Car batteries

[Mugwump]

..check your battery terminals folks....Jan's Blazer was having trouble starting, normally pops over with a vrooom...even in cold weather....I visually/manually check both cars often....oil, belts, filters, tires and tire pressure, coolant, etc.....but her terminals looked good.....nope....
pulled both off and the 'pos' was corroded in between the terminal and battery plates......sheesh....cleaned em up good, and a shot of WD.....
Vroooom......I miss post batteries.....

just say'n....sometimes the visual isn't good enough....     nope
