great stuff on your channel, so i bought a 2008 Glastron gt249 and i want to update the housing battery from one amg to 2- 200AH in parallel addition to 400 AH lithium phosphate, what and/or should i do to make this a safe transition on my boat! thanks
The standard alternator on my Volvo D1-30B outputs approx 13.9 volts at 2,300RPM. Will this be damaging my 75Ah AGM starter battery and 2x 95Ah AGM Service Batteries, both of which require 14.4v bulk/absorption and 13.5v float?
One of the BETTER Questions and Great answer. Are outboards acceptable to this type of smart regulator? I was thinking of adding two AGM's this spring and know my gauge reads 14.4 volts while underway. Love questions from viewers, learn so much.
Hi Jeff - You say that the alternator connects to the post of the starter motor but I thought in one of your other videos you said the alternator should connect directly to the battery.Does it connect to both directly ?
Hi Col . The wire from the alt. usually is always a # 10 gauge wire . It goes to the starter alt. as Jeff mentioned . There is always from the starter to the battery your large battery wire . All you need is a cable from the Alt. to the starter that will handle the amp output over the distance of the cable used . I used a #6 gauge wire . Use OFC wire and not CCA .
Good question, you should only have one positive connection to your alternator, either normally connected to starter solenoid or connected directly to battery bank.
@@PacificYachtSystems Hi Jeff - I also am upgrading the alternator on my Catalina 36 from the stand 50A to a 105A. My positive output wire from the alternator to the solenoid needs to be a different gauge than the existing, but then so does the (much longer) wire from that solenoid connection to the battery, correct? It looks like that wire needs to be a very large and difficult gauge, like maybe 2AWG based on the length with all of the turns. Routing that one has me concerned. It's actually going from the solenoid to a charge isolator (ProMariner ProIsoCharge), which will then have distribution wires going from it to both my starting battery and my house bank. Presumably those wires also need to be able to handle the full output current of the alternator as well?
Lots of great info Jeff!! If my alternator has an internal regulator, and I would like to charge my house battery, than from the house battery, use a DC to DC charger to charge my starter battery, would I want to rewire the alternator so that I could use an external regulator?
I've upgraded my stock alternator, a larger agm battery and added the big 3 upgrade all ofc 0 gauge wiring. My voltage stays from 13.8 to 14.1 with all my accessories on. Will that voltage regulator harm my cars computer???
For a 12 volt system, most alternator regulators output 14.4 volts on the positive post of the alternator, by the time it gets to the battery, your battery voltage might be a few 1/10 of a volt because of voltage drop and loads.

Yes, absolutely
I absolutely love these short Q and A's. Thanks from a Swede.
Glad you like them!
Hmmm you just gave me some very good info
Glad to hear it!
I don’t why it is, but this is the second time recently that I had a specific question and I found the answer on that exact day’s customer question.
We're not sure why either but we like how that's going! Thanks for watching.
Another great video Jeff, thanks for taking the time and sharing your knowledge and experience. We appreciate it
We appreciate you watching! Thank you

Big fan of external regulators... it's a great way to get faster and smarter charger from your alternator.
Great video...sounds like an EXTERNAL REGULATOR is a must have regardless of ALT size/capacity.
You are correct
Does an internal regulator harm the battery by outputting a constant voltage?
It's not perfect, but I wouldn't worry about damaging your batteries.

Thank you, please move to the east coast. Lol
Good one, i'm from the East coast, love it there too.
Hello,your video is great,I want to invite you to take the Video for our product?Thank you for your reply.
Yes please
@@PacificYachtSystems Hello,I need to know how to contact you?I have send you the E-mail ,however,you didn't reply me.Thank you.
