it could happen we're ready to test the hydraulic system with the pressure from the pumps
bart's standing by you ready with the towel are you just protecting yourself protecting my
hands okay so i got the aft and the forward valve shut off so all we're going to do is pressurize
this portion of the system if that works we'll start opening up the rest of the system
so these relays have this little manual override on them which is kind of cool
so i can use them as a switch i forgot that i got to get power to these so they can get power
to these which are essentially relays dude they're just big solenoids they let a lot of
power through from one side to the other side so now with uh this on i turn this breaker on
yeah there it is it powers one of them and then i can power the other one through here
yeah it's awesome both of these things are powered up
i'll have a connection from here to here when i turn these breakers on i run the pumps
it through a breaker wow look at this that didn't look good it's throwing a breaker
huh okay maybe we don't have the pump scored right yep there's 26.5 volts
it just immediately shorted it yeah so let's try reversing the polarity and see if it's happier
one okay that was a nice heart most dc motors will just run backwards
if you wire them up you know negative positive positive negative okay go ahead
take the breaker you kick the breaker off damn
that's not good yeah i'll take the motor off and see if it just spins without the pump on there
so we found a uh 40 amp breaker back here so we're gonna borrow it okay 40 amp breakers in now
nope well that's not good 40 amps isn't enough we got something wrong with that motor right there on
my side i say it's a 36 amp 24 volt pump so maybe we had the polarity right in the first place it
could be now we got a big enough breaker but the polarity is wrong so let's try switching that back
yeah so it's still not happy so the problem's going to be down in the motor or
it doesn't like 40 amps it needs more than that i can't imagine these 40 more than 40
amps to get started just a 36 amp motor just take the pump off see if the motor spins that phone
here it comes that's blind yeah the motor turns fine so it's not the motor hit
it oh flip the breaker again huh [ __ ] well so we eliminated the pump it's got to be the motor
so we're going to pull the motor out we're going to try getting a 12-volt jump off our batteries
down there that led acid to crank over the engine red is negative right i don't know are you sure
get it on there hold it it's running
it doesn't like the uh the breaker is not big enough or it's not 24 volt you know we
might as well see if it runs backwards with this test too so go ahead and hit it again
all right so which way is it running
hard to tell that's spinning clockwise here that's counterclockwise yeah so let's switch
them and see if this motor is reversible yeah i know okay so it doesn't reverse the direction
it's always the same way and it runs great on 12 volt but they sold it as a 24 volt motor
so let's try it with 24 volts without the breaker involved or with a bigger breaker well we could we
could hook it directly to the 24 volt battery but that's nothing i want to do to my 24 volt battery
it's should work well i don't know if it's a 12 volt motor when you hook it to a 24 volt
motor battery it should just spin twice as fast it's throwing a 30 amp breaker
you know it's throwing a 40 amp right here and it's supposed to pull a 36 amp load so
let's go see if we got a bigger breaker okay testing it with a 63 inch breaker up turn it
off well i just flipped the breaker motor spun the motor spun and then it flipped right off
so is it a 12 volt motor or is it a breaker that's too small still
i think it's a 12 volt motor i'm thinking the same thing now we're pushing 60 amp
63 amps and it still throws the breaker sponge it a little bit yeah i think it's a 12 volt
better the other thing we could do is wire them into series with 24 volt because then the first
motor would draw off 12 volt the second motor would draw 12 volt so the voltage would be right
we get to run both pumps off 24 volt but you gotta have both of them running okay
the motors are wired in series parallel is easy to think about you bring you know
positive down here then you run another wire where they're positive here and then the current flows
in parallel through the motors and back out through a negative on one motor and a negative
on the other motor in series power flows in here on this motor flows through the motor
out the other side down there and back around to the other motor and then flows through
it and then back to the batteries so the motors are in series this one will absorb 12 volts and
this one will absorb 12 volts because 24 volts is coming in there which is look and we took
both pumps off because we're thinking we don't want the loads to be different across the motors
okay so we got our amp meter out on a jumper cable and watch this one motor running
it started off at 40 amps just dropping down no load of course the pumps are disconnected
now i'll go over here we'll do two of them in series that's working too
oh yeah it's running they're both good motors they both like 12 volts they like both will work they
hate 24 volts and they will not run they throw the freaking breaker they're only pulling 30
40 amps here so the 30 63 amp breaker is fine so it's got to be something with the voltage
now they're running 12 volt in series so there should be a voltage drop of
6 volts across this motor and six across this one let's see
ground there 5.6 volts so that's what i expected should be 12 volts across here and here
yeah 11.5 and then 0.6 so the voltage drop is doing what we thought in series is just not
doing it for 24 volts and they don't sound like they're running fast listen let's see if it runs
sounds like it should be sound like it runs faster this way oh yeah that sounds like twice as fast
oh yeah so they're happy doing it with 12 to 6 but not 24 to 12. both can be turning all right hit it
oh we had the wrong breaker up there we had a 40 amp and we had switched in
63 and they're running oh yeah that's definitely both of them let me do a voltage i'll check
so we should see 12 volts 13.1 yeah that's what we want sweet hit it 106. yeah that's the problem so
they make breakers that are slower to react the 63 is actually doing 106 amps for a little while the
40 it didn't make it but you can have you know faster reacting uh and i got kind of middle of
the road one there so we're good we use the 63 amp we put them in series now the question now
is how much more amperage is it going to require for them to pull these two uh pumps here because
it's got to start both of them okay the pumps are hooked up we're going to make pressure hit it
all right they started and ran so they can't turn the pumps and the question is how much pressure
can they make you know we open up the rear system we'll see it on the valve over there the gauge
well that 63 amp breakers gonna be just on the edge look at that here
they got the air to the system that regulator must be blowing off now
a piece of tape on there to mark where the oil is nothing on the gauge oh stop i see a problem
you gotta open the valve that supplies the oil to the pumps there is our problem
well they're pressed yeah they're running drop that sure sounds different
yeah gauge is coming up oh okay yeah we saw movement so we got some pressure
let's see what we did you can hear it you can sure hear them yeah you know the cool thing would be we
need to watch the amp meter too and see what it's actually doing so the question is is that breaker
big enough to start these pumps when they have to start loading with pressure oil yeah it's all gone
it is all gone sucked it all away so we fill it up okay it's oiled up wow
so it was starting under load they did start
that's good about 480 pounds on it that breaker's gonna throw that's 200 amps yep on 204 205
he was up to like 800 psi before holy [ __ ] so it's doing pretty good it definitely
is pulling 200 amps so i'm going to open the valve to the accumulator the pressure
that's currently in the system which is just pipes and hoses we'll go into the
accumulator and we'll run the pumps for a little while and charge the accumulator
up a bit so opening the valve we should see that drop off to next to zero there it goes
yeah you can hear it okay there's the first leak i don't think i ever tightened the accumulator
into it now yeah i just pushed that in there by hand i never tightened it down
that's a nice one okay go ahead and turn all this build up a little pressure
it holds pressure it doesn't come down it means we got no leaks
this check valves aren't 100 they always going to leak a little bit pull that pull that out
and then i can pull all the hoses out of here all righty good god it's like giving birth
how'd you get it in there kind of the opposite of what i just did
okay so now we can see leaks if we have any found and fixed another leaf and we're happy
that it's holding oil it actually still has some pressure in the system so we're going to open up
the forward part of the boat which is this valve right here that pressure will drop off
yeah there it goes
okay that's everything so these hoses will supply the deck crane so they just have plugs in them
that should be a no-brainer we pressure tested with nitrogen gas that much and then the lines
come in here they go overhead one of those is air the other two are hydraulic so this should
be pretty easy peasy we get to work the anchor if this works looks like oil i don't think it is oil
i think it's water that hatch up there where the deck crane is going to mount leaks a little bit
you could get down there and lick it get down there and lick it
go ahead hold your breath oh i just saw a drip uh you're just saying that you're just saying
that i just saw a drip of water all right i'll get down there but oh dog oh sweet rainwater
man that's beautiful look at that isn't that gorgeous
it's here a little bit i heard nothing oh women were turned off ah the sound of oil yeah
me too all right i think that's all the pressure it had a little celebration blast
you even got a giggle out of the kids next door and i'll give it like 30 seconds
that sounds good hey it's moving check it out
no leaks don't try to stop that thing from turning
uh he must have turned it off or through the breaker kick it on again and i'm going
to go shut the valve so just let it run until it throws the breaker all right now the whole turns
going the other way
so
bye
