Beware eBay & Amazon chinesium hall effect meters, those bargain deals are more meant for kids science projects than a vehicle installation.

Yah, sure some people have better luck but I know of 5 or 7 that went wonky or blank after 40 or 50 hours - that includes two for me, really bummed when that $60 do-it-all energy monitor went imaginary numbers 2/3rds through building out my second 300AH bank.

Sorry I don't have superior alternate to link, just a reminder we get what we pay for...

... I note “Factory Setup” has;
1) 70amp upfitter fuse
2) Spare slot for a “mega” fuse or in @Sather case and others seemingly a 250amp factory installed fuse in the spare location

My point is Ram must have taken these upfitter loads into consideration. IIRC the 220amp alternator is supplied in “The Ambulance Package”. I would think they (Ram) has designed some sort of control (& spec’d limits) around their alternators & regulation of.🤔 ...
Seemingly? :)

Here are some pix for clarification. First has empty slot, second has the 250 amp Mega fuse. Lot of them out there...

Allegedly... :)

Good Advice @Zoomyn

I have had 1 “experimental avionics” for 16 years with zero issues, but not for 220amps & no cheap off shore 😳
