Sample Shop Voltage Measurements
The following tables contain some “real world” shop voltage measurements to help you recognize what
“normal” looks like. All voltage values were measured with the black (Negative) voltmeter lead connected to
the main battery negative unless otherwise specied. Most outputs were turned on using the Service/Output
test function. Machine battery voltage at time of testing was 37.25V.
