Re: 1994 750 Vulcan Electical Issue
This is days after your question, so you may have already tried it, but here's my advice.
I wouldn't run it if the regulator/rectifier plug is damaged and there's no battery in the bike, but yes, you can push-start a Vulcan 750 without much problem. I've done it on numerous occasions since I've been having charging problems on my 2003 model. I can even push-start it by myself if it's flat ground or sloping downhill a little, when the engine is still warm from running (like at gas stops or poker run stops). I don't think it will work without a battery in the bike, but I haven't ever tried it. I've always had a weak battery in it at least.
If the wires get shorted out in the damaged R/R plug, you may end up screwing your whole charging system by trying to start it, so I wouldn't do it.
