Thanks to many for the warm welcome as a newbie- I really appreciate it!!
Will be certain to also lend my experience in brakes/ interior wood as a pay it forward mind set.
Hope there is an electrical guru that may have some insight.
Here is my situation in short:
1990 limited triple axle, fully operational, fulltimers, boon-docking and solar equipped.
All lights were operational until a month or so ago.
Now my marker, or running lights are out.
Here is mt current trace back for root cause- any insight on my oversight and insight as to where I might go from here is so much appreciated:
1. hooked up my TV to another A/S , their running lights worked fine, did not blow my TV fuse, indicating it is an issue with my A/S, not my TV.
2. Took apart my umbilical cord, to be on the safe side, wired up a brand new umbilical cord, tested it on another TV- it blew that TV's fuse as well. I also tested my TV on other A/S and again all is well. My TV only blows the 15A trailer/parking light fuse in my TV when plugged into MY A/S. so....deductive reasoning- there is a shore someplace in my A/S but where? or where to start looking??>?
3. I had replaced ALL my running lights with LEDs, rear light/signal cluster included. All lights worked fine (including running lights) for the past year, I literally woke up one morning and no running lights.
3.1 I DID take off each running light and examining for a short, confirmed the heat shrink in place and ground was in place. I also did the same for the rear tail light clusters.
What I do have ( on the positive side ) is the following
OPERATIONAL left and right hand blinkers, operational brake lights and operational 4ways. it is just the "running lights" when I turn on the TV head lights that are non-operative.
As a follow up I did place a 15A fuse into the top two female slots on the A/S umbilical cord (an old school method to check your running lights) and the fuse will blow, whereas prior to this non-op issue, it would just light up all running lights.
Now, all kidding aside- not really- but we did drive near Area 51 !!!
I am at a real loss here. As we are retired, we normally do not drive in the dark, however at times need them due to fog or rain. At this point we are using our 4way lights as indicators to abide by the law as well as be visible
34' is a LOT of silver in the fog!!!
Thank you to one and all for any help , insight or direction you may have into this mystery! In closing, this seriously was a one day they worked, the next day they were non-op no storms or anything else erratic.
Safe travels to all-
