I cant get my autometer electrical oil pressure guage to work. I think that I need to ground the body of the sender that autometer gives to you but I cant figure it out. If any of you guys have a pic of how you grounded it then that would be great.
drew-

 

I used a hose clamp to mount the sender to the fire wall and attached a wire to the hose clamp.
Simple easy cheap.

 

could you get a pic of it for me?
that would be great if you could

 

Sorry for the size.


Here you can see it between the booster and the prop valve.
It's a little hard to see the wire coming out of the left side of
the hose clamp but its there.
You can ground any part of the sender body.

Yeah, If you already have the sending unit installed all you have to do is slip a hose clamp over the cylinder part (housing)of the sending unit and stick a ground wire in between the hose clamp and sending unit. Tighten the clamp and then attach the other end of the wire to the chassis. If you want a quick way to test it. Just use a wire with an alligator clip at both ends attach one end to the S/U's housing and the other to the chassis and test it to make sure it's working.

 

Ok I think I get it, I will try it tonight. what part of the body did you ground it to?

 

You can attach the wire to any bolt which attaches to the chassis as long as it has a good ground. I installed this gauge in my 240 when I did the SR swap. I just attached it to an abs brain bolt. In the honda it looks like you could use one of the bolts which holds the fuel filter to the fire wall. But I'm going by what I see in the pic rolow posted. I don't know where you installed you sending unit.

 

Ok, I installed the clamp and ground thingy. The guage is doing the same thing that it has been doing. right when I flip the key to on it goes past 100psi and hits the side of the guage cuz it can go any further. Is the power supply that I hooked it up to way to powerful?
thanks for the help so far this thing is a pain

 

sounds like your signal wire is directly grounded... If you ground the signal wire right to the chassis the needle will move all the way. I got a vdo electric oil gauge and I was messing with it to see how it would work and I messed around with the wires to see what happened and thats how I figured it out.

 

hmmm.... I will have to check if it is grounded. I used the ignition on the fuse box for power. Do you think that is to much juice?

 

I wouldn't think so, I mean 12 volts is 12 volts, and the amps shouldn't really affect anything.

 

Alright I switched the the ground and signal wire and it shot all the way over passed 100 psi like you said. So I think some how the ground and sender wire are touching which is causing the send to ground. Is that how it works?

 

Ok, are you sure you have the signal wire,ground for the light in the gauge and power all hooked up correctly at the gauge itself. Make sure you look at the instructions manual and are using the instructions for the oil pressure gauge. At the sending unit. The connection for the send unit wire. Did you leave out the spacer which keeps the sending unit wire and nut from coming into contact with the housing of the sending unit? I seem to remember mine having something to stop the wire from touching the housing when you tighten it down. Someone correct me if I wrong here. This may be causing your problem.

 

I know I have them hooked up correctly but I dont think I have the thing that keeps the wire from touching the body of the sending unit. I will double check.

 

oh so your sending wire could be touching the body of the sending unit? That makes sense cause you have to ground the sending unit someway and most people do what you did and take a hose clamp and wire to ground it. The way it's designed is to screw in a hole in your block and it grounds itself that way. One reason I like my vdo sender is that for my signal wire I can use a female spade connector and just clip it on.
