My PreCor C846 recumbent bike won't turn on. I installed a new battery and purchased a new power cord. Is there something else I should be checking?

You can test the HR grips to see if the wiring is good all the way from the contact grips to the upper board by doing a test with your meter. Get a meter that can test fuses and beeps if the fuse is good.
disconnect the 4 pin brown connector at the console board, on one side will be some metal contacts.
Touch one end of the meter lead to one wire and the other to the HR contact plate on the handlebar. try all the contact plates on the handle bar until it beeps, then move the lead to the next wire and repeat until all contact plates beep. It all of them beep then your wiring is ok and the problem is in the Heart Rate board in the console or the connection point on the board.
Let me know how it turns out.
