OK E(I), I'm ready to take my journeyman's exam.


nodisbeliefconfuse  The horn on my Fairlane that I so carefully and creatively installed quit working so this morning I started trouble shooting.  First I tried jumping across the switch button terminals and got nothing hmmm ain't the switch so just to make sure I took it off and tested the continuity when pressed GOOD - it still ain't the switch.  Now I must admit that it took me a few minutes to remember that I had the switch in the ground lead and not the positive lead.  After that I started checking the continuity of each wire and when I would take the ground wire directly to the battery ground I heard a clicking at the horn relay.  Hmmm bad relay maybe? needs further testing.  Took the horn off and tested it directly at the battery bypassing the relay - - - - WOKE UP THE NEIGHBORHOOD  Horn works ain't the horn.  Then I put the horn back in place and started testing continuity on all circuits in and out.  WOO HOO I found that I wasn't getting a ground at the horn mounting bolt connection.  Took it off, drilled an appropriate hole and reinstalled it with a good hex head metal lag screw.  BEEEEEEEEEEEEEEEEEEEEEEPPPPPPPPPPPPP  Houston we have a connection !

The neighbors probably thought I was imitating Tarzan when I started struting around pounding my chest but they had just woke up and were probably still a little dazed

So when is my Exam?

Check with the local JATC (Joint Apprentice Training Center) office, see if they give credit for experience. Sounds like you might be on the right track.

Yanno, grounds are the number one problem in automotive wiring; they, or the lack of them, cause more headaches, damage, and premature disposal of perfectly good automobiles than any other automotive electrical problem. Running a close second is attention to connection integrity - dirty, not properly prepared initially (didn't clean all the paint off), corroded, or not fastened right or well. The third, in my estimation, is improper wire size and/or type.

Yanno, now that I think of it, I can remember my Dad's classic comment when any of us went to him with a wiring problem was - - - "Son, have you checked to see if you have a good ground?" - - he didn't have a high school education but he could fix anything mechanical and most of things that I tore up. hahahahaha

Drum rolllllllllll. Hijack time.

First of all, Em 2, congratulation on a job well done.

Now - automotive electricals have been and continue to not be a strong point with me. The older cars - one wire took care of the device and not too bad. Now - OMGollee.

Yesterday and today I have undertaken replacing the candle imitating headlights on my truck as well as my wife's Fusion. The truck is fairly easy once you get to the connectors/sockets. Pull four bolts and release 5 tabs and remove the grille and that is much easier then it sounds. Then pull four more bolts to remove each light assembly. Then it's just R&R and reassemble. Thirty minutes including finding the right tools. I also had to replace a light socket ($41 at a 50% discount for an original part) that I would guess that when the original owner encountered Bambi, it broke and the body shop screwed up. Now the 2012 Fusion LHS - not too bad. Just remove the air cleaner box assembly, the MAF wiring and a splash shield. The RHS - so far, remove the windshield wash bottle filler hose, loosen an a/c lne then snake a mid size hand in there and the high beam bulb is done. The low beam bulb - remove the RF wheel, the inner fender panel and I think the socket will be in sight - but that's for an hour or so from now after lunch and a cuppa joe (adult bev later for celebration)

Amendment 1

It wasn't that easy as noted above as there was virtually no free play in the wires. I ended up removing the puke tank under the hood and was able to pop the bulb loose then slide the new one in place. Thankfully my hands aren't huge (XL gloves fit just right) so I could just barely fit in there. It's back together and everything seems to work.biggrinbiggrin
