It all depends on what failed and if you have the ability to change components on a PCB.

I have a 2 year old Meos 192B TV. It works perfectly on 220V but not on 12V. What could the problem be?


I suspect there is not enough power to run the TV. Does it work in your vehicle with the supplied power lead.

How to fix a champio Generator no AC out put "?" Can you help


If it has sat, it may have lost it's rotor residual magnetism. Disconnect the rotor field wires at the AVR or on the exciter/brushes. Note they are polaroty sensitive. Connect a 12V battery to F+ and F- (note polarity) and momentarilly power from the battery for a few seconds. DO NOT forget to disconnect the rotor/exciter field wires first or the voltage regulator will be damaged. If it hasn't sat check voltage regulator, rotor resistance, and stator resistance, and for shorts to ground.

Can a 12 v supply be used for ferg.f1604levd straight from a 12v battery


a 12V battery from car??
in cars battery are actually between 14V(fully charged) and 11V(empty)
else i don't know but the best way to be sure is using a regulator (this for example)

I need a wiring diagram for fitting 12v headlights to Yamaha golf cart which is 48v powered by 6 X 8V batteries.Does it need a voltage regulator or relay?


You'll probably want to find a transformer to convert 48v to 12v. The wounds on the transformer would have a 4:1 ratio. You could do so with a regulator, but that'll burn up power and you'll need a decent heat sink to dissipate the energy. A relay is basically a switch. A transformer's the way to go.

How do I fix a mxr phase 90 (overvoltaged!with 12V universal)


My first guess would be that the zener diode is probably shorted. Also check the 2N4125 transistor for a short. Start there and update this with your results.

TRC520 CB wont power up


Hello, First of all you only have the Power wire Red, and the ground wire Black to connect for 12v DC to power the unit. If you memory power it is usually connected to a constant power source such as the cigarette lighter or continuous 12V dc powersupply off of the battery. These are the only connections that should be connected to provide power. Since the unit will not turn on I suspect that the CB's power supply and regulator have been blown. Another possible choice is that the radio was working and someone removed the antenna cable and the the RF power amplifier malfunctioned taking the power supply and regulator with it. To solve this problem, check the voltages on the wires before connecting them to the radio (these should be the 12 volt power off of the radio circuit, and the 12 volt power off of the continuous 12V connector (or the cigarette lighter). These voltages should read 12V. Connect the CB with it turned off and measure the voltages (should be 12V) Turn the radio on and check the voltages (should be a little less than 12V) If the radio does not come on then the internal power supply of the radio might be defective (In this case I would advise taking the CB to a qualified radio repair shop) I hope this helps Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

My dmr e85h display "hold" for 5 sec and turn off


The power supply board on the DMR-E85H has problems. The earlier boards suffered from leaking capacitors and the later boards from voltage regulator problems. If your machine is now dead, the fuse on the power supply board has also blown.Go to the following links for details and photos on how to fix: Replacing capacitors:http://www.fixya.com/support/t216825-dvd_recorder_frozen_please_wait_display Replacing the voltage regulator:http://www.rbjtech.net/electrical/e85/e85.htm#0 Hope this helps. My machine had the later ps board and the voltage regulator replacement worked perfectly.
