Question about Bench Grinders
Have a bench grinder, came with out a switch there is 6 wires to connect to the switch Any help would be appreciated
2 wires are not needed to use they are the wires of an supression capacitor on the switch then there are 2 wires from your power cable and 2 that goes to your motor that 4 you only you have to use you can also connect the 2 wires from the s-capacitor with te wires on the motor together thats is how its also correct, (but best is to remove it because its only for suppression for FM ukw radio signals and everybody has DAB+ and the change to have short-circuit is reduced.

That entire older Buffalo line of grinders: N-10CB, B-8CB, B-6CB, bgbr-6cb all use the same push pull switch.Most of those grinders were dual-voltage with a starter capacitor and there are 6 wires connected to a 4 contact switch. The "Jet BGS8-076" grinder switch that is used by the older Buffalo's, Galaxy, Duracraft and TestRite grinders is no longer available. The good news is that there is a replacement switch from another manufacturer: "3030-9001 push pull switch for RDX grinders" from Wholesale Tool is a direct replacement. It has the same 4-screw contacts on the back and the same push-pull diamond pattern front plate.
There is a post on RidgidForum and on Yesterdaystractors that shows the proper connection for the 6 wires (in a 110Volt setup) The white and yellow go together on one post opposite them is a black and red. beneath the black\red is the other black and the other red is beneath the white\yellow.

Hi again, OK, Well since I don't have a wiring diagram and the colors don't help. I am also going to assume it is 110VAC. The larger wires are probably the run or primary, it you remember which ones were connected it will help with polarizing. ( getting it to run in the right direction as well as the start and primary working together). You can use the two terminal switch but you should use a three wire cord. Use the switch to break the neutral and ground the case. The connections should be as follows: Connection 1, would have one of the primaries and one of the starts to neutral. Connection 2, the other start to the relay. Connection 3, the coil side of the relay to the remaining primary. ( if the relay has two connections on one end and one on the other it would be the single) Connection 4, the 3rd position on the relay to hot. That is how a split phase is wired. You may find a simple wiring diagram on the net if you type split phase motor wiring diagram. Good Luck to you, this should Fixya!

Replacement should be simple. Just do a one for one hookup with the new part, after you unplug it first.
