Case starter acting up

I have a Case 480D backhoe. Starter drive was slipping and a new drive could not be found. A new starter was close to $300.00 so I decided to take a chance on a Chinese made replacement. I installed the $125.00 communist made junk starter and the solenoid was clicking sometimes and was getting worse. I removed and cleaned contacts, although they looked good, and it was virtually the same design but much smaller, but it started well for a short time.
Now it will "click" once in about five starts and I can short contact wires at starter and it starts instantly every time.
I replaced the ignition switch and the solenoid wire going to the starter.
Same problem but will always start by shorting solenoid.
All contacts are clean and bright and fit snug.
Really reluctant to pay upwards of $300.00 for a new starter and still have the problem!
I was not having a solenoid problem with original starter.
Just doesn't make sense that it will start by shorting but not with ignition switch. In all my repairs, this problem was always ignition switch or it's wiring.
 
Try adding a Ford type solenoid ahead of the starter solenoid. Power the "S" terminal from the ignition switch wire. Run a #10 wire from the battery connection on the starter to one of the power lugs, take the other power lug to the solenoid where the wire from the ign used to go. That should give full battery voltage to the starter solenoid, just like jumping it across the battery terminal.
 
Sounds like you don't have enough amperage to
pull the solenoid in for the contacts to make full
contact. When you jump the two big lugs on the
starter solenoid and it starts the engine means
all your battery cable connections are good so
this leaves the small wire that activates the
solenoid. You may have a bad wire from the starter
switch to the solenoid or just a bad end on one
end of this wire.
If you have 6 volt batteries hooked in series
convert them to 12 volt batteries in parallel. The
problem you're describing shows up all the time
with 6 volt batteries hooked in series to make a
12 volt system.
 
Put your volt meter on the wire coming from the
switch or button to the solenoid. Sounds like you
have a low voltage problem.
