That shouldn't be a problem: as soon as you connect the two, assuming the wire gauge is large enough, the voltages will immediately begin to equalize - and given that the charged battery voltage will be dropping while the discharged one is rising, the current flow between the two will shortly drop to a relatively low level. Of course, if (e.g.) the engine is running at the time, then there will be essentially zero current between the two anyway. > Small gauge wire at the proper length with high temperature > insulation might limit the current to an acceptable level. In my opinion, small gauge wire doesn't belong anywhere near a charging circuit: please consider what would happen to that wire if the battery was discharged and you fed it the full alternator output. FWIW, I often use my alternator as a welder, and it happily turns 1/8" 'wire' (a.k.a. welding rod) into a red-hot glowing liquid. -- * Ben Okopnik * Editor-in-Chief, Linux Gazette * http://LinuxGazette.NET * _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
