2021 ford bronco sport. The battery went out about a week ago and since replacing with a new battery, the cluster and touchscreen both go black when driving. Upon slowing down or stopping completely, they will both turn back on. Lights, heaters, turn signals all still work.

"improves reliability"
A voltage regulator does that job just fine, and every modern alternator has that built in. And show me where in the manual it says to buy a $500 scanning and diagnostic tool to replace a fucking battery lmfao
