I'll see if I can work up some other of your requested constants.

Sentry Dyno
work proceeds. The digikey 200 A sensor came in. I decided the best install would be to put it in the same little circuit board the original came in. I desoldered the large shunts first then the 3 small leads from the sensor. I cleaned the small holes out with an X-acto knife point. The new device slid right in when I bent the shunts. According to the wrapping this is a static electricity sensitive device. I imagine the little capacitor on the circuit board may help it be more robust after installation. Anyway I discharged myself on the barrel of the soldering iron before it got hot and proceeded. Here are some pics. Wish me luck. I have a new GTB in as well to test on the 3.5 motor.
