[TowerTalk] Rotor Brake Delay

[Ken Simpson, W8EK]

Hi Brian,

While that might be the simple circuit, this is a circuit board about 
2 inches square with four power diodes (1N4001 type), plus two 
additional diodes that might be 1N4148/1N914 type, a 100 uf 63 Volt 
cap that I can read, plus the unknown cap that is in 1000 pieces. 
There are also 4700 and 1000 ohm 1/2 W resistors and 68K and 100K 1/4 
W resistors.  So this circuit is a bit more complicated.

Two of the 1N4001 type diodes are shorted, as are both of the smaller 
diodes, and of course the one cap is VERY open, in 1000 pieces.

Certainly there is a schematic someplace!

I certainly would appreciate any help.

Thanks.

73,

Ken, W8EK
