I'm seeing a lot of new posts on this thread, but I've not seen anyone test blairc's 21/07/00 theory that the the alarm or keyless-locks may be sensing the empeg's current draw. I have no idea why they should do that, except maybe it has something to do with a circuit that disables the ignition when the car is locked up. If any of the tests below cause the alarm or lock to fail, then try connecting the constant voltage line directly to the the battery.
1) Does the system work if the interior lights are left on?
2) If so, does the system still work with a dummy load* plugged into the sled?
3) If so, the systems ARE interacting. More tests needed...
* A dummy load could be created by hooking up a 48-ohm, 3-watt resistor (or three 144-ohm, 1-watt resistors in parallel) to a spare blind mate connector. Maybe empeg could provide such a device to an owner with this problem hoping to exonerate their players.
