Axles
Rubber torsion style axles are used on all
Jetstream tandem trailer units. They offer
outstanding ride and handling characteristics.
Load ratings for each axle are as follows:
Unit Type Load Rating
3000 3500 lb (1588 kg)
3600 6000 lb (2722 kg)
4200 7000 lb (3175 kg)
If a problem with an axle is suspect, contact
your Jetstream representative.
Trailer Breakaway System
System Check
1. Disconnect the trailer connector from the
tow vehicle.
2. Open the battery case (Figure 49) and
check the battery voltage using a voltme-
ter. The battery should be approximately
12V. If less than 12V, charge the battery.
Note the voltage before proceeding to the
next step.
3. Pull the lanyard (Figure 48) from the
breakaway switch and listen for the
engagement of the brakes. Recheck the
battery voltage. The voltage should be 1 or
more volts lower than the previous mea-
surement if the brakes are working. If the
brakes could not be heard or if there was
no change in voltage proceed to the next
step.
4. If the battery is properly charged, the
switch must be checked. With the lanyard
pin pulled from the switch, check for con-
tinuity of the switch by probing the two
wires with a continuity check function on
a digital multi-meter. If there is no conti-
nuity, replace the switch.
5. If there is continuity, a wiring problem
is likely the cause. Inspect the wiring
for poor connections or broken wire and
repair.
