I replaced the oil pressure sender on the top of my case with a sender which provides light activation and VDO oil pressure reading. How do I know which pole is for the light and which is for the pressure gauge?
The gauge also has three connectors for the gauge (not the connector for the light) which is marked +, G and grnd. What connects to what?
Thanks,
L. McC

do the poles on the sender have ANY markings ?

Mk is going to take some thinking - but by convention G is always gage, and by process of elimination ...

you can also test this with an ohmmeter. you'll have continuity (real darn close to 0 ohms) between the Mk and the case if that's the light; G and the case should give you measurable resistance.

I have the same dual sender.

How can I be sure it will work with this gauge?

wire them up in your kitchen and dunk the sender into boiling water.
or c-a-r-e-f-u-l-l-y heat a small container of oil and calibrate with a deepfry/candy thermometer.

to be SURE you send the gage and the sender off to Palo Alto Speedo and get everything matched and calibrated.

Hey Rich - does that mean that I can check my tire pressure with a thermometer? Sorry couldn't resist (IMG:style_emoticons/default/biggrin.gif)

actually - that's a good point, because if L is running an idiot light and pressure gage from his double-pole sender, it obviously CANNOT be the same double sender dv is using. (if it actually *is* the same double sender, one of them is not going to get 'the desired results' ...

(for your problem, get a BIG vat of 350-degree oil. put in your tire. you will have no further problems with air pressure :-) ...)

I think we are talking about the dual oil "pressure" gauge. Don't think that should go in boiling water, no?

you are correct...

but accurate air pressure gauges are not too hard to come by, so if it's pressure we're talking about, there you go.

I'm working on this right now, been out in the garage last two hours with this and 911 tach. I started a similar thread last night...

I just hooked up the 911 pressure gauge when turn the power on the gauge comes up to zero then when I start the engine it pegs the top. That can't be right, can it? I unplugged the ground and it stayed pegged at the top let the engine die and it drops to zero.

what's wrong here? guess I should make a trip to No. Hollywood Speedo too.

this bugger,

have to remote mount becuase it won't fit down in the tin.

any 914 friendly place like pelican or aircooled.net has it.

verify your connections, of course. the ground may be provided (more or less well) by another connection.

early 911's had 150-psi oil pressure gauges, the downside of which is that everything under about 15 psi looks like zero, which many considered alarming. (it's a 911, get used to zero oil pressure at idle :-) ...) anyway - mid-80's somewhere they yeilded to the complaints and in typical fashion, simply doubled the sensitivity of the gauge making it a 0->75 psi gauge, with more room to spread out the lower numbers.

the gauge must match the sender ... i don't think any Porsche gauges match any aftermarket VDO senders ...

Thanks everyone,
Gerry, that link was very helpful.
One thing I picked up was the comment about using teflon tape on the sender may prevent the sender from achiving a ground.

Well, actually, the G stands for 'Geber'. 'Geben' is German for 'to give', so it is the pole that gives the information...but ' Gauge' will be fine as well (IMG:style_emoticons/default/biggrin.gif)

Just teflon tape it for sealing and groud the sender to something else.

Anybody did this similar?

Greetings,
Walter

That brake hose may have 10 x 1mm threads, but they're straight threads, and the case has tapered threads. I use a grease gun hose, which has tapered threads (and it's cheap!)

Hmmm...so can the two terminal sender be used for only the idiot light by connecting only to the terminal not marked G? My engine has one of these, but the car only has an idiot light, no gauge.
