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.

Questions and answers
But how do you wire it to a Positive earth. They sent a 6volt Positive regulator. Not instruction on how to wire it.
You do not wire the WASSELL WW10221N to a positive earth. The WW10221N is a 6-volt negative earth DC regulator and is polarized for negative earth only. Connecting it to a positive earth system or reversing polarity will damage the unit beyond repair.
