Volks I'm trying to find out the range of behaviors for the late Westy water-level circuits. Anyone wants to help, I'd like to know three sets of things: 1) what are the resistance readings on your float sender when unplugged (middle and bottom -- top should be very low resistance). 2) what is the behavior of your lights. 3) if you're willing and able -- substitute a one megohm pot (RS 271-211 or similar) for the sender, wiring to middle and one end terminal. Measure the resistance at each transition point where a light turns on or off (unfortunately you have to unhook the pot to measure the resistance, b/c the ohmmeter and the LED panel will fight with each other). Oh yeah 4) the year of your beast. I'm hoping to find a pattern of component drift that will explain the rumored "early and often" failures of this system. It's really a very simple system and ought to work indefinitely. thanks david David Beierl - dbeierl@ibm.net |
