[DeTomaso] indicator light

[SOBill at aol.com]

David,
 
Just wire the light directly to the two wires of the fan. When the  fan gets 
12V so will the light. 
 
If you use an LED, which side of the LED you connect to 12V  matters. If the 
LED doesn't light, swap the leads. 
 
Common LEDs require an external resistor to operate on 12V. Radio  Shack 
sells LEDs which have a housing and built in resistor so they are easy to  mount 
and can operate directly on 12V.
 
Search >>>>>http://www.radioshack.com/ for  276-084.   $1.99        Red LED  
with Holder Model: 276-084  |  Catalog #: 276-084 
 
Have fun,

Hi  kids,

I need to have a little light to let me know when the cooling  fans  
come on (ford, but not pantera) . . . it seems one could just  take 12v  
off the fan to a light.  It also seems this is a fire  waiting to  
happen - do I need to take the power off the  relay???

Help please . . .

electronically challenged I  remain,

David in  Durango
