Electrical problem need help

Post by alexcoqui »

It started when the horn went on one night and I had to disconnect the relay. And then I noticed that it was consuming the battery. if the car was not used for about two days it would need to get jumped. I took it to mi mechanic but he could not find the problem. Where should I start looking? Ive heard that under the drivers seat there is usual problem spot, is this correct?

Which car?

You can start by checking for any fuses that are warm after it's been sitting for a while. And using a multimeter to see if any fuse terminals have ground.

You need to do a parasitic draw test.
