I have an old turret lathe, it has a dual speed motor operated by an old Square-D NEMA1 contactor, which have failed.
The original contactor (starter) has 9 contacts for motor leads.
Low speed it connects L1 L2 & L3 directly to T1,T2 & T3 ..
High speed it connects L1,L2 & L3 to T4,T5, & T6 AND Connects T1, T2 & T3 all together for a STAR run.
I cannot seem to find a contactor like this, Any ideas on where to start ??
What is the standard procedure to use when working on these antique machines ?
