PART NUMBER WW10221N
6 volt negative earth DC regulator
Important
- please read these instructions carefully prior to fi tting. This unit will be damaged if
connected with reverse polarity. Before connection please check your chassis earth polarity and make
sure you have the correct regulator for your earth polarity.
Please note the wiring instructions also require a 15 Amp fuse to be connected in the red wire. The
regulator will cause this fuse to blow if the battery is connected backwards. If the fuse blows, re-check
that the wiring and battery polarity are correct. Running the regulator with reverse polarity, even for a
short duration, will damage it beyond repair. If in doubt contact an expert for advice.
