Correct.  I also have Toby's keyless entry installed and it happens when I 
use the remote as well.  (Toby's system has been verified as working 
properly.)

Yes I have, and power is there.

I have already tested the solenoids independent of the module and both work 
great.


Here is a new development.  While verifying that the module itself was 
getting power, I also checked the capacitors.  While the system was 
"unlocked", the lock capacitor was holding at 12v, and the unlock capacitor 
was holding at .5v.  When I "locked" the system, the unlock capacitor was 
holding at 12v, and the lock capacitor was holding at .5v.  So when I went 
to unlock, the system responded and unlocked, however now both capacitors 
were holding at .5v.  Obviously, when I went to lock again, there was not 
enough standby power to activate.  The module is getting steady power at 
this time.  I am not an electrician, so I'm not sure why it's taking so long 
for the capacitors (which just got replaced because I thought the old ones 
were shot) to charge again.  They do eventually charge because I am able to 
lock/unlock again after some time.
