Don't use the MN with funds in it, there is no reason to open that up. Use your online "working" masternode. If your setup is relying on a masternode.conf file, do vote-many, if you're using a dash.conf file, do simply vote
Thanks, using vote instead of vote-many worked!
I have to use the MN with funds in it, as I am using a simple MN as per this fantastic guide ;+)

She meant that you can just use any empty wallet with the correct masternode dash.conf and vote without any risk to the 1000 coins. Not sure if there's official documentation on it.
