T190 aux solenoid

[Bigd]

Hi, first post here. Lots of info for sure. My question is that i have a t190 that the aux hydraulics dont work. I understand the two solenoids are controlled by pwm. Can i apply regular 9v dc to the solenoids to see if they are working properly. Will they be damaged if i just wire them temporary to a switch with 9v applied to them one at a time to get me going? My machine is in a very remote area and im just trying to use an auxiliary powered auger. Its just not very easy to bring my machine to a shop or bring a mechanic out.

The way i tested mine was with the machine off, enable the aux hydraulics, pull the coil off the stem and put a screw driver in the coil and activate the aux. See if you can feel anything.
I went one step further when i knew the coils were ok, i pulled the stems and put them in the coil and powered them, nothing moved, so i knew the issue was inside the stem it's self. I pulled them apart and cleaned, worked 100% afterwards.
