is there anyone who can provide some help with wiring a JM-1?
If so, I'll forward a link to this thread to the customer who is having issues.
He's having problems working out the wiring from our wiring diagram, which does look a bit confusing, to my inexperienced eyes.
So, if you've wired a JM-1 or JMA-1 I'm sure you could help walk him through it.
