I'd look for a black box near the battery... follow the hot lead!

Morray, I'm coming to the conclusion that they are simply individual wire cores in the harness from the starter motor to the fuse box rather than an individual component. Certainly there are seven yellow cores of varying gauge crimped into a big tag on the starter motor and disappearing into the 'cab harness' and there seem to be seven of these 'Fuse Links'

Later Edit: (oops - it seems that there are 9 'Fuse Links' ! )

Time for the hydraulic filter change. This had been delayed as the new gasket that seals the access port for the filter had been supplied incorrectly. They sent the inspection port gasket by mistake. Replacement arrived by today's post so onward and upwards . .

Clean up round the port, unscrew the bolts, scrape off the old rubber gasket, remove filter, replace with new - what could be simpler. While the oil level was low I replaced the totally opaque old level gauge and fitted a new one.

There is a tank breather in the filling cap that needs replacing, but in fact I replaced the entire cap with one with a locking facility.

Topped up the 32 weight hydraulic oil to the mark - job's a good 'un

(except that that was the last of my 32 weight hydraulic oil so an order placed for a further two 20 litre drums)

Yesterday I had another crack at the wiring mystery - this 'fuse link 7' business. I'm more and more convinced that the fuse links have been done away with and are merely cores in the wiring harness.

Also, thinking as the faulty cab light AND the faulty radio were both supplied by this link then it must itself be faulty. WRONG :bang:

I took the radio out of the console and powered it up from a bench power supply, and it IS genuinely faulty. Then just to confirm it I proved a connection was getting to it's power connector using the tone tracer.

So it now turns out the cab light isn't working possibly due to a single failed core or connection splice on cable 303 in the wiring loom. This of course is hidden behind the head lining and trim but I may be able to get a bit of access where the clock mounts.

I'd thought that I could use my endoscope camera BUT plugging it all together it turns out that the 'ap' no longer works with the version 15.1 of IOS that recently upgraded on my phone and the Chinese supplier hasn't written an upgraded version :bang: Don't you hate technology.

So - now I'd like to get the radio working - far from essential but nice to have. It's a Clarion Finish Line 540 single DIN sized with an ISO connector for power and audio, mounted in a cage for it to slide in.

Easiest option is to find something physically compatible and just swap it out but I'm not sure how 'standard' the standards are in terms of the placing of aerial and ISO sockets - certainly the few I've seen on eBay seem to have the same sockets but in differing places.

So . . any suggestions welcome as always.

I've spent DAYS trying to find the 'Boom Lock Master Cylinder Reservoir'. The Boom Lock is a tri-angular plate with holes in it that hinges on the kingpost, and when lowered goes round a cast knob on the boom, preventing it drooping when in transit.

The service book is little help with location other than that fore and aft it's in line with the rear axle. As it's on the 50 hour service check interval I'd expected it to be somewhere easily accessible. I've poked and prodded into all the nooks and crannies of the cab trim expecting an access hole somewhere but today I gave up that approach, and got out the crawler board and slid underneath. No problem getting on the board, it's getting up afterwards that's the issue :bugeye:

Well guess what I found ! Far from being on the right hand side of the machine near the lever and where the manual implies it is, it's mounted on the extreme left hand side of the axle, with the filler cap practically touching the floor and virtually impossible to get at to unscrew or fill. Still I've found it !

Oh and I found a chap under there muttering about having lost a reservoir :lol:
