Re: Grey Jaguar No Power Out

Yes, these measurements were still taken with no load on the speed controller outputs. I'll apply loads tomorrow to see what that looks like.

Usually I ran with the probe ground to the negative power supply input because I was hopping around testing both the Victor and Jag speed controllers as well as the PWM inputs to both at various times.
But I also tested with the probe ground to one of the output terminals and saw no difference.

The multimeters were applied just across the speed controller outputs.

P.S.
The other caveat is that I could by chance be working with a damaged tan jag. I'll test with others to see if it's a broad issue.
Update: Nope, I tested three tan/gray jaguars and they all exhibited the same odd response. They were never-been-used 2010 KOP Jags.
