Attached pump battery wrong way round!

[Bringus]

Rushing this morning, stupidly attached battery terminals to pump wrong way round. One fuse on pump had blown so changed that, but still not working, any suggestions, please?

Controller has blown. If its a Spring controller, Spring can repair it but it will take time.

I would replace it with a new one.

Expensive mistake. Make the connectors, so you cant get it wrong
