Cool..
The best bet is to just get to the K38. You can look for voltage at pin #1 once you are there and that will verify Ign sw feed to that point,,,easier than taking out ign sw. Same deal as with NSS/#50 12v. lamp test.. with Ign.Sw in Start position...if you get power in K38, but none out ... you know that is the problem

The jumper is just a faster way b/c you don't have to do voltage testings ..but you can , if you like ..either way.

I own a Home in the Ocala area and will be making it full time . Might see you down there..
Good Luck and let us know what the fault outcome was.....
