[RE-wrenches] Strings and series of batteries

[Joel Davidson]

Dust and dirt get stuck to Vaseline, grease and other sticky substances. 
Some particulates contain metal that can form a conductive path from the 
battery terminal to the case. Test your "battery bucket" for leaks by 
putting one of your voltmeter lead on the terminal and the other lead on the 
case. Dirty car and truck batteries in damp weather often leak current.
