all was good , drove 5 miles , vcar was running spot on

then the dash oil pressure warning light starts flashing , pulled over and shut it down , checked oil level , still well above Min

got a tow home , started with changing the sender , checked the pressure relief , still freely able to move , checked the conection on the sender and the wiring
started it up for a second , light was still on
found my old mechanical oil pressure gauge , plumbed it in , started the car , and on idle hits 70 psi , pressure increases to 90psi with revs

went for a drive watching the gauge like a hawk and all was fine .
only trouble now , the light still flashes then goes out , then stays on
what would be the most likely cause to this ??? , even unplugged from the switch , it keeps doing it ,
