Also check the battery terminal to cable connections are clean and tight.
My first approach is voltage at 3k RPM. Voltage after 1 hour from shut off. Voltage after 24 hours. Don't be afraid to load test the battery. |
Good advice.
My Bosch battery is 2.5 years old. Twice in one month... ~5-6 days between starts... battery was dead. Took it to AZ... load tested it: Good battery.
I had repaired some wires connected to the + cable... and tightened everything up... after the first failure. The second time, after recharging the battery... took it back to AZ: Good, again. Bought the $3 post cleaner. Cleaned everything up.
2 weeks later my voltage LED is reading ~14V.
All back to normal.
