0 volts on pin 9 of the flyback

I got 0 volts on pin 9 of the flyback. IC561 is bad agreed?

In circuit testing of R541 and D531 isn't a reliable test. I would need to unsolder for a good test. I can unsolder and test when I replace IC561.

Base on the service manual information, yes IC561 could be defective.
You did not get the +15 volts because the TV failed to power up and the majority of voltages are coming from the flyback transformer.

Shifter stuck in park 02 ford explore.


Most likely a problem with the
Shift Interlock System
The shift interlock system prevents the shifting from PARK unless the brake pedal (2455) is depressed. The shift interlock system consists of a shift lock actuator (3Z719) mounted at the base of the steering column tube (3514). If the ignition switch (11572) is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed.
Could have a bad brake switch , do the brake lights work ?
Inspection and Verification
  1. Verify the customer concern by operating the transmission external control.
  1. Visually inspect for obvious signs of mechanical and electrical damage, incorrect component installation, and component misalignment. Verify that all circuit-related systems are functioning correctly. Refer to the following chart:

Only charges 9 volts


Hi Mcnabb491, in order to check out any main system electrical circuit, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary.
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is grounded and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the meter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the meter should read infinity. Connect both leads to the alternator meter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.
Good luck and have a nice day.

Need a wireing diagram for 149 cub cadet mower tractor it does not charge


The Battery Won't Charge or stay charged.
Several possibilities
  1. Key switch doesn't turn off the system and the battery drains while it's parked.
  2. Bad insulation on the wiring somewhere and the battery drains down.
  3. The alternator is not putting out enough power or no power at all.
  4. The battery is bad.
Let's consider the battery first. This is an easy check if you have a cheap, simple volt meter. It's much better to have an old fashioned needle meter rather than a digital. The needle is more sensitive, much quicker, and makes a clearer diagnostic tool. But not to worry, for you fancy folks a digital still works (sometimes the results are not as easy to decipher).
  1. Set the meter to DC Volts.
  2. Attach the red and black leads of the meter to the positive and negative posts of the battery. Most modern day digital meters don't care if the polarity is correct or not. However, if you have a needle meter, best to put the positive of the battery with the red wire of the meter; otherwise the needle will not be happy with you.
  3. Note voltage. It should read near or above 13 volts if the battery is good and fully charged. If it reads below 12 volts the battery needs charged or it has bad cells. If after charging a few hours, the voltage is still below 12 volts then the cells are bad, replace it. That should solve your problem. If not...continue.
  4. "Load Test". Turn the key to crank the engine while keeping your eyes on the meter. Whether the engine cranks (turns over) or not, the meter should not fall much below 11 Volts. If it falls below 10 volts or worse yet below 9 volts, the battery has a bad cell or two. Replace the battery, charge it, and repeat the test.
  5. If the engine starts, rev it up and watch the meter.
    1. If the charging system is working the voltage on the meter should quickly rise above 13 volts.
    2. If it rises up strongly towards the 14 volt range this indicates the charging system of the machine is working.
    3. If it plays around down near 12 volts you are reading the recovered voltage of a good battery, but the charging system is not working.
    4. If it simply stays below 11 volts, the battery and the charging system are both suspect.
      1. Charge you battery.
      2. Repeat the test.If you get the same results...continue
      3. Replace the battery.
      4. Fully charge it,
      5. Repeat the tests before worrying about the charging system.
Note: if the battery falls below 9 volts the fuel cut off, a black cylinder on the bottom of the carburetor (if your model has this), will cut off the gas supply to the carburetor.

If the battery passes all the tests and you still don't get 13-14 volts of charge it's time to test the charging system.

Small engines have 3 different possible alternators, standard circuit, dual circuit, tri circuit. I would need the exact engine model numbers in order to precisely answer your question. Often mower models have choices for the engine they come with. In this situation the engine model is more important than the model of the mower.

Testing an alternator is fairly simple; all you need is the same multi-meter used for battery testing. Do take note: The settings for battery testing are DC Volts. The Settings for Stator or Alternator testing are AC Volts (in the 50 Volt range).
  1. Disconnect the connector from stator. The stator is right there on top of the engine under the plastic/metal fan guard. Take this off and look for a pigtail wire with a connector. Don't get the coil wire with the spark plug end.
  2. Set multi-meter for AC volts.
  3. Attach RED test lead to either pin on stator side of stator connector. (On single wire leads, attach RED test lead to the single pin.) On AC output alternators there is no positive or negative because both wires alternate from positive to negative, so either pin will do.
  4. On two wire lead models, attach Black test lead to the other pin. On single wire stator connectors attach the Black test lead to the engine or other ground.
  5. Prepare the lawn tractor for engine start (set parking brake). Start engine and run at full throttle.
  6. Check output. Output for engines of this general size run in the 30 to 50 volt range. For instance the B&S V twin 22 hp AC output at full throttle is 30 Volts minimum. Other B&S on these machines spec 40 Volt minimum.
If your voltages are not in the manufacturers range (too low), or non-existent, your stator is partly shorted or completely burnt out (open circuit). Either way you have to replace it.
A. In the picture is a single lead stator connector.
B .In the picture is a two wire lead stator connector.

Flyback


I read the other post you made and I don't belive that the flyback transformer has gone , and these models and makes from rca do have some common fixes that are found out by tech's . this problem that you are having can be in the power section , stanby circuit , protection circuit or even a horizontal output IC or some component that is causing the set not to come on . the flyback transformer would need to be tested to determine if it went bad but the power section would need to be tested first because there are different voltages that come out of the primary transformer and they go to different parts of the tv's functions and circuits , also info like what happen when it went out? and or was there a problem with it while watching it before it went out? , this can help to know what section was failing , thus start the testing in that section.
the best thing to do is to call an electronic repair shop to have a teck come out so they can determine the failure for you , as these are pretty complex sets and unsoldering and soldering , testing of and value idenentification of components is required , so if you cannot perform these then you could be putting alot of money into it and never finding the problem.
if you would like any more info , I'll bee glad to assist you

I measured 1.1V at pin 2 on IC561


Check for +15V from the flyback pin # 9, if that voltage is present; check R541 and D531. If these parts are good you should find +12V at TP98 nearby C539.
If still not voltage found, I would suggest to desolder and isolate IC561 pin 2.
