Been there done that. Funny a year ago when I was calling SMBw asking for a BlueSea Separator they didn't know what I was talking about.
Incidentally I don't think you should jump the separator terminals with anything less than a jumper cable or jumper sized cable wire (a good sized bolt or wrench will work in a pinch), basically the amp draw across the terminals is more than most spare wires could take- meaning they might melt or burn.
You can also remove one wire and attach it to the other side for a longer term "fix", but all of these are with live voltage so care should be taken.
Glad you're up. My opinion is run open (no separator) until you can head to SMBw and get that BlueSea. It's much nicer. Make sure they install the switch for it too.
