Nocturnal Electrical Leech

Mosfet 3 phase to the rescue from Nibor, used but good off a 900ie. Snipped spare yellow and soldered and clamped the other two. Soldered and clamped the negative wires to a smaller type earth lead I had laying around. Bolted it to the frame. Ran the power wire to the loom connection. Getting good voltage.
Used an alloy plate for a conversion bracket/heat sink with alloy spacers so the reg cleared the head stem frame tubes.

Thanks guys.

Only dropped •02 - •03 V overnight as it settled after a quick charge. Sits around 12.9V and charges at 13 with lights on and 14 with lights off at 2500-3000 rpm. Not bad.

So I have checked discharge rates over a few 24 hr periods. With the replacement reg and used but good Motobat battery, I'm seeing a discharge rate of 0.01-0.02 V over 24hrs. How does that sound? At that rate the battery would have lost 1V in 50-100 days depending on temp conditions and consistent discharge rates. It compares well to a discharge rate of 0.2- 0.5V over 24 hrs with the leaky reg. Not too bad for a used battery (which will get them out of trouble until they save up for a new one).
I guess anyone not charging a battery over a 3 month period is keeping the battery mfrs in business. The exception would be a Lithium battery I guess.

Sounds great.  See what happens over a few days.  Some of the .01-.02 volts you are loosing is probably just a bit of surface charge, or even change in temperature..
