Wow!
Once again this list is overwelming with GREAT advice. Although some of you
scare me. I work in the nuclear industry and wonder if any of you might be
with the NRC. I may regret it later, but I do not intend to run redundant
fans or rendundant switches. At least with the Tiger, the consequences
aren't quite as severe.
The thermostatic switch I'm using is designed to be tie-wrapped to the upper
radiator hose. I intend to tie-wrap it to the lower hose at the radiator
water neck. I want a low profile installation. My radiator is a Reisentz
work of art and I wouldn't let anything touch it. I even hard mounted the
fan. What I'm really wondering is: Does anyone see a reason NOT to use the
small lead off the starter relay to tap my power? It is only hot with the
iginition switch on.
Thanks again everyone,
Mark
