Do you own a volt meter?

Has any testing been performed?

How long must the vehicle sit before the batteries go dead?

Please reply if further discussion is needed.


Ok you have verified you have a parasitic draw which is discharging the batteries. You will need to follow this test which will require the use of the volt meter and removeing fuses to see which circuit is drawing power.

Basically,I put the ammeter inline between the neg cable and the negative post. I should have an exessive draw ( 50 MA). Then i remove one fuse at a time to find the one with the high draw.
It would be very nice if the image could be printed bigger
