P1000 Ok. I killed my battery...

[tjoreo]

Thinks @joeymt33 for the info. That would definitely be something to think about. I'll have to do a little more tinkering. I sure appreciate all your advice. I'm just think with the few items I want to add, that a second battery would be overkill. But I guess a little insurance is never overkill. This lvd just might go on the boat, like it was made for.

I've never messed around with a low voltage cutout but jackal may have some good insight. It sounds like it can be used to kill only certain accessories.

A properly installed isolator and properly wired accessories would only kill the feed from draining the OEM battery, the Winch would still draw from the Aux battery until you drain it entirely.

So, could you have everything on your vehicle run through the low voltage cut out but have the winch wired to the battery? That would be a good idea. That way, even if you left your key on or radio or anything else, you would be protected.

My isolator is between the batteries.
The control power for the isolator is
from the aux battery. That way, I didn't
have to get into my factory wiring
harness. The power required to hold
the isolator closed, is what killed the
batteries. All of my add on lights &
winch are powered from the aux
battery.

Funny, actually. The reason I
added the isolator & aux battery,
was to keep from draining the main
battery...

Later!

A proper battery isolator would have prevented this from drawing down your OEM battery only the AUX battery, did you not install one? or did you wire things up incorrectly that defeated the isolator?

That is odd. A typical Isolator should be in an open state anywhere from 12.1 to 12.6 volts, meaning when the machine is not running and the system being charged by the stator at 14.1 volts it "should" open disconnecting the OEM battery from any further draining. On mine there is a green indicator led that is lit when closed and batteries connected but about 30 seconds after shutting off the engine the led goes out indicating the main battery is no longer connected to the circuit. Possible you got a faulty one?

What isolator do you have? Check to see if the isolator is hooked up backwards, some of them have a terminal where the the power wire of the factory battery hooks to and on the other side of the isolator the accessory it will be labeled, or it could have a arrow on it to show the direction of the current flow.

Are you sure you do not have a perko switch and not an isolator? A perko will do what you are saying but an isolator should do as Jackal is stating.

I have this installed.

I have control power pulled from my aux battery,
so it does seem like as that battery died from holding
the isolator closed, it would have dropped out, but
with the batteries tied together, their average was
holding the isolator closed, until both were drained
down past the point of recovery. The primary battery
has 5.5 volts & the aux battery has 2.8 volts now

I installed new batteries yesterday.
Test drive last night. No issues.

something doesn't sound correct. a properly wired isolator between the batteries will prevent an accessory from draining both batteries below the isolator set point.

 

[Johnny_C]

This isolator has no set point.

Either it's energized to tie the
batteries together, or it's
de-energized to open the
connection.

Ah, now I understand.
