Tbi fuel shuts off when the light are turned on?


Sounds like a ground or high resistance problem . You have to look at a wiring an check to see if the headlamps an the PCM/ECM share a common ground circuit .Go to http://www.bbbind.com/free_tsb.html free wiring diagrams ! Then go on youtube an watch videos on voltage drop testing , basic automotive electrical trouble shooting , how to read a wiring diagram . The get yourself a DVOM - digital volt ohm meter an then test the circuits involved . The PCM/ECM control the TBI injector . Also check the battery an cable connections .

I have a GE side by side refrigerator that makes and dispenses ice ok But does no dispense chilled water. How do I trouble shoot if this is a frozen dispensing tube issue or something else.


The problem could be a faulty water dispensing solenoid valve. On the back of the unit, usually at the bottom you should see where the water connection from your house is located. Turn off the water supply and check the inlet screen to the valve assembly, it may be plugged. If this is okay, if you know how to operate a volt-ohm meter you could check for resistance on the solenoid coil. If you can't check with a meter, you could remove the assembly and take it to a parts store and have them check it. If it is bad, you can purchase a new assembly.

AUTO FAN NOT WORKING BUT FAN ON WORKS


Sounds like the thermostat is either defective or has a bad connection. If you are familiar with using a multimeter (volt-ohm-current meter), it would be the device to use to trouble-shoot this problem. MAKE SURE THE HEATER IS UNPLUGGED!!!

With the meter set on Ohms, and the heater set on auto, set the heater to its lowest temperature setting. You want to see no resistance (close to zeor Ohms) when check across the thermostat (the temperature knob mounts on it). If you see high or infinite resistance, the thermostat's open and therefore defective. If the thermostat checks out OK, continue checking with the meter. You should have about zero Ohms between the hot pin on the power plug (the narrower one in N. America) and the heater motor lead. If it's open (high or infinite resistance), keep the one meter lead on the power plug and trace back, checking each connection until you find the defective one. Don't rule out a broken wire, maybe inside the insulation (but unlikely).

Driver's window switch not working. Feels different. How do I trouble shoot to tell what I need to repair/replace? Can I use the window switch on the passenger door to replace driver's window switch?


Replace switch. Passenger switch
is not wired the same, will not re-
place the drivers side switch. You
can check for continuity if you have
a meter that has voltage, resistance
readings on it. With the switch pushed
to the on position put a red or black
wire to each prong . If the meter
stays at zero or does not move
the switch is bad.

Trouble shooting Samsung REF. Model RS267LBSH


when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature.
May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..

Another item to check with a meter is the heating element itself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS .

Lastly check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?

Using a volt-ohm meter check the voltage in the wires connecting to the troubled valve, with the station on. You should be getting about 24-28 volts AC. If not, check for this voltage back at the controller/timer. If present at the controller but not at the valve look for a broken or corroded wire. If you have the proper voltage at the valve you will need to check the selenoid for resistance, which should be 18-25 ohms. Or, you can just replace the selenoid in the valve for about 10-15 dollars.

Water is too cool for shower. Is there a thermostat?


I do not believe there is a separate thermostat. However the installation guide: http://www.eemaxinc.com/assets/files/FLOCO-install.pdf gives some trouble-shooting steps. More detailed trouble-shooting is here: http://www.eemaxinc.com/assets/files/floco-trouble.pdf

If the indicator light is off when the hot water valve is open: check your circuit breaker and the flow rate of water into the water heater (it must be over 1/2 gallon per minute). If those are okay, check the resistance of the element with a multimeter - 20 Ohms or less is good, 10,000 Ohms or so indicates a bad element. The trouble-shooting guide indicates the proper points to test.

If the indicator light is on, then check the flow rate at the shower head or faucet (reduce the flow until the water comes out hot), check that the unit is installed to the correct voltage supply and the resistance of the element.

If those are okay, then check that the printed circuit board is correctly installed and that the inlet filter isn't clogged.

After that, it's call the company for their technical support.

P1370 and p1350 trouble codes


P1370 Ignition Control (IC) Module 4x Reference too many pulses

P1350 Ignition Control System

Ok, these codes are signaling a malfunction within the Ignition control module. it is sending way to many signals to the coil. i recommend testing the coil for damage and irregular resistance. i will explain how to do this below. i would replace the module as well. The control moduel is Located Under hood, center, rear engine area, above valve cover, mounted in base of ignition coil pack

Ignition Coil Test Procedures__

Ignition Coil Resistance

* with the key off and the battery lead to the ignition coil disconnected, use an Ohmmeter to measure the primary and secondary winding resistance of the ignition coil. when checking the resistance across the windings, pay particular attention to the meter reading. if the reading is out of specifications, even if it is only slightly out, the coil or coil assembly should be replaced.
* To check the primary windings, calibrate an ohmmeter on the X1 scale and connect the meter leads to the primary coil terminals to test the winding.

* An infinite ohmmeter reading indicates an open winding. The winding is shorted if the meter reading is below the specified resistance. Most primary windings have a resistance of 0.5 to 2 ohms, but the exact manufacturer's specifications must be compared to the meter readings.
* To check the secondary winding, calibrate the meter on the X1,000 scale and connect it from the coil's secondary terminal to one of the primary terminals.

# A meter reading below the specified resistance indicates a shorted secondary winding. An infinite meter reading proves that the winding is open.
# In some coils, the secondary winding is connected from the secondary terminal to the coil frame. When the secondary winding is tested in these coils, the ohmmeter must be connected from the secondary coil terminal to the coil frame or to the ground wire terminal extending from the coil frame. Many secondary windings have 8,000 to 20,000 ohms resistance, but the meter readings must be compared to the manufacturer's specifications. The ohmmeter tests do not indicate such defects as defective insulation around the coil windings, which causes high-voltage leaks.
