hi you need to measure the voltage drop to the warning lamp as if the feed to the warning lamp is lower then the battery voltage you have enough to light the bulb.
however its also worth checking to make sure the warning lamp wire hasnt been connected into for things such as caravan tow socket.
hope this helps martin
