1080 Case Uniloader

[ADH]

Trouble with starting. Installed new battery checked cables starter and related parts and all it will do is click but if you put booster on it and increase voltage to 16 volts it will start no problem. Should this have an 18 volt battery instead of 12 volt???

Don't have a clue what a 1080 Case skid steer is!!!!!!! An 1840? 1845C? recheck the numbers on it and repost. Case never made a 18 Volt system so Don't linger to long on that thought. You are probably looking at at bad cables, insufficient battery capacity or a starter that is borderline and needs extra amps to make the engine roll. If its a later unit with a CDC engine it has a Nippondenso starter which has proven to be an excellent unit but also can fail. Get us more clear info of the model. mEl

Don’t know what year it was made but it has Case 1080 on the side. It has a new battery, starter was just rebuilt not sure if the solenoid was done or not. Battery cables have been replaced or new ends put on, all connections have been cleaned has new starter switch. This is an intermittent problem. You can go out there at times and it starts right off and then you can shut it down and it will not start back. If it does not start you can put the charger on and put it on boost it increases the voltage from 13 volts to 16 volts and it will start every time. I think it has to be in the solenoid because you can hear it click but the starter does not turn so there is no electricity getting to the starter. But the 3 extra volts makes it work every time.

The 1080 thing has me puzzled, but in general, we have had a similar issue with the backhoe/ loaders that had originally been equipped with the Delco starters having wiring in the neutral start circuit which was insufficient in capacity to carry the amps required to energise the much superior Nippondenso starter. We add a 40 amp Bosch style relay as an intermediate solenoid so that battery voltage is applied directly from the relay to the start terminal on the starter. All the current that the original start circuit has to carry is the small current required to energize the winding in the relay. The relay shunts the heavy current direct from the battery cable at the starter to the starter solenoid tab to kick it in. I believe that if you were to take a voltaqge reading aqt the kick in terminal at the starter to ground that you will find it quite low when the swith is held in start but not energising, did you try that test?

What market are you in? I suppose that there are models world wide that maybe don't match the numbers sold here in the states. If you could post some pictures that would be educational for me. I have spent my whole working career with Case and this one leaves me clueless to that model. Anyway good luck and keep us posted. mEl

Back to reality. It should be 1840 and not 1080.
I am visiting brother and it is his machine and i just misread the number and just thought it was 1080 not saying I can't read but I sure swapped those numbers. Never the less the trouble is right and the things we have did are right but the thing will not start unless the extra voltage is there and the new battery is cca 1125 and ca945 amps the old one was the same. Sure appreciate the help but it looks like he will just have to live with it until I can get back over hear next spring to work on it for him. I will print out your reply and he can show it to the shop where he has work done and maybe they will correct it the next time he has to take it in for work.

Ok, Im bettin the voltage to the starter post that kicks it in is low, that could be a bad connection at one of the harness plugs under the seat, As I stated before this is a common problem and we correct it with the relay in the BH/LDR tractors. This is not normally a 1840 problem though. mEl
