I know them as 'Japan Solderless Terminals' . ( Manufacturer )DaveCPC-Farnell search for 'JST'https://cpc.farnell.com/w/search/prl/results?brand=jst-japan-solderless-terminals
Awhile back reference was made to JST Connectors. It is my understanding this means "Japanese Standard Terminal, and does not specify one particular size of terminal, rather a whole set of them. Am I correct?
BTW, I noticed the crimping tool at that source for only 300Euros. Better get a couple at that price. Or go to the local auto parts store and get one for $12.00.
If you look at the cross section drawing, you will see the rotor arm receives sparks from two different sources.
