Overcharging battery (2019)

Been running a Shorai on my Commando for 7-8 years, originally with the Lucas rectifier/Zener and, a few years later, with an Alton E-start/Podtronics. Shorai has been fine with both systems and I am still using the same Shorai battery that I originally installed.

Frankly, I have never had a moto battery on any bike last 3 years let alone twice that... ;)
hmmm I wonder if my zener is failing then or on its way out...
 
I live in asheville! And what rally? I need more places to go aside from the mountains. I just moved here a couple years ago!

The rally was about 4 years ago in July. It was a national rally for the INOA (Int'l Norton Owners Association) and sponsored by the local chapter, NCNO (North Carolina Norton Owners). Was a great rally. The rally location rotates erratically around the USA and Canada every year.
Asheville is a great place to live. My wife and I were there for the rally and stayed up on Black Mountain. Had some good brew at a pub downtown more than once.

Thats awesome! I used to live 10 min from black mnt. I almost joined the inoa when I lived in Washington DC. I really should join my local chapter I'm sure they do some good riding out here! Thank you for all the help I'm still fairly new to really getting to know these bikes. But I'm excited to have two different examples of them. My 72 roadster is kinda bare bones and updated. Where as my 1970s is all original. I'm restoring the paint super slowing wet sanding the rattle can someone put on it... Its a painfully slow process but that bike has the original silver tail piece. The original plasic nuts on the halo ring. Original wiring harness. One of the members helped me with original exhaust. I have to do the bike justice. They just ride so well and so much more powerful than any of the other British bike. I really enjoy working on them and riding them. So thank you for all the help!!
 
I am up in shady valley Tn about 80 miles from asheville. i do a fair amount of riding around here along with some norton work. we should hook up one sunday for a ride.

I have started my Commando after fitting a SH775 reg/rec , and sparkbright led voltage monitor , the battery is a Motobat 9 AH,and three phase new Lucas stator, with the headlight off after a short ride the led is flashing red and green (said overcharge , according to spark bright it's over 15.2 volt) , with lights on , it happens over 3000 rpm, tested at home with the Fluke multimeter confirm high voltage , fit another SH775 (from another cdo I have ) same voltage ..............!! could a bad battery do this or what else , cannot imagine two bad reg/rec , but ??
 
No, battery won't affect the regulator's regulation point. Where did you get the regulators?
 
Those are real shinden gen sh775 , from Polaris ! and if the shunt one FH can be easily tested the sh series one cannot (at least at my electrician level) !!

How have you connected the SparkBright? The maker recommends a direct connect to the batter terminals and not ot place it on a circuit that gets switched on with ign. This is because the LED is quite sensitive to voltage spikes which will occur on circuits for the ign/lighting etc. There is such little current draw (milliamps) from the LED there's no worry about leaving it always on when the bike is not running...a good battery will be fine for at least a month or two without a trickle charge with this LED on.

I will check tomorrow , thanks for your reply ! though remaining the fact that the Fluke said over 15 volts ..............
 
Update .........so, I changed the SH 775 for a FH 12 AA, same problem the spark bright quick flash red/green (= overcharging), fed up tht day as I should go the 40th french Norton club meeting/anniversary (300 miles trip ) , so I took my Atlas (Joe hunt mag) , fine weather , nice people ( 105 drivers ), back yesterday evening , this morning tried the Cdo and tested it again BUT with another battery , everything OK , so a bad battery can cause overcharging (that one was a recent Motobat )..............that 's all folks !
