David, Most of what I see is relays or circut breakers. I have new 40 amp relays for $15.00 ea and new Littlefuse circut breakers for $4.50 ea. One of the mod's is to replace the wires going to the circut breakers with a ring terminal instead of the quick disconnect. Try to find a brand call Thomas And Betts. I was in the electronics industry for 25 years and they are the best. Bad connectors will loosen up over a period of time, then some else has the problems. Be sure you have a good crimp tool to replace the terminals or you may create another overheating problem. Bad crimps can create electrical overheating and burn up wires and other things. I crimp with a full rachet tool and then solder. It may be an overkill, but I don't have problems in the middle of the road. John vin 11004, 06935,06568 Dherv10@xxxx
