Large slideout blows fuse

I have a 2014 Lifestyle.
Before Evergreen closed their doors I got a new relay board for the large slideout from Dexter Axle. The slide now runs smoothly. Basically cut 50 feet of wiring to 8.
Bottom line is that after 4 to 5 times of using the slide the small 20amp fuse blows that is located in the front basement.
By the slide motor is a 25amp slow burn fuse.
20 amp Fuse always seems to blow after slide is in and I try to extend it.

I have a call in to the manufacturer (Dexter) but am open to any of your thoughts.

Thanks in advance...Rob

Check the wiring to the slide drive motor, check for bare wires, "kinked" wiring, cracked wire insulation,melted wiring, connections at motor and any junction boxes. Wiring maybe getting "crimped" or connections are loose and maybe contacting a ground, when the slide is moving inwards causing a short which blowing the fuse.
