Thing is, I have a RR501 (two, in fact) sitting around doing nothing.

I'm not looking to go out and buy an appliance module...I'm trying to

If I can't find the steps to modify the RR501, I'll just go with the
nightlight solution, another item that I have lying around doing nothing.

Thanks anyway!

I might try removing the 220K R44 which appears to be the sense
resistor. *I don't know if this would cause other problems. * For all I
know, it might need the feedback that the module is off or on in order
to hold the relay, or something crazy like that. *That said, *I did a

the sense current messing with CFLs or LED lights, I clipped one end of
the resistor in the sense path and it worked. *Of course, heed all the
danger warnings you read about working in X10 modules.

Thanks!

I had already found the mods that you are talking about, but since
they didn't apply to the RR501, I didn't want to try them.

OK, so here's what happened last night:

As a reminder, a couple of nights ago, I ran a test with the RR501,
the shop light and a lamp with an incandescent bulb. The setup was as
follows:

RR501 plugged into an ungrounded receptacle, a 3-to-2 ground adapter
plugged into the RR501, a 1-receptacle-to-3-receptacle 3 prong
expander block plugged into the ground adapter and the 3-prong plug
for the shop light and 2 prong plug for the incandescent lamp plugged
into the expander block.

This set up worked fine. Both lights came on when the RR501 received
the single to turn on and the shop light did not re-light after the
RR501 received the single to turn off. If I removed the incandescent
lamp, the shop light would relight.

Now last night, I tried this set up:

Before plugging the RR501 into the ungrounded receptacle I plugged a 1-
receptacle-to-3-receptacle *2* prong expander block into the RR501. I
plugged the 3-to-2 ground adapter into one of the receptacles on the
block and then plugged the shop light into the adapter. Next, I
plugged a switched 7W night light into another receptacle on the
block, making sure the switch was set to On.

Finally, I plugged to the RR501 into the ungrounded receptacle. As
soon as I plugged the RR501 in, the shop light attempted to start and
the bulb in the night popped (loudly) and turned black.

I unplugged the RR501 and went upstairs to watch TV.
