The amplifier likely has shorted output transistors. Going to a higher rated could easily have caused more significant damage.


Let me know if you have any other questions.

Your first mistake was to listen to a parts person at Autozone and actually buy the part he or she suggested, THEY ARE NOT TRAINED TECHNICIANS! You need to take this either to the dealer or a local transmission repair shop. In Calif these parts stores can't do the testing and can't hand out advice on vehicle repair. There is a reason why a trained automotive tech makes $30.00+ per hour and they make maybe $10.00, it is called training.

Just off the top of my head I will say your device stops working at night because it is solar powered. No sun, no power; no power the pump will not work; pump not running, the water will not run.

There is lots of evaporation from the device and that is why you have to constantly fill it.

The fun is suppose to be in the maintaining of it, the caring of it.

Thanks for your question @ FixYa.com

Sony midi Hifi switching itself off


These digital amps are very prone to blow if the speaker wires are shorted so Sony appear to have put in a protection system that mutes the amp when this happens. You have to unplug the amp for a minute till the light goes off, make sure no speaker wires are touching each other and then it should work ok. I found the same problem with one I bought 2nd hand.

Lincoln SP-135T Does nothing Please HELP


a mig welder must have a good ground to work, also dont try using rusty wire it will jam in the liner, have you checked you are getting wire feed from the neck? just pull the tright and with the welder on it should feed out, if you can stop it its to loos tighten up the pinch roller, is there power on this wire feed? i have often seen new welders strick up the weld with to slow a wire feed and to many amps running, what happens then is it burns the wire away in one flash, right up inside the welding tip and every thing comes to a grinding holt then???? it can and often will just weld the wire into the tip,, witch may mean a new tip is needed, take off the shroud and try to unscrewing the tip if no wire comes out when you pull the triger
as the wire is stuck or welded to it you may be able to get it out still??? but its best to fit a new one in, go one size bigger than the wire your using at first as you are sure to get it very hot??? untill you get the hang of welding,,, use a good gas mix like argon light it will weld stanless steel as well?? but co2 works well on miled steel only, the problem with co2 is its a cold gas and you need a lot more amps to weld the same thickness of steel use it at about 2 to 4 psi only indoors, out doors use it at 4 - 6 psi and if out doors keep out of the wind as much as you can or it will only blow the gas away from your weld if that happens you cant weld without gas being there as a sheeld, dont try using a no gas welder they are like the devel having a bad hair day to use,
even a good welder wont like one? there c*ap!!!!
only try welding clean steel not rusty steel or it will spit like mad at you and you wont get a good weld,
if at all,,one of the most common fults that is
but i bet you have weded the wire to your tip?
its so easy to do at first,,only two word of warning
keep well raped up, sparks well fly and were gloves',,,
and keep your head sheeld on well over your eyes dont ever ever look at the welder when welding it will burn your eyes realy bad and you will wake up in the night feling like some git has just pored sand into your eyes and its going to hert like hell for day's,,,
i find the solor head sheel is far better, its nearly clear when not welding and go's dark in milliseconds you will like them as you can see what you are doing right up till you strick up the ark then it go's dark,,
most welders last for years iv had mine for the last 35 years it a clark 150 turbo mig, and iv doged it to death too,,,
the only thing that could realy go wrong inside them is the rectifier, mains coil or a relay,, not much left in it to go wrong ,
and now iv bored to death good luck with your welding ,,i hope this has helped you out
