I need some advise on installing a new diode board on my kohler 6.5cz generator. To get the old board out I had to unsolder the + and -connectors from the board. I was assuming I would just re-solder the connectors to the new board, but it appears that the new board has small round metal pieces that are threaded on the backside of the board. Can I simply solder the connectors to these round metal pieces or should I try and find a small screw/connector to fit in this hole and forego the solder?
