Electrical issues

[analog_me]

Hi all,

Recently my oil pressure gauge is showing zero the moment I turn right then back to about 4 once driving straight ahead.
The car is a 1999 car all of the instruments are marked as "Caterham" ...
Can you give me any hints on what to look for???
If have very little of at any electrical knowledge.

Many thanks

The senders are notoriously unreliable, I prefer the reliability of a mechanical gauge.
