Can you explain it to us ?

Fan came on by its self. Ran for 6 hours then turned off. AH is the batteyr amp hours.

The tool used was a Midtronics DDR http://www.midtronics.com/shop/produ...-data-recorder

Nice tool but its 5k price tag hurts!!

Tool was installed in clients car he left and took the car home. He drove by once a week and we downloaded the data card. We could move the aux lead to different circuits till we narrowed down the circuit with the draw. Then from the circuit we narrowed it down to fuses until we caught the draw. Mind you the trace you saw DID NOT lead to the car not starting it still started barley.

the client had had this issue for 1 year and no one not even the dealer was able to solve it.
