Installed the BRP dual battery kit. Works get. When the isolator connects the batteries is it normal to get real hot?

Everything appears to be functioning properly. I have a voltmeter for each battery. When the main battery is charging at 14.4 volts the isolator kicks in and the auxiliary battery charge jumps to 14+ volts also. When I run the main battery down the isolator disconnects the batteries. It's a pretty slick set up. I noticed that the isolator was hot after riding for a while and shutting the Rhino off. The isolator keeps the batteries connected when the Rhino is turned off until the main battery reaches about 12 volts.
