Re: charger not cutting off
Quote:
There is about 6' of 8Ga wires between the charger port and batteries and with 10A of charging current passing through them, the nominal voltage drop of the copper conductors is 0.038V. You can add a few more Milli-ohms of unavoidable resistance in the connections, but with 10A of current flow you should see less than 0.1V difference and without the charger connected, there shouldn't be a measurable difference (unless you are using a DVM that resolves down to micro-volts) |

Re: charger not cutting off
If you can measure 47V at the main battery terminals while the charger is pumping amps into the battery pack and the charger is shutting off normally when attached to a different cart, the problem is somewhere between the main battery terminals and the charger port.
Personally, I'd cut off about an inch or so of the existing 8Ga cables at the battery end and install new 5/16" ring terminals (solder on type preferred), then reconnect the new ring terminals directly to the battery terminals, leaving out the fuse if one is installed. If you have kids or anyone that might place a metal object in the charge port and short between the +/- radsoks, put the fuse back in the circuit after the charger is working correctly. --------- The trick is to get the same voltage at both the main battery terminals and the charger port. |

Re: charger not cutting off
yeh you know I though about trying that first. don't know if I have enough cable length. yes I am definitely soldering them. I'll let you know how it goes.
thanks for the ring terminal size, I didn't have that size at my work. |

Re: charger not cutting off
Not all carts have them.
There was one on my cart when I got it (lower right in attached picture), but I have since removed it. |

Re: charger not cutting off
put on new ring terminals at battery connection and soldered. fixed it, charger shut off after hour and a half. still thinking about running new wires, but it looks like 10 gauge after going to home depot. cant really tell.
thanks for your help. |

Re: charger not cutting off
The original wires might very well be 10Ga, but if possible and practical, use 8Ga.
