Arcing
 

I upgraded my battery cables on my 2017 club car precedent 48 volt cart. I started at the negative and went the whole way around taking each cable off one at a time and replacing it with the new one. I get to the putting the positive cable on last and I get a nice arc. Kinda freaks me out. I’ve replaced batteries in electric manlifts and never had that before. Any clues? Thanks

If there's a Voltage Reducer, they arc when you connect them.

Gotcha yeah I don’t really known of it does or not. I literally just bought the cart 4 days ago. Kinda new to the electric golfcart

Scared the crap out of me the first time it happened with my Yamaha. There is a big capacitor in the voltage reducer that causes a big spark when you connect it to power after it's been disconnected for any amount of time.

Thanks all who commented. I’m gonna go out and hook it up tomorrow.

Yup a little racin but she’s alive again.✊✊

When swapping batteries in a 17 Precedent the Run / Tow switch has to be in Tow or you will get a strong arc.

Re: Arcing
 

You should ALWAYS have the run/tow switch in TOW before working on your cart PERIOD!

You can do this posted by Sergio a while back...It works...

You can use a 40w or 60w incandescent light bulb (old school inefficient ones), just touch the base of the bulb on the battery post and the wire on the light bulb threads.

After about 5-10 seconds the converter capacitors should be charged so you can move the wire to the battery post without a spark.

The bulb acts like a resistor...

Re: Arcing
 

Or just expect and put up with the spark.

I know it is just me being too careful and the chances are low for an explosion, but I don't like sparks around hydrogen gas...Been there..Whatever works for you...

Re: Arcing
 

Thanks for the tip. Next time I do something with the batteries I’ll do that. And yes the cart was in tow mode when I was replacing the cables. Thanks all

No H2 on my cart - Lithium cells. :-) Having a Pre-charge resistor isn't a bad idea - especially if you are making that connection often. I just clinch and connect. But I always unplug my voltage converter power lead at the fuse before connecting my battery. That way the spark is at the fuse and I know for sure that it's just the converter doing it's charging thing.
