Bridgeport milling machine wiring diagram

Hello, does anyone have a copy of the early Bridgeport wiring diagram they could share with me please?

My machine is dated 1969, it is the J head with 2 speed motor. The machine is new to me, when I looked inside the electrical panel on the side a couple of the wires are unmarked and hanging disconnected so I'd like to find out where they are meant to go and make sure it's safe before I power it up.

All of the wiring diagrams I can find online are for later 1970s machines with the larger electronics box on the side with the Erskine control unit.

Thanks

Are these the late ones?

A bridgeport users website would probbly be easier

Yes those are the later ones unfortunately, thanks for posting though!

I have two PDF versions of an older wiring diagram for a machine fitted with the large, gearbox type, X axis feed with start - stop button housing integrated into the main machine castings. Single speed motor unfortunately.

If you think they might be useful PM me your E-Mail and I will send them over.

As I recall matters I created the first one from a very rough photocopy around 20 - 25 years ago to help fix a friends machine. We got it going so I guess it might be about right! Some years later I had to replace a contactor and, presumably, produced an amended diagram.

Revolting colours unfortunately. Something went funny during migrations between computers an programs over the years.

All sorted now, thanks to Clive for helping me with a diagram.

Good to see another success on the forum, thanks for letting us know.
