RVTI Review PDI DC Electrical Systems

During the first step in performing PDI on electrical systems, safe work practices include which of the following? (Choose all that apply.)

• safety glasses

• footwear

• gloves

• no loose jewelry

Place the steps for the simple series battery bank in the correct order.

• configure batteries on test bench

• record amperage

• connect distribution system to the battery bank

• record voltage

• interconnect batteries

Place the steps for the series/parallel battery bank in the correct order.

• connect two sets of 6V batteries in a series

• connect distribution system to the battery bank

• connect each set of 6V batteries in parallel

• record voltage, then amperage

• configure batteries on test bench

Place the steps for a parallel battery bank in the correct order.

• connect distribution system to the battery bank

• configure batteries on test bench

• record voltage

• connect two 12V batteries in parallel

• record amperage

When connecting the distribution system to the battery bank, connect the batteries...

• positive to positive, negative to negative

• positive to negative, negative to positive

• in parallel

• in series

Match the following requirements for creating battery banks.

• two 12V batteries

• parallel

• no requirement

• simple series

• two sets of 6V batteries

• series/parallel

When constructing a battery bank, the first step is always...

• tightening connections

• to configure batteries on a test bench

• checking the connections

• to configure batteries on a test bench, with batteries oriented positive and negative

The first step for Power Converter PDI is to...

• plug the coach into AC power source

• plug the coach into DC power source

• verify there is a power source

• measure DC voltage

After measuring DC voltage at the converter and at the battery, you notice there is a voltage drop. Your next step is...

• contacting a Level 2 technician

• Documenting

• Unplugging the coach from the power source

• Rechecking

When completing the Alternator PDI, measure DC voltage at the...

• coach battery bank

• chassis battery bank

• converter

• charge controller output
