Bessaccar pump and light problem.

[phillspider]

I’ve recently purchased a Bessaccar E540 and when any of the taps are used and the pump starts running the courtesy lights by the door come on, when the taps are turned off the lights remain on for about 20 seconds before they go off, the lights are working perfectly on their own.

Have you checked any wiring to see if it’s damaged or fitted badly?

Would also be worth checking the condition of your batteries, could just be poor battery charge/voltage.
