    Komatsu WB140-2N transmission problem

    Did you ever get a response? Seeing the same on our WB140-2N

    Takeuchi TL230-2 won’t start

    Thats generally my problem, I see parts on the wiring diagram, can’t find them on the machine. Down by the battery there are 3 fuses, each covered by a tan plastic cover. The fuses are mounted on a metal plate, the SF relay is behind the plate. Here is a photo, I had to replace one of the fuses...

    SF relay is the safety relay, it applies power to the start relay.

    Pin diagram of safety relay, service manual doesnt have this info.

    I believe I wrote about this earlier. The alternator has 3 electrical connections - Heavy wire, carries the alternator output to charge the battery - Swiched 12V, which excites the alternators field allowing it to generate power - Control line (don’t know what it’s called), switches to ground...

    Did you check to see if the alarm / oil pressure light came on? If it does it suggests a problem in the safety circuit, where the alternator isn’t pulling the safety line down when powered but not turning.

    With The key in the run position after maybe 30 seconds does the oil pressure light come on and an alarm sound (assuming the alarm hasn’t been disconnected)? The current will be much lower without it cranking, so there should be virtually no voltage between the negative post and frame. Why was...

    Simon is correct, also even a slight voltage difference between the ends of the cable will give a wildly wrong resistance reading, plus the resistance of the test leads & probes is probably 100X higher than a good ground cable. Measuring voltage drop under load is the only to test a heavy cable...

    So were you able to get it to start & operate, but now have a new problem? The voltage from the battery negative post (not the clamp, the actual lead post) to frame when cranking should be very low, maybe 0.1V. If it’s 2V that means only ~10V is available for the starter less whatever other...

    The round object with the two heavy wires is the main power contactor. None of the three relays shown have been replaced recently. The battery negative connection is connected to the frame on a stud right inside of the rear door opening by the battery. A good starting point is to take the lug...

    Takeuchi TL230-2 won’t start

    Looking at the wiring diagram, one terminal should have 12V with the key off (heavy wire), one terminal should have continuity to frame (small black wire). That leaves two terminals. With the key switch on both of these wires should have 12V. If the smaller wired terminal doesn’t have 12V, then...

    Do you have a volt meter? This is easy to test.

    Here is a snippet of the wiring diagram, showing the battery, contactor, key switch and fuseable links.
