John Deere 110 TLB front auxiliary hydraulic blowing fuse

my front auxiliary hydraulic blows fuse when trying to use it any one having this problem

disney · May 14, 2017

no, and I recently used a 110 tlb with phd upfront. without any issues over several weeks

No I have not. To resolve this problem you might try disconnecting the leads to the solenoid valve and see if it still blows the fuse when operating the joystick switch multiple times. If so I would look for a damaged lead shorting to the frame work. If it does not blow when the solenoid is disconnected I would also check the resistance of the solenoid valve and see if it is shorted.

Thanks I will try that

I just finished changing the two rocker switches and the joystick switch in that order. Now it will run my hydraulic hole digger in reverse but blow the fuse in forward. Do you know where to look for the solenoid valve?
Thanks Donnie

Did you try operating the machine in-between each component change?

If you change multiple items at once you can't know which has worked successfully and which hasn't.

:wrench:

Do you have a skid plate/belly pan on this tractor? If so you may need to remove it to access the valves and solenoids attached to them. I will look for pictures to see if I can point out the specific solenoid location and wiring to check.

Have you checked for pinched or damaged wiring yet? The reason I suggested unplugging the wires to the solenoids was to separate and simplify the trouble shooting. With the solenoid unplugged if you blow a fuse it is probable that it is a damaged wire you need to repair. If you don't blow the fuse with the solenoid unplugged and repeated switch operation then check the solenoid contacts to see if the coil is shorted together. Let us know what the resistance is between the solenoid coil contacts.

I would not buy any parts such as these rocker switches without knowing the reason for it. Most switches do not short to the case or ground, most fail to make contact or remain open. These particular switches are housed in plastic which would eliminate shorts to ground and blowing a fuse.

It doesn't have a skid pan I haven't been able to find one. the switches where getting bad and the joystick switch was cracked badly too. When this started I was drilling a post hole
Thanks Donnie

I would crawl underneath and look for damaged wires. A skid plate is an important item for a 110tlb without it you can easily damage the hydraulic lines. I would make one if it were me.

drware · Jul 10, 2017

do you know where I could a picture of one and measurements of one or anyone who builds them?
Did you find out where the solenoid location is for the front hydraulics is located
Thanks for all the help I'm slowly learning about these tractors
Thanks Donnie

I checked the wiring today it looked good. unplugged one of the solenoids and it blows the fuse plugged back and unplugged the other solenoid and it didn't blow. Checked the solenoid ohms on the one that blows the fuse then checked the ohms on the one that didn't and they where the same don't what to do next
call the dealer?
Thanks Donnie

Did you ohm each coil to the body, not just across the coils? If it shorted to chassis ground that would do it...

You've got to chase the ground through the switch, the solenoid coil could be failing an drawing too much current when energized also so the coil resistance isn't the tell always. It could also be shorting to the frame through the valve as the other poster suggested. Do you have the Tech manual? If not I'd get one asap as it's a valuable tool.

I would swap the coil connections and see if the short follows the coil. If it does change the coil with a new one.

drware · Jul 13, 2017

I swapped the connections and the short always stayed with the coil on the rear of the value. With both connections hooked to the coil on the front side of value was find. I looked a the parts book and it said rebuild kit will the solenoid have to be rebuild?
Thanks Donnie

I'm having a problem with my front auxiliary hydraulics again. Hadn't use it in a month hooked up my hydraulic post hole digger and it would not do anything so I tried my hydraulic chain saw wouldn't do anything either. when I pushed the rocker switch the dash would light up but nothing happens getting 12 volts to both switch and down to both solenoids. don't know where to go now. anybody have any ideas?
Thanks Donnie

@drware Donnie, I'm curious what the solution was for your July 2017 and August 2018 front aux issues. What did the problem/solution end up being?

He has been off for almost two years. So, don’t expect an answer. If you click on the highlighted user name, it opens a window with their data, and tell you teh last time they were one. drware was last on in July of 21.
