Yanni,
First what kind of boat other than a generic S/V, someone out there will
perhaps have the same model for comparisons. What model brand of engine and
what brand of alternator ? Do you happen to know whether or not you are using
an external voltage regulator on the alternator ?
Could someone more knowledgeable clarify the "field connection on the
alternator
This is what turns the alternator on. Most boats have it hooked up to an oil
pressure switch so that it cannot be "on" without oil pressure. Ergo you shut
off the engine and it turns off.
You turn on perhaps an "ignition" switch, and it supplies the oil pressure
switch, which then turns on the alternator after the engine starts, perhaps 5
to 10 seconds. Most of these arrangements have an oil pressure switch
normally closing at +/- 4 psi.
and the battery switch
What the above has to do with your battery switch.....or for that matter what
"battery switch"
A one/both/two one or something else. I have no idea at present other than
you have to have that switch on to energize the "ignition" switch and the rest
of the instrument and engine circuits on any boat I've ever been involved
with.
and what exactly it does effect.
Best explanation is a compilation of both the answers above.
I believe I am loosing current and one of the batteries drain back. It's
fairly new and I can't understand why the voltage drops. I did the old test
interrupting the positive terminal with a light hooked up and it lights it
comes on, that means there is a leak.
It means you have a completed circuit somewhere therefore your next statement
is not correct, as you do have a completed circuit of some type, with the
lightbulb lit.
All the circuits are ok.
I tried the battery directly hooked up on the starter solenoid.
So how were you recharging it ? and is this the battery that runs down ? If
nil on the charging and it still was running down about the only thing it could
be is a starter solonoid.
Any Ideas?
