Testing for battery drain.

[LarryW]

My engine battery drains nearly dead in about 5 days. Charge it and disconnect from coach and it looses nothing, Hookied up it will go from 13.4v to
11.5v over a 5 day period. What is the best way to test for parasitic drain?

Put a test light between the negative battery terminal and the negative
lead. If you have a drain the test light will illuminate. Start pulling
fuses one by one while watching the light. The one(s) that makes the light
dim or go out are your issue.
