Too many wires !!!

The engine’s brakes had not been working properly since I bought the bus and I didn’t have to use them anyway as it was so flat in South Australia and the Northern Territory. This is going to be a job the will take some time as I will have to trace the wiring loom from one end of the coach to the other. The main problem is info, I’ve have most of the manuals that I need to be able to fix most things but finding out the colour codes for the wires is not so easy as nothing matches what is on the drawings that I have. I have searched the internet for more wiring diagram but to no avail and I can’t seem to find anything that looks even remotely the same.

So with a multimeter in hand, I thought the best place was to start with power to the switch, then start tracing the wires from there. Well the good thing is I’ve got 24v at the switch, the bad news is now people have been here before me modifying the wiring loom.

The main board outside, below the driver’s seat.

Looks nice and tidy in here, but somewhere in there may be the problem of the J brakes.

Mmmmm some one has been here before me, lot’s of cut wires.

Doesn’t look so nice now as there are lots of wires that have been cut or have never been used. The fuse holders that have been burnt out (3 of them) after being moved, as well as modifications over the years to fix or been up graded.

This job just got bigger

So now its time to trace all the wires not being used and tagging both ends of them, this will help find where they go. After making a 9v system to clip onto the wires its just a matter of finding the other ends of the loom.

Now the fun begins, just have to find out where they are going.

Sub board down the back of the coach in the battery bay.

Somewhere in here is the wires for the J breaks that are not working.

Look more wires behind the dash. Ahhhhhh!

Some switches work and some will not be needed any more.

The J breaks will have to wait

I’ve just been told that I can move into the equestrian shed so the wiring will have to wait for now, as the main problem is the roof leak under the top decking. This started after we move up to Toowoomba, it may be a small pop rivet as it’s not a big leak more like some capillary action going on.
