I don't agree 100% with the brush shunt rating. The reason being is that when I had a Fantom dyno I ran a motor just hooking the leads to the shunts. Then I did it just hooking to the brush hood without the shunt connected. With the connection to the shunts it made a big difference in the readings (higher).
I know it is not a scientific test however, we need to give the shunts more amp carrying capabilities than they deserve. Now maybe they can only handle 5-10 amps for so long.
There is great need for a sarcasm font.
You never know when it will strike, but there comes a moment at work when you know that you just aren't going to do anything productive for the rest of the day.
