AIM pressure sender bad?

[J Leonard]

Can a bad AIM oil pressure sender affect RPM and volt? Oil pressure warning came on for about one second. OP, RPM and volts all dropped on data while oil and water temps stayed steady.

did the dash re-boot? Is there a difference between the sample times of the various sensors that would make two of them miss a voltage glitch?

Just the one second drop of OP, volt and RPM, dash continued to work and data recorded. Need to check logging rates. Checked for obvious wire issues, loose, scuffed, pinched, grounds etc.

If it didn't re-boot the dash, since the volt sense is internal to the dash I bet it's internal. Something like a common reference voltage or power to a conditioning amp. Have you contacted Dave Ferguson?
