Hey,

My battery has been draining recently. I have had to replace the original because it had drained too much which broke it.

Got a new one in and still keeps draining. It's rapidly too because overnight the battery will be dead the morning after.

I regonised a slight humming noise when sitting in the car. So decided to investigate. The humming noise dissappears after the battery is disconnected. So I decided to pull all the fuses and relays one at a time. When I pulled out a certain relay it stopped, and the battery didnt drain. The relay was also very hot so it has always been used.

I just need to know what the T09 Relay is for, and if I need to replace it.

Here's a couple of links that might point you in the right direction

Hi, use the search function putting in T09 RELAY, it came back as fuel pump relay, this should only hum for about 3 seconds before turning the key for final startup & not at any other time.

Thank you very much, your both real saviours. Gonna go to a scrappy tomoz to pick a relay up.

Thanks again!
