I have an Auto Meter electrical oil pressure guage and I mounted the sender
unit just like this C-Speed pic

but it is not getting a good enough ground?
how do I ground the sender? It has no place to hook up a wire?

 

I was in the same boat when I installed my setup today. I don't know if it will last but I stripped off a few inches of insulation on a 12 gauge wire and wrapped it around the T-fitting. I tried to solder it on with a propane torch but couldn't get a good solder connection so I made sure it was wrapped tightly, wire tied it in place, and used liquid electrical tape to cover the wire so it wouldn't corrode. We'll see if it lasts. I had the same thought that there should be a grounding terminal on the sender so we don't have to rig something like I did.

 

solder one on to the fitting or the casing... my ghetto *** way of doing it was to take an eyelet... and drill it out until it almost fit over the theads of the oil line.. and then screwed the sender onto the eyelet connector...
My guage seems to work fine.

---------wire----= (O)

eyelet connnector
screw the input of the pressure sender through the eyelet connecter... then attach the sender to the line.
.. you could try this.. take the T off... and try to solder or weld a "connecter" like a piece of wire to it to connect a ground wire to that

or make a metal bracket that connects the metal tee to the chassis directly

I have the same gauge and i didn't have to ground the sender. Mine works fine with the single wire coming out of the top of the sender.

 

Is it set up like the pic in the link?

 

Get a hose clamp. Clamp it around the sender and sandwich a stripped piece of 12AWG or similar stranded wire. That is the best way I have come up with to ground these things and not have them vibrate off. Try and keep the ground wire under 18 inches long.

Hope that helps

Thanks N24RE!

 

Sure thing bro...it works like a champ done that way. I've been all through this OIL stuff with these Hondas...check my sig for links to my oil cooler install...that was a pain

Cheers'

 

that sounds like the best idea... thanks

 

I just reinstalled a New sending unit from autometer (killed the first one) on my G2 non v-tec engine I didn't hook up the factory sending unit it DOES NOT throw a check engine light or turn on the oil light on the dash. You should not need to add a ground wire to the sending unit if you screw it into the block, but will need one if you need to do the setup like the pic showed (v-tec engine), because the braided lines are rubber inside and we all know rubber is a insulator not a conductor.

 

if the sender is screwed into the block.. or is grounded somehow by the oil line.. it is grounded by that... sometimes however it needs a better ground
