Battery Fuse
An in-line Battery Fuse has now been incorporated into this product. The fuse rating
is 2 Amp Anti-Surge. The fuse holder is spring loaded, therefore you should ensure
that the battery lead is not under tension in order to maintain a good connection

er together and twist anti-clockwise. Please ensure correct battery charge on comple-
tion of the installation and during each service visit.
