I'm just going back looking for stuff on 6V batteries,wow, I didn't think there was so much to consider. I'm not going 12V no matter what,at least not in the near future so I'm not interested in any of that info.
I read about 6V batteries discharging at highway speeds ??? Why is this ?How to prevent it ?
My generator is a model 58 and I have a new delco regulator.(I'm just building this bike now).
I read about many 6V batterys being poor,and only harleys battery tender will charge Harleys batteries ,which many said are very poor quality batterys ,then I read about using batteries that run kids toys ,and home depot batterys (I'm not sure what battery that is).
I want to ride this bike and park my 91 springer,and would like it to be as dependable ,as I ride maybe 5000 miles this year .I read about 6V halgen headlites,led tailites to reduce voltage.Here in Alberta they have a daylite headlite law so it would be on when ever the bike is moving.
Then I read about using certain regulators ,some were electronic ,so as not to over charge the battery ,some of these batteries were the kids toy ones they were talking about. Then there was the subject about melting the armeratature if the battery goes dead,And then there was questions about gel,and /or Matt batteries (what ever they are)the there was the questions about ....I forget......I'm overloading my own battery with all this stuff to consider. Is there any volumes on this subject I could download ? My computer has only 40 GB so I could probably download one of the sets smaller volumes.

I just thought of somthing else,my big battery charger with 12V/6V charging capabillity puts out 15 amps 6V on low 40A on high. I guess this is far to much,so I got looking at an A/C adapter that says out put 7.5 volts dc at 1 amp.How would this work as a trickle charger??

neil

6 amps is not too much if you don't let the battery get too hot. or try to charge it in a bike with hot oil in the tank.

if you are not into that then get a 1 amp charger.

Neil,
The "6v discharge at highway speeds" only applies to the 3-brush 32E systems, its designed into it. Your '58 2-brush generator with a regulator will not have that problem. The only problem with a regulated 2-brush 6 volt system is overloading one that does not have a cooling fan mounted on it. They will generate all the power you want but they will also generate heat. As long as you're out on the highway in the wind you will probably never have a problem, city traffic in the summer heat might be a different story; turn off the spot lights!
