Hello guys I have a small problem with my newly accuired 300td. The car has been sitting for a good deal of time. I replaced the water pump and hoses. I put a new battery in it and it has been running good. The battery goes dead after a couple days. I have to jump it. I checked with the engine running and at idle it is 13 volts. Revved up a little over 14 volts. I unhooked the battery and placed my fluke meter to check amps. It is showing a 5.9a draw. I did it at night and there is a big spark. What could cause this amount of draw? Thanks guys for all the help. Robert
