Pressure Gauge

I am currently rebuilding my 1983 chevy c10 and on the electric oil pressure gauge connection at the sender I am only getting 7 VDC to ground What can I check I think I am supposed to be getting 12 VDC at this connector

It may be normal. The pressure gauge in the dash may have an internal voltage regulator built in, so voltage variations in the electrical system of the car do not affect the oil pressure gauge readings.

Does the gauge and sender combo work?

What is the problem if any?
The oil pressure sender varies the resistance to ground. As the oil pressure increases the resistance decreases.
When the engine is stopped the OP is 0# and the resistance is infinity. As the OP increases the resistance drops but will not reach 0 ohms which would give you 12 volts at the sender.
OHMS law.
