Trailer brakes and wiring

[Kappy]

Hi all.

I recently purchase a 4.5 ton tandem axle trailer from a friend, that I knew would need some work and renovation to suit my needs.

Why?? cos the price was right and I need the size to carry a small car and my harley plus stuff.

Things are progressing with my trailer, since my little hiccup I have replaced bearings on the port side seeing as I fitted new hubs/drums to the starboard side, so new bearings all round. While I was at it decided to replace all the brake shoes.

Now I'm tackling the wiring that seems to be all there, but not sure if the electric trailer brakes work (think the brakes shoes were worn out when I towed it down from Port Hedland) although all the wiring seems to be there.

When the trailer was attached to the bus the brake lights illuminated when I applied the brake controller inside the bus.(plus the reversing lights )

Anyway on the draw-bar I've noticed what remains of a box with a series of fuses that seem to be linked to the trailer lights. Id like to tidy this up for obvious reason of safety etc. Iv'e ggogled to no avail and all the trailer/ braking wiring diagrams haven't revealed anything similar.

Then some disconnected wires some of which appear to linked to internal 12/24 volt lighting and I figure may also be linked to the electric brake/ break away system.

Has anyone any experience in this area or have seen this set up before and maybe offer some assistance.

Electrical stuff not my forte or do I take a punt on an auto electrician to sort it out.

Pic of other wiring as I couldn't figrue out out how to place more than 3 pic's in the one post.

If you have a multimeter or test lamp, just go over every wire to see where it goes and if it is unbroken. I'm a dummy with electronics, but found using a multimeter means most wiring jobs on trailers can be done pretty easy.

Just bought a dual cab tipper for my farm, being unregistered, had to go over the pits and was able to work out all the non working wiring, except for the exhaust brake. Luckily or local auto elect has a couple of flat tray Mitsubishi's and knew what to look for, cost me $90 and he was done in a couple hours. Turns out the exhaust brake has multiple switches and fuses connected to the clutch, accelerator and switch, so would never have got it fixed myself. Do as much as you can so you familiarise yourself with the wiring and what your can't do, go to an auto elect. The more you know about your rig, the easier it is if on the road and something goes wrong. I'm in the process of rebuilding a trailer to carry our band gear and will do all the wiring myself, including brakes

Like the look of your trailer, just what our band needs, one that size so we can carry everything, including bikes and centrifuge. The one I'm working on is 8x5, which in reality is not really big enough for our needs.

There is something missing, I think the loose wires are to do with the break away system plus battery etc.

My trailer is 6m x 2.4 x 2.4 internal and is about 7.5 metres long.

Surprisingly only impacted on the bus fuel economy by about .25 - .3 kilometres per litre.

I have no idea what the bands mean, they were already on it.

Kappy,

Normally. I'd be suggesting doing it yourself. But this time, I reckon get a good auto sparky to fix it.

The trailer is heavy and will probably need a break-away system fitted, plus all the wiring fixed up properly to make sure the brakes work as expected, plus the lights and probably as well, a feed from the bus.

DOn't forget, it might need a RWC to get it registered in your name. The sparky will (should) make sure it passes first time reducing extra costs.

[Kappy]

Already registered, so no problem there, but having lost two wheels bringing her home, I/m inclined to make everything right.

That is re engineered split rims, brand new 12 ply Tyres, new hubs for damaged ones, new bearings and new brake shoes.

Then fitting shockies to enhance towing.

This is a pretty big trailer and wish to reduce dramas.

So maybe a sparky is the go, bus wiring may be iffy

Hi,

Looking for some advice regarding trailer wiring.

I have this fuse box that needs attention

Trailer wiring fuses.jpg

I've looked high and low and can't find one, can anyone direct me,please?

I have a TEKONSHA style brake controller, that I have not idea if it works, when the trailer plug is connected and I apply the manual brake The trailer reverse lights illuminated. Mmm

I stumbled across a this on ebay, http://www.ebay.com.au/itm/REDARC-TOW-P ... SwTA9X33g0 has anyone any experience with style, looks quite simple.

BTW I took the trailer out for a run yesterday with new tyresm rims, bearings and brake shoes. New tyres made a differrnce to handling, next is install of shockies to trailer.

Cheers

Kappy are you looking to replace the fuse box?
Is the trailer wired @24v or 12v (and what is the bus wired?)

[Kappy]

Mmmm

Pretty sure trailer is 12V, bus is mainly 24V although there is Red Arc 12 V converter in engine bay linked to trailer plug.

Yes wanna replace fuse box as current one is damaged and open to elements, can't seem to google replacement.

Cheers
