Absolutely take it down. You may have gotten lucky/unlucky. If that lower cylinder is the only one. I never read where it went totally under. If not perhaps the wiring isn't going to need replacing.
I can't decide if I am cheering you up or full on kicking you in the gnutz. Sorry about your luck.
Remembering back to the initial repair, you couldn't get to the repair from the inside of the hull, correct?
