checking amperage on 706 gas generator

Id stick an ammeter in series and see what it reads!! If you dont have an ammeter but a voltmeter see if the battery voltage rises from around 12.6 when shes setting versus running at fast RPM where Id expect it to rise to at least 13 and up to around 14 or a bit over depending on the genny and battery and RPM

Learned this a long, long time ago from a very wise old Delco-Remy mechanic down in Omaha.

Forget the ampreage.

If the voltage is holding steady where it should, the ampreage will take care of itself.....you know, Ohm's law and all that.

The other replies gave you the practical answer. The technical answer is install an ammeter in the circuit going to the battery and then use a carbon pile load tester to keep the battery voltage low enough so that the voltage regulator will command full output.

The maximum amperage output should match what the regulator is set for. The voltage regulator controls both voltage and maximum amperage. As load is applied to the battery, voltage should remain constant until the maximum amperage is achieved. After that, the amperage should stay constant but the voltage will drop. Anything less than maximum amperage will be controlled but the electrical load and the battery's capacity to accept a charge.
