Battery Testing

Dear Tadge,

I am testing the battery on my 2003 corvette with an AVR machine using half of the battery's cold cranking amperage (CCA). I connect the tester's load leads to their respective battery terminals and connect the tester's inductive amp pick up around one of the battery cables.When I dial in the load with the load control to the specified value and hold it for 15 seconds , the AVR machine starts to smoke. Is this normal? I am trying to see if the voltage stays above 9.6 but I am afraid to burn the tester. Best Regards

I don't think so either, but as mentioned above, smoke is usually not good.

What AVR machine are you using (model number)? I'm guessing that if you can dial-in the load is because it can take it, but could it be that you are exceeding the time it can be under load or its duty cycle? Have you checked its documentation?

I have my doubts that Tadge is going to help with this one, so I am going to move this over to the C5 Tech section where hopefully someone can help you.

Thanks I am using the Snap On AVR. The documentation says to hold the load for 15 seconds and you want to see the voltage NOT to drop below 9.6 volts

well now that you let the smoke out of the tester, you may want to go to the zone and use theirs. If they let the smoke out of theirs it wont cost you
