Need more cold crank amps to turn a motor over, have 2 batteries, how to connect?
Need to use the power of two 750 cca batteries to turn over an engine, one isn't enough. How would I wire it up to get the amps but not any added voltage? Having a brain-free moment and can't think of how to do it...

You are describing a parallel wiring situation. Wire the positives together and then the negatives together. I'll try and find a picture to demonstrate. But this will keep the voltage the same but add the amps.

Thanks. 
Wasn't sure if it would increase voltage, if it doesn't then that's the setup I need and can use the F350's two batteries to handle this. Will try that this evening to get the monster turned over. Been sitting for awhile.
