They are polarized, meaning that current is made to flow through them in a preferred direction. If you run current through them the wrong direction, they tend to run hotter than normal. If you look closely at the breaker case, you should see some small print designating the terminals as either BAT (for the battery side) and ACC (for the accessory side). To identify which wires come from the battery, check with a volt meter or test light to see which wires are hot while still disconnected from the breaker. > Of all the dozen solutions out there, is there one that is do-able without > investing another $300? Try replacing the hot relays if they are OEM. Even Radio Shack sells a 30A rated relay that will fit okay. Walt Tampa, FL
