ps1 module question

[snoopy]

Have the yellow wire on module power cable hooked to yellow on my graph power cable. When graph is off the module power light stays lit up red. When graph is turned on it goes to green along with the other 2 lights on module. Is the power light on module suppose to STAY on red while graph is off?

Yes, the red wire of the module power cable should be connected to constant power. That is the red light. When you switch on the graph, the module "wakes" through the yellow wire.
