Battery Isolator very hot.

See if you can use the laser thermometer to narrow down the source of the heat. Check all the connection points and crimps. Try pulling the crimped connector off each end of each cable. There should be no play at all.

Harbor Freight has a hydraulic crimp tool for about $60.

Pasdad1 is dead on. The echo charger should be connected fine. It is basically bypassing the isolator if it is working correctly. Having batteries that went to 2 volts means you need to seriously change them out. Especially if you have done it several times. They have been damaged terribly.

Take the echo charger off, replace the batteries, Let your onboard charger bring them up and then run your engine. Only then should you put the echo charger back on.
