If the electrical power on the inside is off, but the top raised, your Master Switch is probably still in the "Raise/Lower" position. You can download a manual for the 1997 towlite in the first post in this thread:
https://www.hilotrailerforum.com/f49...-towlite-1728/ I know this is not your model, but the manuals are fairly "generic" and things did not change much from year to year. I think that manual will cover your model almost perfectly.
Go to Post #3 in this thread:
https://www.hilotrailerforum.com/f49...-youtube-1233/ for a video manual for our trailers. The videos will answer most of your questions and should cover everything you need to know.
In the manual you can download, page 24 shows the adjustment points for the lifting cables if a corner is low. The top should raise until the bulb seal makes good contact with the lip on the lower half.
