2014 Sprinter Diesel 3.0L with LTV camper on the back and 13K miles. Dealing with some low voltage error codes popping up and subsequent ABS/EPS/Traction control systems being flagged and disabled. Took a look at overall system voltage, so I put a multimeter on the system and noted 14.1v on idle, which is fine. But when I revved the engine a bit, noted voltage dropping to mid 12v range on my FLUKE. This consistently happened repeatedly when making small revs on the engine. I don't find this normal and wondering if the alternator or regulator are going bad or if some load is kicking in when engine rpm increases above idle. Curious for any thoughts on the matter. Thanks.
