Pump RUNNING Indication
"k" stands for thousand
"Charlie J" wrote in message ... Thanks to both of you...Meindert-I don't understand the notation "2k2" or "4k7" in your post. Would you please explain? 73- Charlie One caveat: if the .33 resistor or fusistor blows, you get 12V through 100 Ohm at the base of the transistor. This will produce a current of 120mA at the base, which will kill the transistor. A base resistor of 2k2 to 4k7 will do the trick. |
