Actually I think I figured it out with the help of Bogart Engineering. The default shunt is the 500 amp and is what the meter is set up for. I installed a 100 amp shunt. So I must get into the programming and change the value of P11 to the 100 amp shunt. (Or change out to the 500 amp) Otherwise the amp readings are off by 10 times. So my -90 amp reading is actually -9 amps. Sounds much better. I will know if this is the problem for sure tomorrow morning when I get back out to the camper
