slide issue

[al perna]

Hello WaGu ,

our slide will not extend . we have followed the troubleshooting guide of the HWH and still no luck .

tried extending with genny or bus running to assure 12 v
along with all the other recommended test .

I was wondering if the leveling jacks play a part in the operation of the slide ? on the slide control board the jack light did not light up warning of not being level .

I know there is a 3000 psi cylinder or ??? not sure what it is , but how would I check to see if this possibly is not opening ?

thank s in advance .
