Stuttering compressor

[sp33chy]

Interesting, the watchdog wasn't complaining on the dashboard however. Maybe I just fed the watchdog a step too late which wasn't enough to show up on the dashboard but was enough to make a difference.

So to any teams having this issue: try feeding your watchdogs more often.

We had the same issue the other day. For some reason, the problem seems to have corrected itself. No changes in programming were made. While we were having the problem, we changed batteries, thinking it may be a voltage/dying battery issue. A freshly charged battery made no difference.

No, that's not normal, unless you have a fast air leak.

Normally, the pressure switch goes on when the pressure drops below 95psi and turns off when it gets above 115psi. Then doesn't turn on again until it again falls below 95psi.

What does the gauge show?

Your wiring looks fine.

Have you measured the resistance across that pressure switch like I mentioned before? It is possible that your switch is defective. That switch should open (resistance jumping to infinite) when the air pressure reaches 115psi, and it should close once again (resistance jumping to 0) when the pressure drops below 95psi.
