MX5 2002 Battery going flat.
 
Hi all,
My MX5 battery is going flat if not used after about 3-4 days. It is a new battery which tests OK, replaced because the old one did the same. The battery tests OK. I have fitted a battery disconnect switch. When disconnected the battery holds its charge, so a vehicle problem I guess. I haven't measured the quiescent current from the battery yet, but I would doubt that the radio, alarm etc should flatten the battery in this time scale. is anyone aware of issues that might lead to this on the MX5?
Thank you ... John

Current draw test is the only way to go.

OK Thanks. I will do that and then pull a few fuses to try to locate the leak. Thank you
John
