Re: Hot A2 wire after motor upgrade
Quote:
As a test, I ran to the store and grabbed some (temporary) 4 AWG starter cables and replaced the A2 wire. Drove a short distance, and A2 was no longer getting hot, but now A1 was. Replaced A1 and after a short drive everything seems good now. I'll take it for a longer test later in the weekend and report back. If all is well I'll have the local shop make up a few more cables for me and get everything buttoned back up. Thanks for all of the help so far! |

Re: Hot A2 wire after motor upgrade
Be sure to run the new main negative cable through the OBC you will have to put lug on after routing cable through the hole.

We took the cart out for several longer drives over the weekend, and A1/A2 temps are good. Now F1/F2 wires are getting warm, so it looks like I'll be upgrading those as well. |

Re: Hot A2 wire after motor upgrade
There is no need to replace the F1/F2 wires with anything larger than the OE size of 10 gauge (?) they do not carry much amperage at all... If you suspect they are corroded replace and make sure that the connections are clean & bright and are not loose....

And correct me if I'm wrong (like no one wouldn't) but on the stock 250 amp controller the connection for F1/F2 is a 1/4" Tab Quick Connection which you will not likely find sized to accept 6 gauge wiring... |

Re: Hot A2 wire after motor upgrade
I agree 10ga is all you will need for F1 and F2.
6ft of 10ga wire has 0.006Ω resistance so at 50amps You will be loosing 0.3v on the wires, it is not a factor. The motor would also have to be stalled to demand 50amps of field current. |

As to a "step above the ordinary" why does my 500 amp controller not call for replacement of these wires? |
