Anyone got experience with this type of fuse?

I changed the whole assembly about 6 months ago after I noticed the housing had cracked.

Seems to have happened again in the new one I’ve put in.

Joint must run too hot. Fuse is ok, just housing melting.

Any experience/recommendations? I might try a different fuse type or else take into an auto elec as should be a simple fix.

Cheers

That type inline fuse is pretty ordinary at the best of times, but especially if it runs a close to it's maximum rating. Are there any accessories on that circuit?

I installed these on a 30 amp feed line to my intercooler pump - they got so hot the housing melted and deformed but the fuse stayed intact.https://www.ebay.com.au/itm/362821714325. I have since moved to this style and all good so far, wire sizes are correct and so are the connections, https://www.ebay.com.au/itm/ANS-40-A...Cclp%3A2334524

Thanks mate.

Nah I’ve got a very simple set up.

It’s a new battery, had for a yr or so and alternator voltage has always been strong.

Light bar on front and that’s all.

Air con.

Although there maybe some loose currents as the wiring in the vehicle is a bit of a mess as was an auto converted to a manual and previous owner looks like they had a few accessories. Which I don’t run. I removed everything off the battery I was not gonna use when I bought it. I have seen a few wires which are covered with tape and not connected to anything. Haven’t traced them all back to remove yet.

My plan is to keep the wiring as simple as possible so I don’t have reliability issues. I just need the thing to run reliably for camping not using as a tourer yet.

Might just be the fuse type and running current. So should I try a different fuse type first ya reckon?

My dream is to label all fuse and wiring in the vehicle and ensure I know I have a replacement fuse etc for any issue. Might use this opportunity to do that...

Yeah, these handle 30amps constant, no problem at all

Ended up being the headlight circuit I think, runs through this 12V, 30A relay in the engine bay relay box - blue and red wire. From there looks like the wires from the relay run to front lights.

So I changed the fuse and will watch it.

Thanks
