I have installed a mo.lock RFID ignition switch as with the CNW estart I have put on there isnt room for what has always been a non-standard install location for the stock ignition switch.
It works fine when kicking the bike but, it cuts out after a quick tap with the estart and looks like I need one of these (which GTiller and I thought I wouldn't need due to the having the 2MC).
The mo.lock backup capacitor is used to level short-term voltage drops to the main relay.
If cranking the engine via the electrical starter is slow and resistive, very large single cylinder capacities or high compressions can cause significant voltage drops. Implementing a backup capacitor prevents short-term voltage drops from de-energizing the main relay.
In NZ, you can get these shipped from AUS for $45-66!!! It appears to be a small electrolytic capacitor - probably of the $1.50 type. I have asked motogadget what the spec is, but they are closed moving their shop location and I guess they would rather sell me a cap.
From looking online, i cant find any specific info - just info on caps for compressors or electric motors. This one has calcs that get me to about a 15uF cap (assuming 1.4kw for the starter, which I also found via google).
Does a 22uF electrolytic sound right to those of you who know more about this stuff than I do? What min VDC for the cap - 25, 50, 63? RB, Low ESR, Bipolar?
Schematic below - note this sits behind a 1A fuse.
