After a camping trip I had this happen with my permanent mount PI when plugging in at home on a 110 volt 20 amp circuit and when I turned off the PI the coach worked fine so I killed the breaker and turned the PI on and restarted the process, it chattered again with horribly low voltage readings. After further investigation I discovered that we had left the AH electric heating element and many other electrical devices turned on so the PI was working properly
. After turning off the load mine was fine. Since then I have wired 240 50 amp at my house so no more issues.
