nector (X10.1 and X10.2)
• If the connection is OK, proceed with
step 11.
• If there is a problem with the connection,
repair the connection and start over.
• If the resistance of bleeder is greater
than 20 ohm or less than 10 ohm, replace
the bleeder. See Replacing the break
resistor bleeder on page 284.
Check the bleeder connection at
X10.
