making a Start all out of my alllis

[powermax_paul 1]

Brad, If you’re jump starting Mack trucks, you probably already much of the following. Getting plenty of current is what’s important. Use a high capacity battery (batteries) and HEAVY cables and clamps (I use welding cable). One large 12 volt battery is all that is needed. However, multiple batteries are easier to handle and cheaper to replace. An alternator is nice to have, but not necessary unless you use the setup constantly. The batteries can be recharged in the shop between uses. I have a 12/24 volt setup (at least 2 batteries are required) rigged in a pickup truck equipped with a 120 amp Leece-Neville alternator (top illustration). A 24 volt jolt will crank the coldest diesel (just make sure whoever uses it knows what they’re doing or you’ll have plenty of electrical repairs to keep you busy). The lower illustration is just an example of "series and parallel" wiring to end up with 12 volts output. An alternator could be driven off your tractor rear PTO (just like a tiller). Just make sure you mount the alternator so you get the proper rotation, and make sure the "startall" system is isolated from the tractor electrical system. http://home.att.net/~herb.niewender/startall.jpg

I'd think a trailer would be a nicer way to pack around a large amount of battery power, and run an alternator off the rear belt drive (if the B12 has one). The tractor would steer nicer without having a couple hundreb pounds of batteries counterlevered off the rearend.[A href='http://www.wheatfarm.com']http://www.wheatfarm.com[/a]

i want to build a start all on my B-16, i mean 12. i am planning to buil a platform on the back to carry 4 large 12 volt battiers and i want to run 1 or 2 alternators off the tractor to charge the battries. what i want to accomplish is somewhat like a startall. i want to be able to drive the tractor up to a dead Mack and hook it up and Jump start the mack. no cords, no charger, and a reason to have another allis. does anyone know how i should go about hooking up the alternator(s) to the batteries?

JC Whitney sells dual battery kits. 2 kits 1 for each alternator and have each alternator charge 2 batteries. Hook 2 batteries in series off the same alternator, then hook the next set up in series off the other alternator. Then hook both sets up in parallel. This should give twice the amperage of one battery and also twice the voltage of one battery, i.e. 1 battery is 12Volts then 2 would be 24Volts and if you were using for example, a 1000CCA battery you would have the equivalent of a 2000CCA. I'm no electriction but I don't see why it would not work. John

Just had a thought for one altrenator. Hook every thing up the same way except, use one dual battery kit off the alternator, then use that to go to the other two dual battery kits. Hopefuly someone can confirm this for me but it seems like it would work. John

Two batteries or sets of batteries should be connected in parallel (+ to + and - to -). Negative should also be grounded to frame. Could use a GM style self-regulating one wire alternator. Connect the wire to positive side of the batteries. Make sure mounting bracket is grounded to frame. Paul
