Re: Dual battery setup question
I have the positive to positive, then down to the starter, one neg to the frame, and one neg to the engine.
End result is 12 volts, and double amps. |

Re: Dual battery setup question
just tie the positives together and ground each battery and you are good. I have hooked up hundreds this way. This is how every diesel on the road is hooked up.

Re: Dual battery setup question
Agreed with above but there is also a switch you can get in between the setup (cant remember the name) that basicly lets the car run off of one battery until there is a extreme load ie:starting winches sound systems, that engages when neccicary so you dont put a large load on alternator when it isnt needed..

One battery running starter, ignition,.... basic functions Auxillary battery running accessory stuff....Winch, lights, amps, etc The idea being that if you run the aux battery down with other equipment, it still starts.....and if you happen to run the starter battery down you could "jump" from the aux. This does not double amperage or voltage though. |

Re: Dual battery setup question
mine i just ran each positive to the starter and grounded each to the block.
my old Tahoe i got a continuous running solenoid and ran the batteries to it. it isolated the batteries when off and charged both when running. also run a toggle switch to the inside and you can jump start your self from your second battery.

Re: Dual battery setup question
I have been running dual batteries in my '69 C-30 ramp truck for about 6 years now, and I have never had to replace the alternator.

Re: Dual battery setup question
I decided to buy an isolator. I got a Sure Power one (they actulally invented them). It basically, like previously stated, runs two batteries seperatly. One runs the normal vehicle functions, and one is for aftermarket stuff. The isolator detects which battery needs charged and automatically switches between the two to charge. The benefit is that you are not overtaxing the alternator and if you are parked (vehicle off, thus, shutting off one battery) you can use up all of the juice in one battery and still start the vehicle. I have been looking for this setup for a while, but I could only find $200 kits. My co-worker had one of these in his tool box, so I google'd it and found their website. I then had my parts department get me one from an aftermarket parts store locally. I went with a 120 amp model and it was only $60. I was going to do a 95 amp model which was only $45 but they did not have one locally.

Re: Dual battery setup question
I have never had good luck with isolators! If I was gonna seperate the two I would use a 200 amp relay or a continuous duty solenoid and just seperate the two when the key was off

Re: Dual battery setup question
In boats they run isolators and battery switches all the time with no harm to alternators

Re: Dual battery setup question
I put tons of big stereo's in boats and most have pergo switches but I have only seen 1 boat with an Isolator!
I put 10000 worth in a 47ft fountain at the beginning of last summer an I just just finished a 35 ft also.
