Battery keeps going flat

Dallas · 24th November 2016, 12:32

Since I bought the Trophy blue ZT back in the summer, it has always suffered a flat battery. I first thought the battery must be past its sell by date, and a new battery would indeed be needed. Once the battery was charged it would again go flat after 5 days, this was during the summer months.

The problem seems more likely that something is draining the battery, I have changed the battery 3 times with a good replacement. I have 3 good spare batteries in the shed, and each one is going flat once connected to the Trophy blue ZT.

I dont have the CD/DVD Satnav system, but I do have the Harmon Kardon setup, could it be the amp/sub thats in the boot causing the drain, or some relay somewhere?

The plenum chamber is bone dry, the car is a 2.5 V6 petrol manual if that helps.

Cheers guys.
