BIM160 Chassis Battery Charger?

[Lucky Lady]

This is what a BIM 160 looks like, although I am a bit surprised that they were installed as early as 2016.

Hi David,
I am guessing I don't have the BIM 160. Is this what I am looking for, a previous "BIM" model?

The BIM terminals are clearly labeled... amazing how the Thor assembly kids messed that up! To check just use a voltmeter and check continuity between positive battery post and corresponding correct BIM terminal. No beep... no joy!

Asking David as well...is this my "BIM"? May not be a 160? Thanks in advance

On the left side of the left picture is a Trombetta solenoid which connects/disconnects the chassis and house battery banks together. To thhe right is the BIRD - GAS that is the "smarts" to control the solenoid.

The solenoid is a common failure item and can be easily replaced with one of many available on Amazon.

You do not have a BIM. See Ace's reply.

....

Mine charged just fine until I switched to lithium house batteries and the lithium bim.

My theory for it now not charging is the voltage differential(though it used to click every 20minutes or so and now I hear nothing).

....

FWIW, if you have solar contributing to your house bank (don't know if you do or not), do not expect the LiBIM225 to contribute alternator charging to the bank while the sun is shining. The solar raises the house battery voltage above the threshold that the LiBIM is looking for to allow the alternator to connect so it won't.

Thanks for the reply. Is it supposed to act just like the BIM? To charge the house battery when plugged in?
Thank you as always!

Yes, but a BIM has the solenoid and "smarts" integrated into one device.

Alright awesome thanks! I appreciate all the help from you.
