Hi Wojo,
Just found your reply. Thanks. I have not done much more with the top since my last post. But I have always suspected the yellow solenoid since the fuse does not blow if I unplug the yellow one. I must admit I don't quite understand the operation of the solenoid in this application, but have wondered if the solenoid could be jamming the pump or have a short of its own. Do you know if removing the solenoid for inspection is wise?

 

You have 2 relays for the pump motor up and down controlled by the security module. When it sends a signal to the relays that are being protected by a 5 amp fuse it sends power to the pump to operate and it is protected by a 40amp fuse. The latch and main control valve is controlled by the security module.

This is a link to wiring diagram for 2003 and fig 5.2 is what you want to look at.

It should not if done properly.

 

Thanks, although the schematic is Fig. 15.2.
