Inspect The Electrical Wiring - Genie GTH-636 Maintenance Manual

Maintenance Manual
Quarterly Maintenance Procedures
9 Check the ambient air temperature and adjust
the specific gravity reading for each cell as
follows:
• Add 0.004 to the reading of each cell for
every 10° F / 5.5° C above 80° F / 26.7° C.
• Subtract 0.004 from the reading of each cell
for every 10° F / 5.5° C below 80° F / 26.7°
C.
Result: All battery cells display a specific
gravity of 1.277 or greater. The battery is fully
charged. Proceed to step 10.
Result: One or more battery cells display a
specific gravity from 1.218 to 1.269. The
battery is still usable, but at a lower
performance. The battery will need to be
recharged more often. Proceed to step 10.
Result: One or more battery cells display a
specific gravity from 1.217 to 1.173. The
battery is approaching the end of it's life.
Proceed to step 10.
Result: The difference in specific gravity
readings between cells is greater than 0.1 OR
the specific gravity of one or more cells is less
than 1.177. Replace the battery.
10 Check the battery acid level. If needed,
replenish with distilled water to 1/8 inch / 3 mm
below the bottom of the battery fill tube. Do not
overfill.
11 Install the vent caps and neutralize any
electrolyte that may have spilled.

Q-3 Q-3 Ins pect the Electrical Wiring

Inspect the Electrical Wiring

Genie specifications require that this procedure be
performed quarterly.
Maintaining electrical wiring in good condition is
essential to safe operation and good machine
performance. Failure to find and replace burnt,
chafed, corroded or pinched wires could result in
unsafe operating conditions and may cause
component damage.
1 Inspect the following areas for burnt, chafed,
corroded and loose wires:
• Inside of the operator's compartment
• Underside of the chassis
• Inside engine compartment
2 Inspect for a lite, even coating of dielectric
grease in the following locations:
• All harness connectors
Note: Do not apply excessive amounts of dielectric
grease to harness connectors, pins or sockets.
Note: Do not apply dielectric grease to a engine
ECU/ECM or engine harness connectors.
3 Start the engine and raise the boom so there
is enough room to access and remove all the
covers attached to the chassis.
4 Attach a lifting strap from an overhead crane
to the boom. Support the boom. Do not apply
any lifting pressure.

Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
