[Music]  you  [Music]  okay we're gonna briefly talk about  external regulators now this one is a  little scary because there's a lot of  magic in an external regulator  ultimately the first thing you need for  this thing to work is you need power  right and the power is going to come  generally actually from the back of the  alternator not the battery that's where  it's going to come and there's good  reasons for that not gonna go into why  but there's really good reasons for that  the next thing that's just powering and  that's just having it like turned on  it's like your TV plugged in then you  need the regulator to actually be turned  on and that happens to the ignition wire  this wire right here Brown and you'll  see light something on the thing that's  going to tell you it's working it's  going on and that's one step and the  next step is once this receives power  it's connected to power it's been told  to turn on and this is how it turns on  then what's gonna happen is it's gonna  output on this wire here a blue wire the  field voltage that's actually what  drives the alternator and that's the  thing that you actually want to measure  like as my alternator being told to work  full field means whatever the battery  voltage is 12 volts you see 12 volts on  that wire as the battery gets four and  four it starts from bottling down you  might have problems with your  temperature sensors so what I've done  sometimes is I'll actually pull away the  temperature sensors because if there's  dead shorts on those they might think  the battery is actually overheating and  they'll stop the alternator from  actually outputting their thing the  batteries are in one called thermal  runaway I've written articles about this  it's a real thing  that's why black top batteries catch on  fire thermal runaway when they're  charging so this device might think that  you're in a thermal runaway situation it  might not actually stop the alternator  from charging via the field voltage so  for troubleshooting sometimes I'll  actually disengage these two wires the  temp sensors remember your alternator if  you've got an external alternator you're  gonna probably have the alternator Y  directly to the battery make sure that  fuses on that's another thing too and  make sure and this is a really other  good one  this volt sense make sure that it's  still there and it's still working the  Volt sense is absolutely  and I didn't write it down but there is  a fuse on that there's absolutely a fuse  here and that fuse probably is blown if  this doesn't sense volts it's not gonna  turn off it's gonna say why would I do  work there's nothing to charge I don't  see a voltage so it's actually looking  at voltage and saying not the power  voltage that's different it's actually  looking on a specific wire saying what  is the voltage there if it doesn't see a  voltage it's gonna say well there's  nothing for me to recharge so I'm not  gonna work and that's how an external  regulator works so I would say first  thing make sure that you have power to  the device you have ignition power to  the device when you turn the ignition on  make sure the voltage sense works and  after that look at what your field  voltage is and make sure that your fuse  is actually still there on your  alternator I shared my enthusiasm  yesterday on how I love these devices  they are magical if I could only  high-five or hug the inventor I would it  is one of my favorite favorite devices  on a boat it's just it's a God device  it's perfect it is absolutely perfect it  is just one second question no such  thing  literally no no such thing  yeah it removes an internal regulator on  a boat it sort of converts your  alternator to smart three-phase profile  charge profile right so it's it's a way  to increase your alternator output  dramatically without changing the  alternator size while you would buy well  you don't have to you would you'd  recommend that you would you rewire the  alternate output post to the battery  that needs a charge but that's not the  only reason you're actually you take  your existing alternator off and you'd  have it modified to what's called an  external field it's about a $50 $75  charge at an alternator shop and then  they're saying you know what instead of  having a dumb internal regulator you're  gonna have it smart something else  outside and we're going to remove the  external review the internal regulator  from it and you're gonna drive  everything through what's called the  field voltage which is this blue wire  here yes question  yeah Oh God are you including new  components in the system yeah I'm loving  this yeah what's the question it's  pretty much the same thing what would  happen is you'd have anacs-- you'd have  you'd have here in between you'd have  this battery isolator which is the fat  that would be the alternate input and  then the FET output would either go to  this battery none of the battery over  here you'd want to see the voltage sense  wire going to most likely you'd have to  be not on the alternate input post  because there's no battery voltage there  you'd have to be probably at the house  battery still that's a big big big big  big problem that's a lot of bigs with  external regulators that are just  MacGyver din MacGyver doesn't read  MacGyver's trying to solve the world's  problems in an afternoon in 60 minutes  and he doesn't realize you're the  voltage sense wire if it's in the wrong  place you will cook your batteries you  have no idea the world of hurt you're in  is gonna be so expensive it's gonna be a  humbling experience you're gonna want to  hug it out you're gonna want to hug it  out  if that voltage sensor wire is not in  the right location you could cook your  batteries and bring them to absolute  complete death there is no saving them  after that so voltage sense follow the  instructions if you follow the  instructions no problem if you don't  follow the instructions and you value  money or your time you're gonna want to  have an emotional talk to talk with  someone tell you that life gets better  because this can be very expensive  voltage senses everything remember this  thing is actually figuring out if it  needs to charge or not if it's not  seeing voltage or the voltage is not  increasing when it thinks it's seeing a  voltage but it's on the wrong battery as  I say I see 12 I don't see a voltage  increase work harder I don't see  anything work harder and you can see a  battery voltage go to the other  batteries seeing the alternator but  these two wires are not in the same  place and this is to this  starter battery and this is the  alternator this battery is gonna go 18  17 volts and by the way a battery can  never go to 17 volts never black and  white it's a life event it will never  recuperate there's no amount of cuddling  or anything you can do to that battery  that burner is done it's toast it's  going to the graveyard so you absolutely  need to have that voltage since wire at  the same battery where the alternator is  connected if you don't you're in a world  of hurt and you won't be troubleshooting  the problem at this point its  catastrophic like there is no  troubleshooting you're calling someone  in well you want to have the same  battery bank or batteries the same thing  because the battery bank could I use the  word interchangeably what's the  difference between a battery bank and a  battery to me there isn't one a battery  is could be one battery in a battery  bank or there could be multiple  batteries in a bank but Tim either one  in the same battery bank can definitely  be made of multiple batteries questions  on external regulators no I always I  always good question I always use it to  where the alternator is connected so  wherever that alternator wire is  connected to I'll have the voltage  stents connected to the same place and  remember I did not show you for  simplicity I'm not showing what it's  called the positive on switch  distribution post which I love to use  all the time but generally that wire and  that wire are going to be on the  positive on switch distribution post  because you can't bring all these things  to a battery right the reality is your  battery is not a connection point for  everything the manufacturer of your  battery gave you a positive post and a  terminal and negative post those are  supposed to go to distribution posts and  then from there they're supposed to go  to everything remember like I are always  thinking about it's amazing how when  they were thinking about those names  they're talking about in electricity  branch circuits Oh a tree trunk clients  a tree right there thinking about one  thing connected to the earth the large  lines are trunk lines then you get  branch circuits as it fans out  a tree analogy is very good how many  trees do you know that I have see  multiple trunks it in the ground  generally it's one trunk right and then  it fans up generally right and that's  how it should be correct what I call  that unsweet distribution that's right  and I'll show you I mean I can look will  go back and I'll bring it up at the end  I'm showing overall the diagram of all  will show you that again yeah okay it's  great but thread lightly right if you're  gonna install that on your boat tread  lightly tread lightly
