Sorry for the delay. To clarify, I had the 1200 and now I have the 1250.
On the 1200 I had 3 weeks away from the RS and the parasitic drain from the USB charger drained the battery to the "no crank" state. I then fitted an on-off switch to the circuit and all was fixed.
On the 1250 I forgot my Sena in the helmet was plugged in to charge for 5 days, and that also gave the no-crank state.
The jumper batteries only gave me a "1 crank" result.
All was fixed by using my charger, but it took just under a day to fully charge.
My error may have been to attempt to crank too soon after connecting the jumpers.

I would like to apologize to anyone I have NOT offended. Please be patient. I will get to you shortly.

Thanks, Wessie. A good idea. I do have a Fluke 88 automotive meter, that I just scratch the surface of.
When I get free cycles, I'll dig in. I love YouTube teaching videos.
