Excuses in order:
1)When we camp I use the parking brake.
When I store a vehicle for a long period of time I leave the brake off so as to no lock parking brake to the drum or disk.
2)Once I read the post about the parking brake I went to the yard and put it on.
Still could not get the slide to work.
Went and checked the fuses again. This time the right most purple line had power. However when I moved the fuse I could see I was getting intermittent connection to power. I took the fuse out and squeezed the connector blades together and reinserted the fuse. This time power stayed on.
Retried the slide and it worked.
Thank you both for giving me the information I needed.
When I bring the MH home I will solder a separate fuse block to the current fuse holder that way I have a secure connection with a removable fuse.
