Jubilee not cranking

Need suggestions. The brushes went out in the starter on the my Jubilee (30 years since last replaced). But when I put the starter back in I replace the solenoid and amp meter
also during this time. But know it will not start. Acts like the system is not getting a good ground. The solenoid will click sometimes and not turn over the starter. Other
times it not doing anything. I have put my multimeter on the wires and have 12+ volts to the solenoid. I did replace some wires that the ends were looking rough to make sure they
were getting a good connection. I am about at my wits end trying to figure out what I did to keep it from turning the starter over.

It acts like to me that it is not getting a good ground, and I did temporarily take another ground cable and place it on a different part of the tractor and still nothing.

So any ideas or suggestions are appreciated. Need to get it running so that I can plant corn next week.

Thanks in advance.
 
What I mean is if you take a jumper wire from the hot side of the solenoid to the starter, the starter will not turn. One time the solenoid just clicked, which I have always treated like a bad connection or loose ground.
 

I would put the old solenoid back on.
I was having issues with a new solenoid "for my tractor" having the wrong internal configuration. My old one still works great.
 
How large of a wire did you use to bypass the solenoid? It needs to be large enough to carry the current. The other thing to do is to make sure the battery connections are clean, both the battery posts and the cable clamps. The clicking solenoid is typical of dirty or corroded connections.
 
The wire was 8 gauge, it was big enough to carry the current for a sec. But I have lost that now.

I did get the tractor started one time, but the starter kept turning, had to pull the battery cables to get it to stop.

I have rewired, just about everything. I have put the old solenoid back on, bought another solenoid and tried it.
I hooked my hot wire to the switch straight to the battery to make sure I was getting power to the solenoid. All it will do is click. I have put my multimeter on the hot side of the
solenoid and to the starter. Meter shows 12.6 volts, push the start button and the voltage goes away as it should.

?????? What am I missing?

What is the voltage between the hot side of the solenoid and chassis ground when you push the start button?
 


The usual dfirst thing to do in this situation is to clean the battery cable connections, followed by voltage drop measurements.
 
showcrop, cleaned the cables, put a new ground cable on and have checked voltage at at every point in the circuit. Have a full 12 volts.

No voltage drop anywhere?? that is amazing!

"Have a full 12 volts." Does that mean you have the same voltage every where? I have to believe you should see the voltage at the battery side of the solenoid drop some when the starter button is pushed. If it doesn't drop, check voltage on the starter side of the solenoid while the starter button is pushed. If no voltage on the starter side of the solenoid I would suspect a solenoid issue. If the voltage is the same during that check, I would expect either a ground issue with the starter to frame or an internal problem with the starter.
 

Connected at the battery cable terminal of the solenoid (and grounded to the engine block), if your voltmeter shows full battery voltage when not trying to crank the starter but drops to zero when the starter button is pushed you have an issue with one or more battery cables or connections. You may have a bad internal connection in a cable lug. Your battery could have an internal break as well. Those can show voltage when checked unloaded with a voltmeter, but loose it when loaded as the break "opens". Have the battery loaded tested with a carbon pile tester. You don't say if you have tried a different battery or a boost.
 
I did swap battery with another one and hook my charger/boost to it also. I am going to remove the starter and make sure it is ground good to the frame.

Thanks for all the suggestions. My sister is getting married today, so I will have to to it later.

Again thanks.
 
Finally found the problems. One was a bad connection on a wire and the other was that when my dad put the new solenoid on it put a wire on the wrong post.
Got those two things corrected and it started right up.

Thanks for all the comments and advice to help with this matter.

Can you describe what wires are attached to the solenoid and in what position? I'm having a similar issue and can't figure it out
