hi Bill,
?
what's the power consumtion of the device? normaly not more than 100mA on idle state.
Is the 78L05 still alive? not too hot, 5V at output? The relays are powered directly from input 12V...
?

I forgot: You have to change the cells 00 and 01 for use with device cell 00 to 78 and cell 01 to 04 or 05
