So I am out of ideas at this point on trying to find a solid state reg/rec, one that will work with a lithium ion battery (antigravity 8cell). I have contacted Ricks Motorsport Electrics they sent me a link to an OEM style reg/rec part number 10-100. Yesterday I spoke to tech support over at Antigravity batteries the gentleman seemed to think that the reg/rec set point from Ricks was a little high at 14.87DCV, but he did recommend checking out cycleelectricinc.com. Upon visiting their site I was unable to find what I needed. Lastly, I have also contacted the guys at Revival Cycles they replied with this
"The charging system on your bike is a field excited system and that means there are two types of reg/recs for that style of charging system. There is a type A and a type B, the type A have one of the field coil brushes connected to +12V and then the regulator controls the field coil with the ground connection, and type B has one filed coil brush connected to ground, and the regulator controls the power supply to the coil. I have looked up a diagram for your bike, but this detail is not clear. It appears to be a type B in which case you would need a ricks motorsport electrics 10-504 reg/rec. But, my recollection is that the hondas were typically type A charging systems which use the ricks part number 10-503.
If you can find a more detailed diagram I can take another look, but this information is probably well discussed on the forums. Alternatively you could test the setup on your bike, if both wires for the field coil are isolated from ground, then you could connect it to work with either style. But if you check and one of the field coil wires has a path to ground then you will need to go with the Type B.
The reg/rec just needs to keep the voltage between 6V and 15V and that isn't too difficult. But its the battery that you choose that really affects the reg/rec requirements. If you want to use a modern LiFePO4 battery then the only ones we've found that work with the new style batteries are the reg/rec's from Ricks.
If you are using standard lead acid batteries, then you can use any reg/rec that is specified for your bike, and you shouldn't have any problems."
While that's a very detailed and precise reply, I'm not that savvy when it comes to this kind of lingo. Essentially I'm more lost now than I was when I started my quest for a new solid state reg/rec. it would be great if you fine folks could shed some light on the subject. Basically where can I buy what I need? This is the last bit I need to complete my electric part of the rebuild. Thank you for taking time to read and help.
