older phenolic PC board. Of course this speed control also has the smell of a burned and melted ABS plastic cover just for flavor.

    @speeddemon1092 12 лет назад

    Good fucking god, ive seen some bad damage to electronics (mostly computer power mosfets that burned and took everything with them) but that just takes the cake. The worst i have personally done was the one time i accidentally shorted out a AC to DC rectifier circuit, and caused a single resistor to overheat to the point of BRIGHT incandescence. Also melted all of the solder on the small PCB it was on (4cm^2 board, was a runt), and carbonized the plastic case surrounding it.

    Ooow that conforms to a saying we had at the alternator repair shop, "If its brown its cooked, If its black its fucked !!", yep that pcb is very very frelled :-)
    Ed i know the stink you are talking about, ive had radios to repair that were burnt to a crisp in the power section, it stunk horrible, nothing cleaned the smell away, you could smell the radio with its cases on from feet away :-(
    Shame really as just one component failure and its death city lol :-)

    I mean your commenting history, at least get in and battle it out with the actual 'first' trolls when the video is initially uploaded, posting 'first' an hour after the video is up, is kinda pointless.
