General Tips To Prolong Equipment Lighting
!-- CONTENT HERE -->
NEVER USE A TEST PROBE TO PIERCE WIRE INSULATION
When troubleshooting lighting complaints never
pierce the wire insulation
Wicking action takes place which causes moisture
to travel along the wire strands and corrode critical connections along the complete
connection - "salt creep".
If probing a harness or wire is unavoidable, make
sure the puncture is properly sealed - understand that the Ultra-Blue-Seal system is
a modularly sealed system that must not be cut into - especially for warranty purposes.
Testing should take place at each termination point along the main, rear sill, jumpers,
pigtails and lamp itself. Replacement then does not need to be the whole system, but
simply the damaged extension area.
TO CORRECT VOLTAGE PROBLEMS DISCOVER THE REAL CAUSE
Under-voltage often is caused by poor electrical
connections. To correct under-voltage or illumination problems, dont just turn up
the voltage, find out what caused the under-voltage problem.
Over-voltage is causes major damage to lamps and
MANY DISCARDED LAMPS ARE STILL
IN GOOD CONDITION
Do not simply "assume" when solving lamp
problems - explore all avenues to make sure you are identifying the true source of a
problem. Make sure you are not simply fixing a symptom of a greater problem.
First, test with either a meter, power supply, or
battery. Our male and female tester are perfect for this (87810 and 87820).
Then if you desire, open the lens on a discarded
lamp and examine the bulb. It will help tell you what failed. For example:
- A bulb with stretched or broken filaments was
subjected to heavy vibration.
- A yellowish, whitish of bluish glaze on the bulb
indicates a rupture in the bulb glass envelope and a possible leak.
- A dark, metallic finish indicates old age.
- A black, sooty bulb indicates a poor seal in the
- Test all lamps one time before you discard them.
General findings show that up to 40% of all lamps sent back are still in good operating
condition. The ones that arent working can be turned over to your lamp supplier.
ALL LAMPS WILL LAST LONGER IF
THEY RUN COOL
Dirt on lenses increases the heat, so keep them as
clean as possible. Other people can see your rig, and that is one of the purposes of the
lighting system (besides safety) - to be seen.
Heat is one of the most damaging conditions to a
standard incandescent bulb, right up to a cluster of LEDs, which can also be damaged by
heat. For this reason the Grote 4" LED offers significant heat benefits against the
competitors plastic housing as the anodized aluminum dissipates the heat into the trailer
All lighting must breathe to eliminate the damage
from heat build-up and thus shortening of bulb/lamp life.
TREAT THE ELECTRICAL SYSTEM AS
YOU WOULD THE CHASSIS
Lubricate sockets, pigtails, battery terminals and
connections with Ultra-Seal Sealant (99170) "nonconductive" anti-corrosion compound. Use the offered
Grote small tube of grease for lubricant.
The purpose of the sealant is to totally
encapsulate and protect against corrosion and water.
Do not use sodium-based greases. Sodium will
emulsify if it ever comes in contact with water.
INSPECT FOR IMPROPER GROUND
This is a major cause of lamp failure, especially
when the trailer is used for a ground.
When lamps are grounded through the lamp housing,
make sure there is a clean connection (ie. metal to metal).
Also, a fifth wheel ground strap may be used for
added protection on the chassis ground system.
LOOK FOR LOOSE, BARE OR
UNSUPPORTED WIRE AND FIXTURES
Harnesses an wiring should be on the underside of
top frame members rather than on the bottom where dirt and road splash collect.
ALWAYS REPLACE WIRING TRAILER
LIGHT CABLES AND HARNESSES WITH AN EQUAL OR HEAVIER GAUGE OF WIRE
(from original specifications)
If you dont, you may cause unnecessary
problems. See our catalogue for additional wire gauge information on specification. This
product and process mentality provides for proper gauging.
ON OLDER TRUCKS, YOU SHOULD
NEVER CRANK THE TRUCK WHEN ANY LIGHTS OR ACCESSORIES ARE ON
Also, never leave markers/clearance and hazard
lights on when parked against a dock. Melted lenses are a sure sign that the vehicle has
been parked against the dock while the lights were on.
Always remember that the trend is towards
reduction of power consumption, and voltage surges are extremely damaging to wiring or
INSPECT THE GROMMETS THAT
HOUSE THE LAMPS
As the grommets age, they eventually will
deteriorate from sunlight, ozone and harmful chemicals.
New grommets restore shock protection, security
and improves appearance.
