Hi @Divine_Cutler, the values for votes, if I’m not mistaken are 0 and 1.
In the case of a single node replica set, since there is only a single node the vote count would need to be set at 1. Changing the vote count, even if it could be greater than 1, wouldn’t have any impact as it’s the only node that can vote. If the machine is running it’s automatically the primary node. If it’s down, well then it doesn’t matter how many votes it gets. 
While a single node replica set might be fine for development purposes, it is strongly cautioned against putting that into production.
What are you trying to accomplish with having a single node replica set?
