Certainlynot Canadian Tire.

If you measure voltage between two ground points you should also get zero IF there is no current flowing between those two points. If there is current then the voltage you measure will be the current times the resistance.

But thanks Father Y for telling everyone I was a nurdgeek in your own very special kind way! You sure are a diplomat!

Sorry zoomer it was too drastic a voltage drop to be a load issue without (as Yuli put it the car would be unable to start) or even run the car... the amp would have turned on and then gone into protect as the amp and the battery get real hot real fast.

The symptoms did not indicate a shorted output or fault in the amp
