I have a project car i'm trying to figure out,
It turned on today no problem and i drove it for about 20 minutes and when i got it back home i turned it off, i went to turn it back on and battery was completely dead, multimeter read below 12 volts i think it said 11.94,
Battery is a bosch from may 2015
I put in a new alternator and voltage regulator both are grounded well
Battery connections are good and tight
The only loose connection i found was from the engine block to the body of the car would that cause a non charging issue?
I'm trickle charging the battery now
