Allow engine to cool before performing
troubleshooting maintenance. If necessary
use insulated pads and gloves. Hot engine
components will burn and cause injury to
personnel.
Remove all jewelry such as rings, dog tags,
bracelets, etc. If jewelry or tools contact
positive electrical circuits, a direct short
may result. Damage to equipment, injury or
death to personnel may occur.
Use jumperwire only between terminals indicated.
Failure to comply may result in damage to DDEC
components or wiring.
DDEC ECM connector terminals are easily
damaged. Use care when connecting and
disconnecting connectors.
