CR-V - what is this connected to my negative battery post

Left side of the pic. It's cracked, connects by 2 wires (a blue and a white). Goes to a bundle and out of sight.  Thought I'd check here before making a 30 mile trip to the nearest dealer.

Might try taking it off and see if there are any part numbers or markings.

Ask….and ye shall receive.  There are all sorts of “thingies” that the car boys are putting on.  There is USUALLY a high current fuse on the positive.  I always carry a spare in every vehicle.

NOW….this device is basically….a sophisticated “Battery temp sensor” with a “amp meter” probe….and a “bonus”….Voltage sensor. Critcial to the voltage regulation of your alternator…..it goes bad….you COOK your battery….

You can google it and there is a LOT of info, some wrong…LOL, about it and what all it does….

@Tom Cherry Wow!  I appreciate you so much.  I think you must be a walking parts catalog.  Or the world's top Googler!  In any case, thanks for coming thru again!!
