How can you bypass the battery warning light and a 1983 V45 Sabre you bought a new battery that does not use the sending unit no place to put it on the new batt just want the light on the dash off?

I have an 82 Sabre and solved this by removing the battery probe and inline resistor, it unplugs from the sending wire at a connector a couple of inches from the probe. Connect the sending wire to any positive wire, insulate the connection to avoid shorting the electrical system. I kept the old connector intact and saved probe in case some time I will want to reinstall the battery probe.
