There is usually a fuse on the back of the unit. Did you check that? There may be a power supply issue to where ever you took power from? Maybe not a constant or "breaked" tap point. Go over the following site and see if it helps. If all else fails, the unit could be faulty. Go back for warranty.

Front parking lights stop working. Tested all fuses and other moduels etc in fuse areas under bonnet and inside car all tested okay. All other lights work and tail lights etc. I changed the parker light...


It could be a ground problem. See if you can trace the ground wire from the bulb socket. If you can identify which connector of the bulb socket is the ground, you can do a continuity test from the socket to the frame or body, using a multi meter. You can also use the multi meter to check for voltage at the socket; positive lead of meter to positive connector of socket and negative lead of meter (black) to a ground. If you get voltage ( about 12 V ) then the problem is a broken ground wire.

No power to right side (PS) headlight low beam plug socket, new bulb, fuse is good. High beam works, blinker works, park light works. just no low beam and doesn't register any voltage on volt meter.


check low beam fuse when switched on if it has voltage registering across the fuse ,if there is voltage across the low beam RHS fuse then it is possibly a pinched wire from the headlight running back towards inside of the car

Error 54 please


Precor Error 54, Target Pulses Lost During Operation Probable Cause 1. Blown F2 fuse.
2. Gear motor wiring is damaged or has intermittent connection.
3. Gear motor is bad.
4. Gear motor target is damaged.
5. Lower PCA is bad.
Corrective Action
  1. Disconnect power from the unit. Remove the F2 fuse from the lower PCA. Using an ohm meter, measure the fuse for 1 ohm or less. If the reading is considerably high, replace the fuse. If the fuse is blown, inspect further for the cause to avoid the fuse blowing again. Inspect for damaged gear motor wiring or a bad gear motor. Replace if necessary.
  2. Thoroughly inspect the gear motor wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  3. With unit disconnected from power, disconnect both wires from the gear motor. Using an ohm meter, check for approximately 9 ohms through the gear motor wiring. If the reading is considerably high or low, replace the gear motor.
  4. Inspect the gear motor target for rips, tears, or bad scratches. If any of these are found, replace the target.
  5. During the start up sequence, check the voltage at the gear motor. Voltage should be approximately 12VDC. The voltage should only be present between the time the sequence was started and the error 53 occurred. If the voltage is considerably low or absent and the F2 fuse proved good, replace the lower PCA.

Precor error codes 53


Precor Error 53, Can't Read Target, Can't Find Home Switch Probable Cause 1. Blown F2 fuse.
2. Home switch wiring is damaged or has intermittent connection.
3. Gear (elevation/incline) motor wiring is damaged or has intermittent connection.
4. Home switch is bad.
5. Gear (elevation/incline) motor is bad.
6. Gear (elevation/incline) motor target is damaged.
7. Lower PCA is bad.
Corrective Action
  1. Disconnect power from the unit. Remove the F2 fuse from the lower PCA. Using an ohm meter, measure the fuse for 1 ohm or less. If the reading is considerably high, replace the fuse. If the fuse is blown, inspect further for the cause to avoid the fuse blowing again. Inspect for damaged gear motor wiring or a bad gear (elevation/incline) motor. Replace if necessary.
  2. Thoroughly inspect the home switch wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  3. Thoroughly inspect the gear (elevation/incline) motor wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  4. Ensure the moving arm is away from the home switch and disconnect power from the unit. Disconnect both wires from the home switch. Using an ohm meter, check for approximately 0 ohms. Continue to monitor the home switch resistance and activate the home switch by hand. The reading should change from approximately 0 ohms to open (infinite). If either reading is considerably incorrect, replace the home switch.
  5. With unit disconnected from power, disconnect both wires from the gear (elevation/incline) motor. Using an ohm meter, check for approximately 9 ohms through the gear (elevation/incline) motor wiring. If the reading is considerably high or low, replace the gear motor.
  6. Inspect the gear (elevation/incline) motor target for rips, tears, or bad scratches. If any of these are found, replace the target.
  7. During the start up sequence, check the voltage at the gear (elevation/incline) motor. Voltage should be approximately 12VDC.

In my 1980 Fiberform, I have no power to any accessories or to my ignition, and my battery seems to have a full charge.


Check battery connections. Check voltage at fuse panel. Should have same voltage as battery. If voltage is present turn on any switch, if voltage goes away with a load follow the no voltage procedure but leave the switch on while testing.
If no voltage, check for any fuses or circuit breakers in the supply wires. Still no voltage: connect voltmeter red lead to positive at battery, black voltmeter lead to negative at fuse panel. Voltage OK problem is with positive supply to panel. If no voltage connect meter red lead to positive at fuse panel, meter black lead to negative at battery. Voltage OK problem is with the negative supply to panel.
If fuse panel is supplied voltage from the ignition switch start the voltage tests at the ignition switch.
Sometimes the positive and negative supply for the fuse panel are connected at the engine. Usually the positive at the starter solenoid, if so use that source instead of the positive battery post. Voltage must be traced from the root source to the load. Both positive and negative must be isolated and verified separately. Without one, positive or negative, there will be no voltage at the load. The load being whatever needs voltage applied to function, (light, pump, etc.)
If there is a corroded connection or wire it is possible for voltage to pass through the corrosion with no load. When a load is applied more amperage is required. The corrosion is not a good enough conductor to carry the required amperage and the voltage goes away. This corrosion can be at a terminal connection, (wire to switch, battery cable to battery lug, battery lug to battery post, etc.), internally in a switch, wire, fuse or circuit breaker. It is possible for a wire to appear to be in good condition. The outer insulation can be intact while the inner conductor is corroded, sometimes turned to green powder. This is why marine grade wire is more expensive than standard wire. Marine grade wire is tinned copper, copper conductor electro coated with tin to resist corrosion.

No electrical power at all, possible fuse somewhere?


If you check the battery posts with a meter and you have voltage, you would next check the main fuses and for power at the starter, plus the ground connections.

New battery new cabel ends on battery wires,started once now nothing no power to anything,rechecked battery terminal ends seemed ok same results


You'll need to take a meter or test light and find out if the connections are good enough to carry voltage to the starter and fuse box.
If you have lights but no crank, the circuit between the starter and key switch would need to be tested, including the neutral safety switch.
Could be a major fuse or fuseable link wire has melted.

Cig socket has no power fuses are ok


Use a volt meter or a test light to test voltage. Connect negative lead of meter of test light to ground and connect the positive lead to the center of cig socket. I no voltage is detected at cig socket trace wire to fuse panel and connect postive lead of test light or volt meter to positive side wiring at fuse panel.

My Whirlpool Ultimate Care II dryer does not heat up, however it does tumble. Any help would be greatly appreciated. Thanks.


There's no heat If your dryer doesn't heat, check these: Power from the house Heating element Thermal fuse Wiring Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected. Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable. Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.) Wiring A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

No power to recently installed after market radio


Assuming that you checked the fuse, is there any wires in the area that are not connected and can you check them for power? If not, ground one side of your meter and take a wire and wrap around the other lead (set your meter for dc voltage) splice or wrap a straight pin onto that wire coming off the meter. Turn ignition on and stab wires until you get a voltage reading. The best wire would be the color wire coming from the radio fuse holder. But at this point you need power so which ever wire that gives you power splice it to power input of the radio.
