    No Lights When You Turn Key-Kubota M4050

    I should have mentioned that they switched alternators. The original Kubota alternator has a separate generator. They switched to an AC Delco with a built-in generator...so I guess the wiring reflects that.

    No Lights When You Turn Key-Kubota M4050

    If you turn the key on my tractor nothing happens. No lights. The battery is fully charged. On one occasion I was putting the battery cable back on the battery and there were sparks. Could I Have zapped something? I replaced the fuses. The fuses are confusing because they are very hard to...

    Alternator Bolt

    I thought it was odd that it didn't come with a nut on that bolt.

    Alternator Bolt

    I bought a new alternator. The top bolt (on the new alternator) that connects to the slide adjuster (Sorry no idea what the official name is) will not loosen. The bolt isn't long enough to get a nut on it. Will it come off with an air wrench? Thanks for your help.

    Alternator wiring

    They have aftermarket regulators available. Would it be worth it to get one and use the 3 wire alternator?

    I am replacing the alternator on my Kubota M4050. The old alternator had posts marked 1 &2. The replacement is marked E F & N. How do they match up? Thanks.

    m4050 Random Starts

    I have owned the tractor for less than a year. It’s hard to know if it’s original or not…but I get your point.

    m4050 Random Starts

    Yes, it is from 1982 to 1985 so it doesn't have a lot of bells and whistles or electronics. I will see what I can do with a meter. Thank you.

    Just to be sure I'm doing the right thing....you mean where the negative cable attaches to the tractor? It looks like it could use a cleaning. Thank you.

    m4050 Random Starts

    I have had problems getting my m4050 started. The battery was checked and it was fine. I replaced the starter because it was making a whirring or grinding sound. Once I replaced the starter and the battery was charged the tractor started at the first turn of the ignition the first few times...

    M4050 Won't Start

    Well, my tractor started tonight. I had tried to get it to start so many times with the old starter I drained the battery. I took the new starter off to see if I had knocked a wire loose but there was nothing loose…and since I had to swap out the terminal I decided to charge it. Thanks to all...
