Electrical out to 3 lite fixtures

Hi,
I've lost 12volt power to 3 lites near my bathroom and the small fan in bathrm vent. I was attempting to install a new ventline roof vent due to a small crack. The plastic dome was very brittle after 10 years in the sun. I ordered all new parts from Camping World and installed them. When hooking up the small fan in the bathrm vent there was a small spark when disconnecting the old fan wiring. The blue positive wire touched the aluminum frame. Now with everything reconnected and installed I have no power to the fan and 3 lites in the bathrm. I checked fuse panel and all test good. There are 4 auto resetting breakers near my battery box on trailer A-frame. They all test good. All other lites and appliances are working.
I notice a lot of slack in the blue and white wires coming from trailer ceiling area. Maybe I accidently pulled the blue one loose.
Anyone got any ideas?

from the "spark" I suspect you shorted the 12V to ground and did pop one of the 12V fuses.

Check the fuses again. Often the wire does have a lot of slack. However, the slack should eventually end, BEFORE you end up with both ends of the wire in your hand!!

if that is the case......well...... your job may end up bigger than you planned.
