Why is it needed?
I plan to install a voltmeter on my 2005 VN750. It'a 2 1/6" Vision #
332-103 from egauges.com. The instructions on Starman's Kawasaki
Vulcan 750 Page - Tech and Mods recommends a relay or a manual
switch. When I turn my bike's ignition switch off, everything shuts
off, engine, headlights, running lights, brake light, etc. The
instructions with the gauge does not mention anything about a relay,
they show the gauge wired after the ignition switch. So, if the
whole electrical system goes out when I turn the ignition off, why
do I need a relay or another manual switch (toggle switch)?
Thanks for the input folks, and I hope that you all had great
