High Oil Pressure

High Oil Pressure
Hi folks,
Here's the current situation. Oil light on instrument cluster is ON, and Oil Pressure Gauge is at MAX (~5).
Most relevant information (maybe):
Engine has been replaced. (Long sad story.) Runs fine.
Pressure has been tested at the switch location with an independent tested.
Oil filter has been changed twice.
Oil has been changed.
Oil level is at high end of the second notch.
Other things we tried before the real pressure tester:
Pressure gauge switch was broken as it turns out, and has been replaced. Still at MAX.
Oil light is on regardless of gauge even being plugged in.
There doesn't seem to be a short anywhere.
Dash lights and instrument work has happened - I replaced the dash.

Also - the amateur electrician in me worries about flipping polarity and frying things. That's not gonna happen here?

Could it be the low-oil light? That's a different sensor from the pressure

So back to the original question then - what could raise the pressure like this? Engine sounds fine...

Oooooh, I found this on the intarwebz: http://944foot2thefloor.blogspot.com...-oprv-oil.html
That looks like juicy reading.

Could do that - but the issue remains that with an external pressure sensor, they're reading a 6+, so the current sensor isn't specifically an issue (I guess). It's just what got me alerted to this pressure issue.

It's common for oil pressure to read 5 bar (possibly slightly higher) after start up on a cold engine.
What's your oil pressure after it has warmed up? Should drop down to around 2+ bar at idle and normal operating temp.
What weight oil are you using?

I drove 20 min and it stayed pegged at MAX. Using 0W-40 synthetic in there now.
