hi

jeff cote here with another session of

boating tech talk

so we've got a question from a fellow

boater steve steve asks jeff

i've got a single outboard and i've got

one start battery and one house battery

by the way right there i'm liking it

right so you've got an outboard sure

you have one battery for starting the

engine but it's always good to have a

backup battery

for your house loads okay and even if

you don't even have divide and conquer

and do engine and house

then you should have battery one battery

tube if you have an outboard you should

have two batteries

because when we're on the water you

don't want to have all your eggs in one

basket

and have only one battery that can start

the engine always

always advisable to have a second

battery to start an engine

especially the further afield we go and

if we don't want to have a terrible

experience on the water

having a second battery to start an

engine is a good idea so

steve has two batteries he has an engine

battery and a house battery so far so

good

he's saying jeff here i'm thinking about

installing a blue seize battery combiner

this is

blue cs call them automatic combiner

relays they're just a marketing word

um it's basically a term acr

automatic combiner relay or blue another

company

calls it basically vsrs voltage sense

relays

they're just marketing words to describe

basically

a battery combiner

so steve keeps going and he says jeff my

house battery is connected to the acr

post

a and my star battery is connected to

the acr post b

okay all right so far so good and he

asked jeff

both wires are connected via an mrbf

fuse

150 amp love it so far so good

very important when we're putting

battery combiners on our boats it's

essential

to not take shortcuts don't take

shortcuts i'm telling you

the pitfalls are plenty and you won't

even know that you did something wrong

because you just don't know

so always follow the instructions so

steve's doing the right thing

he's going battery to battery and the

acr is right in the middle

so far so good i like it now he asks

does it matter what position the battery

selector switch is on

right and here's a question for the acr

or the battery combiner to operate

properly

good question because it's confusing you

know battery combiners

offer battery it basically allows two

batteries to be put in

effectively in parallel whenever there

is a charging voltage

acr works regardless of whatever the

battery switch is battery switches are

something else

yes they would manually put potentially

your batteries in parallel and of course

they would

but the acr even if the battery switch

was not there even if the battery switch

was off

if it's on one if it's on two if it's on

both

regardless of what that battery switch

is doing that it exists

or not does as long as your battery

combiner is connected to both batteries

directly

via fuses and that battery combiner is

in the middle

the battery combiner is going to allow

both batteries to be in parallel

whenever there's a charging voltage and

you don't have to worry about the

battery source selector switch

and that's the beauty of the battery

combiner it allows you to have your

battery

your engine battery that gets a charge

when the engine is running

assuming that you're started off that

battery it will share

that charge with another battery the

battery combiner

and so steve you're doing it the right

way and you don't have to touch the

source selector switch

to share a charge you certainly do have

to use a switch to start your engine

because with the engine source selector

switch off

you should not be able to start the

engine and that's a good step to do by

the way

turn the battery switch off and see if

your engine starts and if it does start

then you know your battery switch is not

properly installed

but with the battery switch on your acr

should work no problem

because it's going to chair

automatically that charging voltage to

your house battery from your engine

battery

so that's an excellent question steve
