Auto.resto_0 ---- boss amps...

On the inside of the amp, there is the power inlet that goes to the fuse inlet, the wires on the circuit board that connect these have been burned 'BLOWN'.when i hook it up it doesn't do anything.

Boss bv9364b audio system i have no power check fuse ckeck wiring still nothing

If the fuses in both the car and the unit are all good & the wiring is all correct & secure but you still get no power, your head unit is fried.

How do I locate and replace the internal amp fuse?

If you open the case you should be able to see the fuse pretty easily, they are the old glass tube type that are mounted on the power board. If you need a schematic you can look for the sams photofact website. That is the best one for those.

No power to unit replaced thermostat , door switches, diode on capacitor but not the two fuses continuity goes to 0

There are 2 thermostats or "thermal fuses" in it that would cause no power. One is on the magnetron, the other is above the microwave cavity near the middle. Have you checked/replaced both? You should have 120 volts between the white wire on the main relay on the circuit board & the black wire in the smaller connector on the board. If you do, bad board, if not, something before the board (fuses, thermostats, noise filter board, etc). Door switches, diode, capacitor would not cause no power to unit.

How can i get a wiring diagram for my 92 old ciera it keeps blowing the inj/coil fuse

Too old to buy the factory manuals from Helm.Com

A repair shop may have them on their data base

Try Auto Zone web site for the free stuff

You need to either learn what a short is or forget that
train of thought

You have two sides of an electrical DC Circuit-Power with the
wires & ground side, which is the entire vehicle,body,metal parts,
motor, trans, etc

Electrons leave the batteries neg post & go thru the fluids &
body before entering a device & returning on the wires to the pos

A short is a one time event & burns thru a wire or circuit board
component & then you have an open or blown fuse

So: Power or No power,Grounds are good or also open

If you unplug the injectors & measure their OHMs you should
have all of them the same & they have to be above 18 OHMs
& either terminal to its body or a vehicle ground, for your internal short

If you plug them in one at a time, you will find out which one
blows the fuse, when cranking the motor,just don't hydraulic
the motor with lots of fuel

If it goes beyond that, then yes, you need wiring diagrams

All you can do is, check the harness connectors or broken
wires, etc

You do not want to load the circuits in & out of the computer

DO NOT-- use a probe or any powered tool-- (Test Light)

Only use your volt meter or you will fry the PCM if you get it wrong

How does electric heater works? what are the concepts of electric heater.

A Heater, is a real simple circuit. There are only TWO "Active" wires in any Electrical Circuit, the Phase, Positive, & Neutral, Negative, usually Negative & We also have an Earth, the Earth & Neutral are at the same, "Potential", IE:0 Volts. So imagine it like this, from the left we have a a Power wire, the Phase, this Wire, goes to One terminal on the On/Off Switch, this is called the "Hot" side, of this switch, This switch, when operated, "Breaks" the Phase line, or circuit, From the other terminal,the "Cold" side of the Power Switch, That wire, circuit, then goes from that "Cold" side of that switch, usually, to a "Thermal Fuse", wired in "Series" this "Fuse" is "Normally Closed", when/if, there is an "Overheating Condition", this "Device" will go "Open Circuit". Thus Breaking, the Phase Power, OFF, from the "Element", or "Load". Connection. This wire then goes, from the other terminal of that "Fuse" to the "Hot" side of the "Element". Now the other side or "Cold" side of the "Element" or "Load" then goes to "Neutral", or, return. Thus the circuit is now complete. Now the Earth, the MOST important wire, is bonded to the/any metal case &/or fittings of the unit, thus any "Hot" wire that may break, or touch, the "Earth" will cause a "Short Circuit" to Earth,and "Blow" the Circuit Breaker or Fuse on the Main Power Board. Thus affording protection from shock. Troubleshooting is simply following continuity along the circuit path, and the measuring of the On/Off components for integrity, and the/any "Fuses" and the "Resistance" of the Elements. This can be worked out from OHMS LAW, Volts = Amps multiplied by Resistance. Watts = Amps x Volts. From those two simple calculations we can glean the "Resistance" of the "Load" and what it should be. Then we can measure against that to see if there is any disparity, which would indicate the fault. EG: We have a heater it is 2000 Watts, it is in USA and the Voltage there is 120 Volts. First we must get our Current draw, we then divide the Wattage by the Voltage to get our Current draw. In our case, it is, 16.66 Amps. Now we know our Amps we can workout the resistance of what our Elements will/should be. Now we Divide the Voltage by the Amperage to get this figure, which is 12 OHMS, if there were 2 elements they would simply be 6 OHMS each. Now sometimes heater have a "Thermostat" this device is Powered from the line, and using temperature sensing, it will act like a switch, that is turned on & off, when a "Condition" is met. It simply Breaks the Phase to the "Load" These "Contacts" are in series, with the Phase, and "Act" just like a/the power switch. We look for "Open" circuit where it should be "Closed" and "Closed" circuit where there should be "Open", also the "Resistance" of the "Elements" or "Load". So basically we are looking for, "Open" or "Short" circuits.

Blown amp, on circuit board, connecting fuse and power connect.

These amplifiers dont employ reverse polarity protection that most higher priced ones do.
The amplifier(s) are definately in need of repair - probably power supply - IF boss sells parts.
Chances are, however, the repair will meet or exceed the cost of a new (appropriately rated) entry level amplifier.
Just about anything can be repaired.... question is, are you willing to pay?

No Power to the Amp

open the amp and look for a fuse either on a circuit board or on wires inside. trace power wires onto board.
