WARNING! TO PREVENT FIRE:

Fuse Holder.
If the wire inside the Fuse is broken
the Fuse needs to be replaced,
otherwise insert the Fuse back into the
Holder and proceed to the next step.
2. If the Defroster’s Fuse was not blown,
connect another 12 VDC device to the
12 V auxiliary power outlet to check it.

the Defroster serviced by
a qualified technician.
b. If the receptacle does not work,
DO NOT USE THIS DEFROSTER
