    You should have fuses in the back also, if you cable shorts out in the middle, the car will still burn down because the battery in the back also supplies the current 😮

      That’s why I did multiple fuses under the hood then multiple runs of 00 to a fuse block under the rear seat then going to the amps and batteries

    With no battery isolator when one battery starts to fail the internal resistance of the weak battery will prematurely drain the other one. Also the charging system will over charge the good battery ruining it, and it will cause the alternator to fail prematurely due to trying to keep the batteries charged. Do not do this.

      What if you want a second battery to for say an alarm system to keep it from draining when left for long periods? Isolator won’t work

    • @1JamesHamilton1
      @1JamesHamilton1 7 місяців тому

      @buysncharge not with an isolator, when used it will help prolong the life of the primary battery by removing it from the circuit to be used only when starting. When connected properly, the secondary battery will be used to run your accessories. That way, you always have a hot battery for starting. A good isolator will automatically provide extra starting power from your secondary if it calls for it. There are many benefits to having an isolator. Again, if your accessories drain your secondary, the primary will still be hot. Unless you have some other problem.

    • @1JamesHamilton1
      @1JamesHamilton1 7 місяців тому

      @Tairone1337 yes it will. The isolator is to prevent your primary battery from being drained by your accessories. If your accessories deplete your secondary battery, the primary will still be able to start your vehicle.

  • @Gr8rome407
    @Gr8rome407 2 роки тому +7

    Yes its true it can run fine without an isolator the problem is if one of batteries go bad the good battery will slow charge it and if bad battery can't hold the charge good battery will drain all the way down then both will die it happened to me once

    Using a Heavy-Duty True battery isolator provides several advantages for truck with auxiliary battery setup.
    Reliable Battery Management:
    Automatically ensures the starting battery is charged first, then charges the auxiliary battery, preventing the main battery from draining and ensuring reliable engine starts​ (True Battery Isolator)​​.
    No Voltage Drop:
    Unlike traditional diode isolators, True isolators have no voltage drop, maintaining optimal charging efficiency​ (True Battery Isolator)​.
    Dual Sensing Technology:
    Monitors the voltage of both batteries and engages charging for both if either battery is receiving a charge, which is particularly useful when using external chargers​ (True Battery Isolator)​.
    Durable and Compact Design:
    Built to withstand harsh conditions with features like waterproofing, heat resistance, and anti-vibration casing, ensuring longevity and reliability in various environments​ (True Battery Isolator)​​ (True Battery Isolator)​.
    Easy Installation:
    Simple three-wire installation without the need to bypass existing alternator wiring, making it user-friendly even for novice installers​ (True Battery Isolator)​.
    Cost-Effective Solution:

    I've used an NVX 500 amp smart isolator in my three battery (parallel) suburban/200 amp alternator. The isolator crapped out after two years and I just removed it, thinking it would be OK for a while. Low and behold I developed a long crank, which progressed to a no start after about a month without the isolator. Same brand/spec batteries purchased together. The voltage always seemed to be >12.6V, but two of my batteries were profoundly dead (one being the start battery) as diagnosed with a proper battery analyzer. The normal surface voltage was coming from the one good remaining battery. So, yes you do need a battery isolator if you run a multi battery system.

    A Isolator is use so your back battery won’t kill your front battery also depending on your isolator amps it can protect your system equipment sorry but your not explaining what isolator can do also you need to fuse your battery in the back remember that having a battery in the back is like having a battery in the front, The as a reason you’re not getting good voltage is because the fuses in the front you said is only a 120 you supposed to have a 300amp that will work a lot better I’m just saying
