Electricals April

Norman Julian 8 Apr
I was talking to a bus enthusiast who knows a lot more than me about the electricals on these old buses and the work I did yesterday on the rear door was wrong.
He also told me about other things that I haven't got around to and I completed them today.
I took all the old wiring out of the bus because some of it was burnt out anyway plus it was over 60 years old and there were bits and pieces added along the way, so I decided to replace the wiring with new stuff, hence I needed some guidance.
There are a lot of traps for the uninitiated.

Well you’re dead right there. After all you’ve done, a wiring fire is the last thing you need.
Gregor Neil Robertson
And install wire/cable fit for the amperage.
When I start a project, very first thing I put in is a battery cut-out switch in an easily accessible place firmly mounted beside the driver.
And every component protected by a fuse of its own. I try to keep...See more

Here is a question for some smart person.
Because I'm replaceing the headlight globes in the Leyland decker they have to be 12 volt.
I have never replaced a modern globe and normally if you do they go in the holder one way so when they sit in the headlight it is in the right position.
Now because these old buses dont have high beam and just low I am wiring it up as such. Now here comes the question. The element at the front surrounded by the silver or chrome reflector is the low beam according to what I was told.
Now where and how does this globe sit in position in the housing.
Does the chrome reflector sit above or below the element.
If its wrong I'd imagine the light shinning ahead on the road being either up or down.

It faces up so as to reflect down on the road.
So middle terminal ( for low beam ) is horizontal.
Norman Julian
So the element uses the reflector as an umbrella
Scott Wilson
No.
Under sheild to aim light up into top half of reflector so it aims down on the road on low beam.
Norman Julian
Yeah!
The reflector is above the element so as to shine down
Scott Wilson
Norman Julian No.
The other way.
Norman Julian
Doesn't by having the reflector under the element have the light shinning upwards
Scott Wilson
Norman Julian
OK
Scott Wilson
Norman Julian
To the top so light goes down onto road.
Norman Julian
OK now I understand.
Never ever touched a replacement element before.
I learnt something else today.
One of these globes has been made on an angle.
No wonder you see doggy lights on modern cars sometimes.
The base plate on one of these has been soldered on a slight angle so it isnt at 90 degrees.
Norman Julian
Thanks Scott Wilson!
You are a gentleman and a scholar.

Norman Julian i drove a truck once with the H4 lights mounted upside down, no wonder i couldnt see where i was going until i changed it
Scott Wilson
So the pin holes need to be drilled next to the 2 vertical terminals
Norman Julian
The holes are drilled and you can rotate the reflector anyway if you need to.
Scott Wilson
Just easier to have holes in a common position at 9 an 3 o'clock.
Norman Julian
I'm not proud.
If I don't ask the question and I don't know then I wont learn anything.
It seemed like a common thing to know I guess.

Bunnings might have the Globes for you Norm or a Sparky will have to order them

1635 should have the brightest and therefore most useful headlights ever fitted to a half cab Sydney decker. ��
Norman Julian
I have black paper over the top part of the lense now so it isn't as bright.
Norman Julian
Didn't they do that during the war!
LOL
