Peter Moore was kind enough to send me a power adapter with the inline diode this week. I installed it and now the Empeg Mk2 will turn off and display the battery icon occasionally even when rolling down one power window. It used to be that one window was always safe whereas mult windows could interrupt the Empeg.

The Empeg also still does not go into soft power-off mode when the ignition is cut for a short time.

Should I try installing capacitors for the Empeg's power from the battery as suggested in this thread?

I have a 1999 Jeep Cherokee without any other power problems.

Thanks in advance,
