I am in shock at all the BS wiring done on my bus.



When I got the bus I just ran extension cords to the back and ran all the major controls through those, so this week since I was replacing the drivers seat it was time to work on the wiring



There have been so many weird unnecessary changes it drives me crazy, after awhile I just pulled all the haywire bypasses, 'til I was down to the original wiring.  Guess what, once I had fixed 1 bad ground wire almost everything was working again, certainly all the main engine controls.  Even the relay I thought was bad is working.

The bad ground was caused by a lousy splice...BTW remember to seal your splices otherwise they corrode and fail years later and some lousy SOB has to spend hours chasing wires etc...to find your sloppy work. 
  So again I ask WHY?Huh?


For those that like work in progress pics this is my old drivers seat.



and this is my almost new seat, pulled it from a wrecked transit, wasn't worn out like all the other transit seats, has 3 lumbar air controls as well.



temporarily installed, seems low but that's because it's not aired up.

lol...I feel your pain. I've asked myself that same question on just about everything I buy from houses to cars and have come to the conclusion that most people think with their wallets and not their brains or their just plain lazy. Here's a pic of one thing I found while converting my previous coach. It was a 4104 also.

Zub,

Another thing to watch for is corroded lugs and nuts on the terminals and corroded wire from lugs for about the first inch or so of the wire. There is usually enough extra wire to cut out the corrosion. My 4104 had bunches of these.

I replaced a bunch of lugs, cleaned all the old ones and replaced the nuts with clean brass ones, then put a drop of Corrosion-X on each one.

Yankee,

This is an approved busnut repair/mod!! Some BN have used rubber hose and hose clamps, yours is a much stronger version with those cable clamps!!

Regardless of any poor repairs done by previous owners, the wiring shown in the first photo surely needs completely ripping out and completely renewing anyway - chasing individual bad grounds and connections seems a little pointless in 50-year-old wiring like that, other than just as a temporary measure before you get around to dealing with the whole lot properly.

Just my opinion, but I'm sure I couldn't contemplate running power through a rat's nest such as that for any length of time, and certainly not using the vehicle on the road with the wiring in that state.

Oh Jeremy, you have now gone from a rat's nest to a wasps nest.   There are more than a few of us using and driving buses with the original wiring intact.  When I first got my bus I presumed that I would need to re wire everything, but as I get deeper into it, much of the original wiring is still intact, not crumbling (I have a northern bus so lessheat degradation) and the combo rubber sheathing with cloth overlay is standing up nicely.  So after all I will be using the original wiring, and once I have it sorted, it will be safe and reliable.

Buying any bus that has already been converted will have it's head scratching moments. Then top it off by the fact that many of the busses are older than the owners (eg.  insert name here  Cheesy) and you're gonna find a lot of strange things especially when it comes to wiring. Everytime I get deeper into some of those issues I go WTF! My latest was 16 gauge wire to the Suburban heater. It pulls 8.5 amps according to the book and had melted the wires together. I was surprised when I found out it had never even burned the paint off the heating unit yet.

Easy for you to say Jeremy, with an '87. If you had a '54 you might have an entirely different perspective!!

Ripping all the wiring out and replacing it is a monumental job, life is too short for that and the chances of screwing it up are great. Just running all that wire 35'+ would be a nightmare. No thanks.

That panel looked like a rat's nest even when new!! There is another smaller one almost like it at the rear!!

Neat is nice but looks really don't count in electricity, who is going to see it? The little electrons don't know the difference and don't care!

I'm with Zub on this one.

Jeremy, there's a reason that most from the old sod run screaming to the airport for home once they have been introduced to the methods of engagement here in the Transportation industry in North America...

Whether it is our wiring or our disinterest in embracing disc brakes on the heavy stuff....

oh well.

happy coaching!

I suspect an older bus is easier to rewire than a newer bus.  My bus is a 1995 and the wiring bundle front to rear is about as big around as my wrist if not bigger!  The older buses don't need near so many wires to make them run.

Well, I guess I'm out-voted...but not convinced. And I suspect the electrons do care, and haven't been convinced either.

Zub,

The best thing about having a "PO" is that if someone says "Who did that"

It was the PO of course...... Wink

That's a good point Cliff.  Maybe it almost makes up for all the work, which to be fair, there has been a lot of maintenance done on this bus over the years, in fact the mechanicals are all in good fettle, I guess the mythical PO of this bus just couldn't handle all the do garn new fangled wiring on this modern (1953) bus.
