RE: (ET) Using Homelite appliances on Elec-Trak

["Elie, Larry \(L.D.\)" <lelie ford com>]

No, I really mean in series.  You close and open the circuit with the 
switch of the tool.  As far 
as how the voltage is shared; yes, it changes with the resistance.  If the 
tool resistance doubles 
(probably hotter than it can run) than the bulb gets more current because 
it's voltage is higher.  
But there is only 36V available, and that isn't going to burn out a 110V 
light bulb.  BTW, this is 
an old technique and used all the time in the lab.

I don't think this will work.  The problem is that the current the tool 
uses 
varies with the load.  Drop the bar into a big branch and the light bulb 
will 
brighten, maybe even enough to burn out, and the motor will just lug or 
stall.

If you don't want to tap the pack, you'll need some kind of DC:DC 
converter, 
methinks.
