Does anyone have a recommendation for a marine electrician in Beaufort SC? That's our next stop, and we have instrument and alarm circuit issues.
Easier/better than PM or replying here (though you could, to make others' searches in the future faster), text me at 770-887-0397, or email my name, all one word, at gmail, if you have a referral.
Crushing/boring detail below:
I suspect the alarm circuit may be the power source for the two oil
sensors (one presence of, and the other, pressure of, oil) and may be
related to my hour meter seemingly having stopped.
The tach is, indeed, from the alternator. If it weren't for the
combined, instantaneous (all bad at once) failures in the others, I'd
look to the pigtail leading to the tach.
Somehow, the temperature gauge has both light and reading, but I think
it doesn't rely on the ground fault which triggers the oil alarms; I
speculate the oil pressure (a single-line sensor) is sending a
variable voltage, and if none is present, or, measuring resistance,
and if none, gives the alarm circuit.
The alarm circuit power has a sizeable fuse on the supply side; it's
good. I metered no voltage from the incoming fuse end and ground, and
checked that modus on another circuit which was energized. So at a
minimum, power's not getting to the alarm circuit.
The alarm itself has an LED indicator that power's getting to it;
there's a switch which can turn off the alarm if needed, but aside
from allowing a blip on turning off the engine, and killing it until
the key is turned off, it's rarely used.
There's too much we need to do otherwise for me to tackle that
currently; is there someone else you'd recommend for that?
Thanks.
