Re: [Chrysler300] halogen lights and electricals

[Ray Jones <hurst300@xxxxxxxxxxx>]

Amperage can be a big problem in electrics, be they Automotive or 
anything else. Used in all modern cars, they can be adopted to our uses 
easily.
So, for those who do not understand what a relay is, here's how they 
work:
  To avoid having a big draw (amperage) go thru a switch and/or a 
harness, you add a relay. This uses a small amount of current from a 
switch to move a large amount of current to a motor or suchlike. The 
relay is wired to the Battery with heavy wire and then to the device 
that needs the power. When you turn on the switch, a wire from a switch 
carries a small amount of current to the relay which closes the contact 
between the Battery and the device, supplying a larger amount of 
current to do the work.

As an aside, Japanese vehicles use negative switching. The switch 
provides ground not power. This prevents the switch from burning up its 
contacts, and failing.

Down to 35 today, with sun. Going back up to 70's next week, so it's 
back into the garden.
It's getting time for y'all to be polishing up your rides for the 
Spring Meet! Be there, or be Square!
