Righto …… who can explain this system in detail.
CNH batteries ….. one always ****s the bed before the other & I’ve been explained this annoyance a few ways …… but really not convinced of either.

I understand the starter circuit is 24v by the whole machine runs on 12v.

Alternator charges one battery up first, then charges the other. That’s what I’ve been told.

However, I’m lead to believe that there is one battery that basically does all the work & therefore that’s the one that ****s the bed.

So is there a battery equalisation charging system on these machines? YM21 8250.

Soooo about $200 a year to run your batteries depending what you replace them with………..

things must be really tuff in the contract harvesting world………..😉🤔



I wouldn’t know, I did a smart thing and disconnected them batteries indefinitely years ago 😀



your shout on Friday 👍

I found this video helpful.
This is on a tractor but I think its the same as the CNH combines. Yes they have a battery equalizer. Ours had not completely died, like in this video, to blow the fuse but it was barely charging one battery.
Yes, I’m aware of this setup on the “Stieger/T9” …… but not exactly sure if CNH harvesters have that same system.

Both my batteries were 🤬‘ed …… so just buy new ones & keep on going.
