Phil D Posted December 23, 2015 Report Share Posted December 23, 2015 IF you have just one positive and one negative cable, then all positives go together and all negatives go together (parallel wiring). Like this but with one more battery: If it's the original factory wiring, it may not be that simple. I could be mistaken, but I seem to recall that Scrap once said that in the case of the rare four-battery T2000s, that the fourth battery was dedicated to hotel loads, although that's been a long time ago, and I could be mistaken. If that is the case, though, there will be some sort of circuitry that will recharge the fourth battery from the alternator, but isolate it from the other three for starting.

SuiteSuccess Posted December 23, 2015 Report Share Posted December 23, 2015 Phil, you're correct. He had a picture that he posted when we were discussing battery cutoff switches. Was a mess of cables. Maybe he will re-post and I will look for the thread 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

Scrap Posted December 23, 2015 Report Share Posted December 23, 2015 Man i don't even remember what pic or thread it was. Musta been one of the Ultracaps or sleeper no-idle options or something? The standard T2 setup for older trucks (42MT) with no disconnect is 2 left batts jumpered together and then a + and - cable going to the starter and 2 right batts jumpered and then a + and - to the starter. The maxifuse clean power wire and the eng/trans fuses (if applicable) come off of the single pin Deutch connectors that come off the battery jumpers. It doesn't really matter which one and they are gauged/gendered so you can't really mess them up. Link to comment Share on other sites More sharing options...
jkoenig24 Posted December 23, 2015 Report Share Posted December 23, 2015 The way the picture above shows will result in the FIRST battery (the battery where the wiring goes TO the vehicle) doing most of the "work" AND, getting most of the charge. The "back" batteries would work (and get charged) less. Ultimately, the batteries would not have the same service life. Ideally, each battery's posts will have a cable that goes to a central point and, from said central point, to the vehicle. Done that way, each battery in the battery bank would provide about the same amount of energy and, get the same amount of charge. Link to comment Share on other sites More sharing options...
Darryl&Rita Posted December 23, 2015 Report Share Posted December 23, 2015 Our 4 battery set-up is wired as per Scrap's description. This is on a 2000 T2.

jkennell Posted December 24, 2015 Report Share Posted December 24, 2015 In the above picture, just move one of the two supply cables to the far battery. (ie connect the + to one end, the - to the other end of the bank) That will help even out the draw. No camper at present. Way too many farm machines to maintain.

Ronbo Posted December 25, 2015 Report Share Posted December 25, 2015 My battery box isn't as nasty as that. It also doesn't have as much stuff attached to it. I have 2 banks and iirc they both go to the starter. Ron C. 2013 Dynamax Trilogy 3850 D3 2000 Kenworth T2000 Optimus Prime Link to comment Share on other sites More sharing options...
rhb Posted December 26, 2015 Author Report Share Posted December 26, 2015 thanks for the replies. I have a 5000 w inverter hooked up as well as a remote charger hook up under the hood so we are dealing with a lot of wires. guess ill try the spark method,() if it sparks it don't go there.)

tyates007 Posted December 26, 2015 Report Share Posted December 26, 2015 Here is what my 2000 T2000 looks like in the battery box. This when I changed the batteries out this spring. Link to comment Share on other sites More sharing options...
