lightbars are thoroughly tested prior to shipment. However, should you encounter a problem
during installation or during the life of the product, follow the guide below for information on repair and trouble-
shooting. Additional information may be obtained from the factory technical help line at 314-426-2700 ext. 2131.
NO STROBE LIGHTS IN THE LIGHTBAR OPERATE - Check the following: 1) +12 VDC source connection for the control switch box
and any in line fuse 2) Connection of the RED and RED/BLK or RED/WHT wire at the control switch box 3) Check the 15 Amp ATO fuse
on each power supply. If the fuse is blown, replace it with another 15 Amp fuse and test the lightbar. If the fuse continues to blow, return
the power supply only, NOT the entire lightbar, to the factory for service. For instructions on power supply removal see the " Electronics
Module Removal " section of this manual.
Do not replace the fuse with one of a higher rating. This will damage the power supply and void all
warranties.
