I've done a search with no luck.
When you have a sensor such as a water temp sender in an alloy pipe joiner and you need to earth it what have you done? I'm sure LB members will
have some ingenious solutions. So far i have a washer under the sensor and I'm trying to attach a spade terminal! what have you done?
PS. The washer is flat against the sensor housing, so screwing a small screw into the washer will not work. Ideas?
TIA
Ben
Instead of spade terminal, why not use a ring terminal?
Strip a couple inches of insulation from some wire, form the bare wire into a loop the size
of the required washer and the fully solder the loop. Fit to sensor and it'll seal like a copper
washer with a nice wire to fut a spade on.
I've tried ring terminals Ben but they all seem to be too small.
NigeEss - thanks that sounds worth a try.

Yeah. Looks great but unfortunately I already have one of those without the earth screw.
No doubt this is a stupid question, but i didn't think ali was a good conductor. I thought you needed steel to conduct well. As in connected
directly to the sensor itself. I guess not from that link.

Whilst ally is not high on the list of electrical conductivity it does conduct well enough for automotive applications.
If it didn't, then car manufacturers would not bolt earths to heads, gearboxes etc, all of which have sensors screwed
into them.
Ah that makes sense. One less issues to deal with! Thanks for your help.
its a bit crude but shove a bit of wire between the ali tube and hose and wang the hose clip up as tight as you can. or just wrap the wire round the
ali pipe and put a hose clip over the top of it.
the proper solution would be to replace the sender for a 2 pin version.

Make a tab washer from sheet with the tab the same size as a male spade.

Because my solution is "Locost"
That does look mighty pretty though

When it comes to the engine, reliability is more important than saving a few pounds, do the job right and you will not be breaking down 100miles from home

Is that effectively earthing through the coolant? If it's sat in the middle of a rubber hose I can't see how else it has conductivity with the block.
It has a earthing screw so you can attach an earth wire properly via a ring terminal. Whearthing tab from a steel wire armoured cable gland?? Any local electricians might be able to help you.

Jamming bits of wire under the sensor is not "Locost", it's simply a bodge. However, if you were feeling keen you could fabricate a washer with an integrated spade terminal out of e.g. copper.
