Will the direction of rotation of the idler motor indicate the direction of rotation of the spindle motor?
inside the control box, incoming line 1L1 connects to H1 on the control transformer, and it is jumpered to H3. Lead 1L3 is connected to H4 on the transformer, which is jumpered to H2.
That leaves 1L2 as the only line-in lead not connected to the transformer. That will be the lead that id connected to T3, the manufactured lead from the RPC ?
