oil gauges issue

[esty]

VDO oil pressure gauge....connected supplied wire from "S" to sensor..."+" to a switched, hot lead and "-" to ground..

when i turn the ignition on and or start the car the gauge pegs out and stays that way...i tried reversing the + and - wires because somewhere in my mind, i recall reading that might correct it....to no avail

any ideas?

According to my VDO installation instructions,("S" on your gauge- "G" in the schematic) you've done it correctly. Maybe someone else can shed some light. (or how about the pressure sensor?)

Do you have the dual oil pressure sensor? The one with both an idiot light and gauge connection? If so you have the S on the wrong terminal.

no sir...here's the one i have...i have a new one that i got with the gauge...i'll try it another day...my old one could have gone south on me

That's the wrong sender. Get the one designed to be used with a guage(with matching pressures for the guage). The one you pictured is for an idiot light.

thanks chris...i have one like you pictured but assumed because one wire goes to sender, i should use the sender with just one spade...

the one you pictured...why 2 terminals...one for pressure gauge...one for idiot light, as mentioned above?..

thanks for the pic

This looks more like a oil temp sender.

Bingo!

who knows what size and pitch of the threads on the single spade style, original oil sender...the threaded end of the sender with 2 terminals is smaller and i can't find a bushing that fits the hole the sender screws into

...this is the proper size

...this one's smaller and the one i need a bushing for

Someone may know for sure but I think it is a M12 on the OE sender.

Your dual post sender is probably a M10 but you should check to make sure. Take a spare M12 stud/M10 nut and see if they fit.

Make sure the ohm range of sender matches the gauge. You should be using a 150 lb. gauge. Don't use teflon tape.

Call egauges.com or another vendor and they sell you a bushing with the banjo bolt.
