I have a battery load tester that is giving me trouble. A battery load tester is connected to a battery and the voltage can be found. Upon pressing a button on the load tester the circuit is completed between the positive and negative terminal on the battery and the cranking amps of the battery can be found.

The problem I am having is that the wire in the load tester which connects to a metal heat sink keeps overheating and coming separated.

What type of material should I use to permanently connect the wire to the heat sink? I am not exactly sure of how hot its getting, but I imagine it is quite high.

Any suggestions at all are welcome and appreciated!

Thanks!

The best material for connecting the wire to the heat sink would be a high-temperature metal alloy. The metal alloy should be strong enough to withstand the heat generated from the load tester. You can also use a higher temperature rated solder or a special heat-resistant adhesive. Be sure to check the temperature rating of the material before using it.
