Greetings Modelle, Re the compatibility query, when you say the gauge is pegged "with no signal power", wonder if you're meaning with the signal from the sender disconnected? Or with everything connected, and ignition switched on, but engine not running? Or......???
In any case, if there's a problem with the gauge reading, then sure it's possible to use a multimeter to see if you have at least some pressure on a first start. You could monitor the voltage at the connection between the sender and the gauge, which in your case I'd guess would be close to zero volts with the engine off (zero pressure, and gauge at max), and rising from zero as the oil pressure rises. In any case, whatever it is with engine off, you're looking for a change when engine starts. That shows there's some pressure, although there's no indication of how much. You'd have to know the calibration of the sender and gauge combo to assess the actual pressure value, and as these senders usually deteriorate wildly with age, you never really know the calibration. I'd venture to say that you're probably just as well off to note whether your oil pressure warning light goes out when you make your first start - you may not get much more info from monitoring the uncalibrated sender. Still, it wouldn't do any harm to monitor it - you should see it gradually changing as the revs rise, whereas the oil-light is just a simple on or off affair. NB For a first start, I'd always take out the plugs and dis the ignition LT (not the HT), and spin the engine over on the starter until the light goes out, and only then think about actually starting it. But others might have other views on whether this is a good idea or not.....

My 66 GT indicates the oil pressure pegged to the right with no signal power applied. Can I use a voltmeter to monitor oil pressure on a first-start?
