Capri Gauge Advice?

IIRC the oil gauge is actually oil fed isn't it? This is a long time ago (Dad has a 78 2.0 Ghia) but there is a voltage regulator bolted to the back of the dials isn't there as well?

The Ammeter is the most useless gauge ever, better off seeing if you can convert that to a voltmeter using the face.

Hi, It's very likely the fuel and temp gauges work through the voltage regulator. The Ammeter is probably supplied through a shunt, located elsewhere, because they don't want heavy battery cables onto the instrument cluster. The oil pressure gauge is probably ignition fed and earthed through a sender on the engine. None of them are going to be precision instruments.

The oil pressure gauge is mechanical and the feed is piped straight from the engine where the oil pressure switch would usually be on the inlet side of the block located in between the engine mount and the dipstick tube, this is on my yb I'm building so on your capri the oil pressure switch and take off for the turbo oil feed won't be there the pipe should be straight into the block



The gauge is fed by a black plastic pipe that runs through the bulkhead to the back of the clocks

99% of the time fuel and temp problems are caused by the voltage regulator, you can test if they are actually working by grounding the temp sender wire to the block to see if the gauge moves to the hot area don't do it for too long but it takes a little to move so no more than about 20 seconds will give you your answer, also do this with the fuel sender wire it should show full

If your in stoke anytime soon I have a set of 4cylinder clocks you could try

From what I remember regulator supplies 5 volt too both fuel and temp gauges.Cheating way to test gauges is just earth both gauge outputs and gauges she go to full for fuel and red for temp.
