Battery Cable Getting Hot
I have an 89 Marathon - resister cart. I have gone up one larger guage on the battery cables and one size on the motor. It has been this way for 2 years with no issues.
Recently, I noticed that the battery cable connected to the forward/reverse switch is getting really hot. Enough to cause the coating on the wire to bubble. It is just this one cable, not the others. I checked all connections and they are tight. Could my switch be bad? What could cause this? Thanks! |

Re: Battery Cable Getting Hot
Heat is always caused by a poor connection! It could be your cable end not making a good connection on the switch, the terminal end on the cable is not making good contact to the wire itself, or the contact in the switch not making good contact on the wiper board. Check each one of these connections! Be careful feeling around for what's hot!!! It will get very hot!

Re: Battery Cable Getting Hot
I would probably replace that cable. If the cable looks at all bad or corroded, I would consider replacing them all. Just my opinion......

Re: Battery Cable Getting Hot
I suspect the F&R is starting to melt down and the heat is showing in the soft cable cover. Remove the center pivot shaft nut and slide the shaft and the switch cam out for inspection . See diagram (note turn diagram upside down & eliminate shifter linkage for Marathon cart).

Re: Battery Cable Getting Hot
Thanks for your input. I took the F/R switch apart and found the nuts that go all the way through that make the connection to the rotating switch were lose and needed cleaning. I replaced two suspect cables, cleaned all the battery terminals, and tighten them. I have not gone on a long trip yet, but I think this should get it. Thanks again.

Caution when you tighten up the nuts it pulls the studs away from the Rotary contacts. I'm sure this makes sense - having seen the inside of the switch. |
