We have a fleet of 23 FC4000 lifts. All of these lifts have trouble with the battery connector, lift connector and battery connectors both, overheating. This manifests in connectors getting stuck together and in severe cases melting. Our batteries have 4/O cable on them, but the cable on the truck is 2/O. I had an idea that this may be the root cause and explored the option of installing 4/O cable on the truck from the battery connection to the buss bar, but the lugs for a 4/O cable won't fit on the buss bar. I'm just wondering if anyone else has experienced this on these or other models?
