jay: I have a number of progressive controllers older LED4 & LED5, they are no longer holding their programming for more than a day when the machines are off. Which component is the battery ? that holds the info...... |

knagl: I don't think I've seen one of those in person, but I'd take a close look at the green-wrapped circular thing -- could that be it? |

stayouttadabunker: I agree with Knagl...that green wrapped cell is a NEC 5.5V battery and it's positive (+) pole runs straight to the 1st leg of the 4 diodes and 100 ohm resistor. It's negative (-) pole runs right to the blue capacitor next to it. Upon looking at it some more...it just looks like a cap? Now you've got me wondering where is the battery too? Here's a link to a similar .22 farad 5.5v green thing on Mouser. They call it a "Super Capacitor"...>>> http://www.mouser.com/ProductDetail/Kemet/FS0H224ZF/?qs=%2fha2pyFadugLzN1S7KquHrj1JFtHwCBEAT9DriN6mzG%2f%2fJx6hHuJew%3d%3d |
