Zero oil pressure at 4000 RPM

Sonalert; there are hundreds of varieties (audio patterns/voltages, etc.) I just grabbed a link to the first one I saw...

Re: Zero oil pressure at 4.000 RPM

Google "sonalert". not sonar alert. (my bad). They emit a high pitched sound when activated.
Also for Positive ground, just reverse the wires, however it might work wired as - ground.
Contrary to popular opinion, a lot of stuff works either way. Horns, light bulbs etc.
LED's however care, coils and ammeters too. That's why its so easy to reverse our cars.
It would be simple to wire a sonalert to go off with both oil and water Temp. switches.

Well, that rules them out for me. Like, I suspect, a lot of us my high-frequency hearing retired years ago (if you have trouble following conversations in crowded, noisy places you know what I mean).

No Problem! I'm sure we can engineer a link between any Healey sensor and ..... this wearable.

Nothing like a "gentle" little electric shock to alert you to low oil pressure.
