RAV 4.2 charging voltage

[bonjo]

would like to check the voltage at the Battery terminals and the engine RPM.

Does anybody know this?

I am not after the volts at the alternator (which involves disconnecting the charging system)

thanks a lot

Not sure what this poster is after. A volt meter or multitester will supply this info. do you have either of these? The reason I ask is because both voltages can be checked from the Battery terminals in situ so there would be no need to disconnect the alternator to check the output, also if your motor does not have a rev counter one could be fitted by an auto sparky

the charging system supplies a certain voltage at certain engine speed to charge the Battery (typically 13~14V @ 2000~3000rpm)

What I would like to know is what these numbers are for RAV4.2 (petrol) at the Battery terminals

thx

A alternator puts out a 13/14 volts from tick over RPM and is unaffected by increased revs which can be read at the Battery when the engine is running
