I removed brittle wiring from a prewar 763E Lionel scale Hudson and now cannot rewire it correctly. Neither generic diagrams nor the pictures I took before desoldering are of any help.The Lionel corp. sent a diagram of their current electronic scale version which of course was of no help stating their archives contain no hits on the prewar version. I'm not a novice with regard to how electric motors work but I'm at a loss and need help.
Regarding the prior post looking for meter wiring, do volt meters in parallel and ammeters in series. The All Electronics corp at www.allelectronics.com has AC Ammeters & AC ammeters suitable for low voltage application at an affordable price.
