A little more-Opening the boiler room door cooled the machine room until I could stand the sweltering heat, but then that changes the ambient temperat...

Hmm, good ideas there. Was that the Wurtec S3 analyzer? I'm not fond of it, because it has high impedance inputs, that can't tell the difference betwe...

Scott, I'm amazed it's happened to you at all! I had never seen it, or even heard about it. I thought it might have been a one-off problem. When I was...

I hope everybody found this intriguing! I like to solve and write about stuff like that. And I've got a couple more weird ones, if anybody is interest...

Lot of ideas here...You might compare your motor field voltage, and generator field voltage, and armature voltage with a good running car, to see if a...

It's a bit to chime in, but, I saw an Elevonic 401, (w/the processor on the car top), go into the pit when it was fully loaded. The construction super...
