No, it means you have the probes reversed. Ignore the middle three, and
measure on the 20 V scale. You should really download a service manual.
Here's the relevant bit:
Additional Procedures Battery Verification - 21
1 Set a voltmeter to the 20
volts DC scale. Touch the
positive probe of the
voltmeter to the
positive terminal and the
negative probe to the
negative terminal.
2 If the reading is not 12
volts, recharge the
battery. If the reading
remains below 6 volts,
replace the battery.
