SECTION 6-ELECTRICAL SYSTEMS JAYCO TOWABLE
Connecting The Power Cord
Always test the external power source (i.e., the campsite power receptacle or electrical
box) with a ground monitor before connecting your power cord to it. If the ground monitor
indicates 'reverse polarity' or an 'open ground' DO NOT connect the power cord.
1. Turn “off” the load center main 120-volt circuit breaker.
2. Carefully extend the entire length of the power cord (approximately 25’-35’) from the
electric cable hatch to the external power source.
3. Plug the power cord into the receptacle. Be sure all the power cord prongs are
properly plugged into the receptacle.
4. Return to your recreation vehicle and turn “on” the load center main circuit breaker.
5. To help prevent power surges from damaging the connected loads, please follow
these instructions when hooking up to the external power source:
The shore line power cord should be unplugged when the recreation vehicle is left
unattended. If something would happen to the electrical system, this may help limit
potential damage.
When you are ready to leave, reverse the power cord connection process. Use care to
prevent damaging the power cord electrical connection pins when connecting or
disconnecting the shore line power cord. Grasp the plug to remove the power cord from the
outlet; do not unplug it by pulling on the cord.
Maintenance
Inspect the power cord for cuts, cracks and worn insulation. Have the power cord replaced
immediately if these symptoms are noticed.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power when the
shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be caused by operating the converter above its
maximum power output for an extended period of time, or by an obstruction to its
ventilation air flow. To reduce converter heat build, keep unnecessary 12-volt lights and
motors turned “off”. Keep the converter cooling fins and fan clear of obstructions.
