Shindengen (open type SCR) Regulator Installation MK II

My Commando e start would not care for 12.26 volts. A low battery is a great way to wreck a sprag, according to Hinckley Triumph.

No serious problem though, just put it on the battery charger for awhile before starting.

I don't think the parasitic loss is a big deal, nor is the nonexistent heating problem with shunting regs.
Even so, the less parasitic loss the better and zero would be ideal.

Not to worry, my MK II Commando doesn't have an electric foot!

Where and how does one measure for the Parasitic draw?

Remove either the + or - connection(s) to the battery and put an ammeter between that battery terminal and the lead(s) removed. If an analog meter, use the lowest range on the ammeter that does not peg it (start high and keep turning lower). If using a digital and there is only one range, use it.
 
Got it, Thanks
Seems like one could pull the fuse and measure across the leads?
Norton would be simple.
Modern day bikes, not so much.

Apparently it doesn't make a diff using 'Hot' or Ground.
I think I would be apt to use ground, to prevent unwanted shorting.
Cool, something new to play with..

Yes, you could pull the fuse and measure across the leads. No, it make no different + or -. If the meter goes backwards, just swap the meter leads.

I should have also said that if there are multiple connections to the battery where the fuse connects (normally the - terminal) you should not do the fuse. Some wire the regulator directly to the battery, so the fuse is not in line with the regulator.
