What are these?

**Chris078** · 18th March 2016, 11:42 AM

I'm starting to put the dash back in. Wondering what these are.
They look like fuse holders, and inside them looks like a glass fuse except that instead of a little wire inside the glass, it looks like braided material of some sort.
One of them is also getting quite hot. Almost too hot to grab, which I don't like as I just spent two weeks fixing up the wiring behind the fuse box due to a short.

Next thing is that my wiper motor has decided to stop working properly.
It was making a bit of a 'clacking' sound so I took it out and cleaned off the old grease and put some new stuff on.
Naturally I ran into issues. The ground strap that runs to the motor body broke. I made a new one with wire - would that create an issue?

The motor works fine with no blades attached, and with both attached but folded out (not touching the windscreen) It will also work when one blade is down. put both on the windscreen and it will move them maybe 6 inches and then stop. Have to lift one off the windscreen so it can complete the cycle.

Any ideas before I get sick of this thing and call a scrapper? Every time I go to fix something, I end up finding something else or making it worse. I've spent more on this car than what I paid for it, without any major mechanical stuff. just lots of little things. Getting a little tired of it.

<edit more info>
2 things I've just noticed.
1. when the wiper motor is on the Amp meter drops around 1 Amp per cycle. eg 13-12-13-12

2. before (when I noticed the little white fuse holder being hot)I had the charger on . I just flicked the wipers
back on for a minute and it did not head up , only difference is the charger was not on.
I've packed up for today, but I'll test tomorrow with the charger on and see if it heats up again.

Semi fixed the wiper motor. The nut that you take off to remove the ground strap is attached to a bolt that runs right through the motor. I did not realize this and it was loose at the other end so was not grounding properly.

Still a little slow and clunking like crazy.
Touched that little white fuse thing after running the wiper motor - too hot to touch! something quite wrong there.

Ur wiper motor may be poleing out. Caused by worn bushes or brushes may be worn or one brush is not making good contact with the armature causing lots of current draw which would cause the fuse and wiring to overheat and poss catch fire. Wiper motors are fairly cheap. A wiring fire will cost u dearly.

Yeah. I still don't know exactly what caused the last electrical issue. All I know is that the wire that runs from the stop check relay up to the dimmer switch burnt out and did not throw the fuse when it did it.
I was so very, very lucky that it didn't burn down when that happened.
That's why I really want to know what the heck those little white things are.

Correction on them as well. There is no glass. It's just a metal braid that looks very similar to a ground strap.

A fuse will only blow if theres a short circuit, not an overheated wire.

Yes, they are fuse holders and they look like they could be slow blow fuses. Are there any numbers/letters on the end caps?

This was going to be my guess too. Someone could have had nuisance fuse blowing from the dodgy wiper motor and stuck in a slow blow fuse to get around it.

The fuse is there to protect the cable. Its a poorly designed circuit if the cable is getting hot (outside of its operating temperature) and the fuse ins't blowing.

high frequency ultra slow blow fuses...

pretty sure they shouldnt be in a landrover.

if they were rated at 10A for where they are supposed to be used (and without going to my books for this stuff so therefore at a guess) in 12V DC land Id expect the instant blow current to be in the order of 50-60 amps

Late finish at work last night so I'm only just getting started. It's also muggy as hell here in Brisbane today, so I don't think I'll be getting much done in the garage today.

So, do you know if these fuses (well, the holders anyway) are meant to be there or if someone has added them?
They look very factory fitted to me. colour coded wiring etc.
I don't recall seeing any marking on the fuse itself yesterday.
I'm about to go and pull them to try and work out what they are actually the fuses for, as well as test out having the charger on and seeing if that heats them up at all.
