Battery load test numbers

[Ray-IN]

I had the Prodigy also and like yours it was asleep when not in use but I often left my truck sit for more than a month between uses during the winter months and never had any problems. With a diesel truck I did have two group 94 batteries in parallel. My son was also running a Prodigy in his Toyota gas truck that he towed with and had no problems.

I'll find out if the controller is the problem, next week. I plan to to park it in the MH garage for the week and test/ record battery voltage every day at the same time.
The truck will not start/turn over when the battery is at 12.2V/ 65% SOC. Interstate (3x) and Sams Club(1X) testing shows the battery is good.
Battery connections have been removed, cleaned, re-tightened. I have not tested battery cables for high resistance.
The 12V wire to the M&G braking system has been in place since 2013 without this problem, but I removed the 5A fuse and it didn't change the DC amp-draw with engine not running.
The RV shop that installed the Prodigy(I'd had it for years-new in box) said it is old technology and has been replaced with a new electronic design.
