[Yaesu] FT-980 battery back up problem

[Dr. Gerald N. Johnson]

Wires broken more than one place (the end)? backwards polarity? Start 
tracing with the voltmeter with power of to see that power is getting 
through the wires. New AA batteries should do 1.54 volts each, so you 
should see 3.08 volts, not short of 3 volts.
