Sparx charging system

Well I hooked up my Sparx and I am still not charging. I am almost sure that the battery is at fault because of what has been said about how important the initial charging procedures for the batteries are for the Sparx system to work. I can get about 13.8 volts across the battery terminals if I rev the snot out of the bike, but at idle the volts just keep dropping.

air gap set
black to battery ground
red to battery positive through a 20 amp fuse (fuse good)
three wires from reg/rec to the stator assembly

aybe I will just buy another battery. I am running a boyer, led taillight, headlight, no signals, and kick only. I am using the three phase Sparx......what is the smallest battery that I could use?

Thanks Dave

you bout the same as mine only im running petes pointless, I put in a new yuasa and charged according to manufactures specs, Id bet its the battery, If you got it from 650central Id just ask mike on minumum size battery. Youll dig it when your upNrunning.

Well I recharged my battery again and have been riding it for a good longtime today and everything seems ok. I will check terminal voltage tomorrow. I have my seat bolted down and am too lazy today to unbolt and check the battery volts. I think that perhaps the battery was just a bit flat.
