 To keep a long story short.   I was in the process of cleaning up my mill, wich I haven't run in a long time.  I have a lt70 with the cat diesel and the starter doesn't seem to be getting any power.   I have power to the controls but when I turn the key I get nothing.  Not even a click.  Any suggestion on where to start.  Also my hydraulics wont respond either.  I can hear clicking though coming from the hydraulic box.  I look forward to your responses.

My Kubota wouldn't start a couple weeks ago.The lights worked,had 12.6 volts in the battery and at the starter.It turned out the battery had an internal short.We put jumper cables on it and it fired right up.I'm grateful for a savy mechanic.Might not cure your problem,but someone will be along with a solution.

Check the battery voltage.  It may be dropping down under load.   Hydraulic pump and starter draw lots of current.
Been there, done that.   Never got caught [/b]
Retired and not doing much anymore and still not getting caught

A test light is a good friend in these situations.

I would check fuses , grounds , battery , has the mill gotten wet ? any corrosion on contacts ? A low battery can cause all kinds of issues . I hope this helps . As a side note do not attempt to use hydraulics with low battery trust me it aint good ......

Battery is reading 12+ volts even had a battery charger on it.  I also tried another battery.

I hate to say it,, but unless you like chasing your tail,, give wmz a call, it would cut down on a few circles.
only have a few chain saws I'm not suppose to use, but will at times, one dog Dolly, pretty good dog, just not sure what for yet,  working on getting the gardening back in order, and kinda thinking on maybe a small bbq bizz,  thinking about it,

Follow the power source. Sounds like a bad connection somewhere. Sounds like a bad ground to me.

The one on the bottom rail.
Gunk gets in there not allowing it to make a ground.

If that don't solve it get out a volt meter and start at the battery and work your way thru the starting system.

    Hello,
    Sounds like everyone has you going in the right direction. Here are a few things to think about.

    I would start here first.

    Facing the radiator on the right side of the Cat engine remove the black cover that has the glow plug relay and some other electrical connections. There is a manual reset circuit breaker that may trip. It will cause a no crank issue. It is a small tin box with red wires attached. There is a black button on the side of it. You should be able to push the button if it tripped.  You should hear a click.   

       It takes at least 9 volts to excite the starter solenoid.  Check voltage at the blue wire on the starter. Turn key to 3 no voltage then go back to the circuit breaker. There is also a breaker in the control box under the key switch.

         Ground for the mill and the hydraulic pumps are through the bottom rail. The engine grounds run through the mill from the battery ground post to the engine and more.

        If the bottom rail has rust on it remove rust with wire brush on a drill. I use a 4" grinder with a stiff brush attached to the arbor.

        I would not start here but something to think about.
    I assume this is a early LT70 there were some wiring issues in the control box under the water bottle. The connector would saw through the wires.  :o

        There has also been some upgrades to the fuse block. There are two Red wires on the top left post, Are they loose? The fuse should be on first then the wire terminal then a lock nut. The nylock nuts usually melt and the nuts come loose. I toss them and add two nuts or a swedge lock style nut.
    If the fuse stud is loose or the block is burnt replace it.

         If the fuse has black in the center then you have the new design fuse block. No worries if you have this.

         A 12 volt test light and a volt meter works well if you call WM and they ask you to do some tests.

         I always start at the battery, check voltage if it is 12v and then you put a load on it. ( Engage the starter or the hydraulic pumps) It should drop but not more than 3 or 4 volts. Then move the the fuse block. Old style fuse the top fuse is the control box and the bottom one is the hydraulic pumps fuse. Do the same voltage check here.

    The hydraulic pump may be related to the engine no start or be something else. These systems are separate after the fuse block.

       If everything checks out. Then call us. I could keep going but that will get you started.


    Hope this helps.

How do you know your battery is in good shape?  Hydraulics that only click, wouldn't be that crazy for the starter not to do anything.   I'd take a jumper and test the spark from the red power wire on the starter to the frame.  Or better put a meter on it there.

I agree with Marty on that little button inside the black box. I had a low battery on the mill, went to start it and didn't have enough juice so it blew the breaker.

Any little critters take up residence in there during your absence? this should show up during your testing process, but its always good to have a look at all the wiring that is exposed and in places where rodents can hide.

Again I will say this thread shows just how much/ how far the good guys at WM go to help the users get the machines to do what they are supposed  to.  As a 70 owner I know that sitting idle is a bad bad thing.

When my 40 sits idle mice try to take over :( And rust, and a few other ills. Letting your mill sit is almost as bad as borrowing it to your brother in law :) (mine sits a lot).

Put some drier sheets in the air-cleaner and some near your
engines covers and control boxes.  Keeps the rascals out.

So you're saying....if I have a hole in my laundry room where mice have been creeping in, I can stuff that hole with drier sheets and that will keep them out? This is a problem my wife has and she doesn't know what to do.

I just picked up some more moth balls. That keeps them out of the control box.

Up date

The breaker on the side of the motor was the issue with it not starting.

The solenoid  that powers the hydraulics was bad.  New one on order.

Thank you all for all your suggestions and helpfulness.
