From this and your questions below, sounds like some of the manual pages 
for the E-20 would help.  They cover the basic logic and the PC 
board.  I'll email you some of the key ones from the electrical section 
directly so as not to spam everyone on the list with large files (2 files x 
1.5 MB).  Anyone else interested, drop me a line and I'll send them your way.

The connector there should have a couple of jumpers on the charger's 
plug.  Going by the marked pin numbers, the connector on the timer is as 
follows:

1 - White from power cord
2 - To timer motor
3-5 - Not used
6 - Green from power cord
7 - To timer motor
8 - Black from power cord via timer switch

On the charger side the plug just extracts the three wires from the power 
cord and has jumpers between pins 1 & 2 and pins 7 & 8.  These jumpers 
allow the timer motor to get power.
