I installed a NOCO Gen5x1 onboard battery charger last weekend on my 2013 2500. It worked nicely but last night, with truck parked and plugged in, I happened to see that the dashboard lights were on/cycling. Has anyone seen that happen before? Could it be because of the way I hooked the Pos and Neg cable from the charger to the battery? Should the Neg be connected to battery or to the chassis? I m also wondering if the Battery IBS has anything to do with this??
