no power to slide out motor

[lippend]

2008 Cedar Creek with no power to slide out motor. Following supply wire to back wall of front storage area, wire is connected to "power strip" with 2 copper strips, over and under. Upper strip has power, lower does not and that is where wire is connected.
If I jump from batteries to positive lead on trombetta and ground, slides work fine from inside switch.
30 amp auto fuse in breaker panel is fine on/off switch for slide is fine.

Any suggestions?

Thanks.
