possibly jst - rcy ? ??
It's a standard radio controllers power connector crimp, but has an external barb, yours looks to have a blank reccess which is for a plastice external barb.
If you have a r/c model shop etc, take it there and ask.
If so you should also use the correct crimp tool on the 1.4mm gauge.
Very expensive tool, we use this pa09 crimp tool, only from japan but very good quality.
The whole crimp industry is a nightmare, i currently work with a company on speed controllers (esc) - we use 20 different types from 1mm to 10mm, some call that a plug or a recepticle - others call it a socket - the variation drives me mad.
TBH i would just fit a new yoke cable regardless of the $30 cost.
I think you are saying the white cable has snapped, not unusual and it is possible to repair the loom if desperate.
You can cut back the cable 50mm from the head crimp and 25mm from the side panel crimp and fit a new section, securely and carefully joining the wires, then soldering followed by a small piece of heatshrink, the cable must be silcone sheath and probably 10/01.
I have to do similar at times on up to 700vdc units, easy when you have all the correct equipment.
