My Yager/Dink 200i, which gets anyway a lot of care, was asking for more.
For a couple of days I suspected my scoot not to deliver what's supposed to, a proper voltage into its battery (new LiFePo4- 9amp).
The generator delivered on all three yellow/now brownish cables at 4000 rpm, about 55VAC, evenly on all of them, measured 1-2, 2-3, 3-1.
So the stator seems to be healthy.
Only suspect now was my rectifier/ regulator. Upon measuring it showed normal 14+VDC feeding into battery.
Nothing irregular IMO, until I touched this 3pole connector between stator and regulator, burning hot.
Opened it, and saw the cause.
(pls see pics)
-one cable within this plug had due to overheating "friendly fire" with its neighbour, melted through its separation and caused this intermitting failure
-since this plug would be on order, I decided to do the "direct" solution to solve this prob
-some layers of shrink-tube to avoid fireworks do the trick
-DC voltage at battery, without lights, lights on and at dashboard with brakelights
Its a common fault on cycles and cars, as many owners complain. For there are from 50-100VAC running throught this undersized plug, vibrations loosen those little prongs and firework starts.
This cables AND regulator are getting pretty warm without sparking too, so its worth to help to keep it "firefree".
