Pantera L Oil pressure gauge strange reading

I have a strange problem with my oil pressure gauge. At startup the gauge reads a correct three quarter along the scale reading. Sometimes, the gauge will jump ( not progressively climb ) from the correct pressure to off the scale. My deductions so far are that it may be an electrical fault, possibly related to the cooling fans at the front of the vehicle. I have 2 afermarket fans at the front, one is controlled manually be means of a dash switch, the other is supposed to come on automatically when needed, but I have never seen it on, so I assume it isn't working. Could it be that the thermostat is trying to turn on the second fan, failing and somehow affecting the voltage to the pressure gauge.
