The battery was replaced at the same time as was the alternator: 5 months ago

Measurement of battery cables: from battery cable (+) terminal to alternator
(+) terminal: 1.5 ohms. From battery cable (-) terminal to chassis: 1.5
ohms.

Charging numbers with new alternator & 5 months old battery:
With partially (50%?) depleted battery, when the car was started and engine
revved, the new alternator output 34 amps, headlights off. With lights on
high, output was 44 amps. Charge voltage was 14.04 volts. These numbers are
within those specified in the Toyota factory manual (charge current: ³30A or
more²; charge voltage: ³13.9-15.1².

Thanks.


Your measurements cannot be good, or the thing does not charge
the battery. If there were only 10 A, you'd lose 30 V in the cables.

For starting, you will need hunders of amperes, but the battery
voltage cannot put even 10 A to the grounding cable.
