[Elecraft] OT: 2017 Chevy Silverado 1500 power outlets

Tue Jun 27 14:57:09 EDT 2017

See my detailed response...  Original article is RIDDLED with inaccuracy
and fantasy scenarios that simply are not part of modern automotive
electrical engineering.

You build your stuff any way you want it...  I'll do the same...

I understand that you relied upon the article and the author as a basis
for making your OP....  doesn't make it any less inaccurate.

You simply CANNOT make absolute statements like that without AT LEAST
qualifying the EXCEPTIONS to the "God says..." absolute.  <grin>

73...  Apologize if my initial reaction torqued you off.  Been spark
chasing all my life from race cars to helicopters...  Certain hot
buttons set me off.... this is one of them.
