Alt not charging

[brndck]

correct. my stack cluster does have a voltmeter built in, and you can monitor battery voltage. when you first fire up the car it will just sit static around 11.5-12v, and slowly you can watch it trickle down (takes a while, its not immediate), but if you free rev the engine (just once, above 3-4k, then let it sit back at idle), you can see the alternator kick on and start producing 13-14v.

I'm curious to see what anyone else with a STACK or AIM digital dash has experienced when deleting the factory cluster. Or even people who just ditch the cluster and use like Defi or greddy gauges.
