Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

Got my conversion completed today.
I added a picture (second one below that shows exactly what needs to be cut out on the front of the battery bucket to do this.
I show the passenger side because I wanted everyone to see the main wiring harness that you really need to watch out for while cutting the bucket.
I also added a partial marine battery box to my installation. Probably not necessary, but I feel a little better knowing that I have a "bucket extension" holding the first and sixth battery in place.

I trimmed the battery box, then used a heat gun and bent the tabs to attach to the battery bucket with speed nuts and screws.
BTW, the batteries pictured are junk, they will be my cores when I get a new set in a couple of weeks.

Here is the nice clean bucket...unmolested

That's a big chunk out of the front of the bucket. Without the addition of my battery box "pocket, I suppose this opening could be about an inch and a half narrower. This also shows all of the cuts needed for this conversion. There are six cuts on the floor and the seventh cut is the front of the bucket.

Had to cut some of the bottom off of the stock hold down to cover the #1 and #6 batteries.

Okay I've got a 05 precedent and did this conversion and everything works including the charger but my only problem is is I couldn't get but 9 volts out of my light switch reading. The lights do fine until I mash the gas all the way down and then the lights go out. I have a aftermarket LED kit this a plug-and-play setup

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

I cannot recall the fix for this, but I do recall Sergio giving a member a solution with some diodes or something that fixed that just in the last week or two. If no one else responds soon, PM Sergio to look at your post.

thank you I will I'm in a very remote campground right now and services is very bad. dang it

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

Sounds like you are now trying to run lights off one battery 8 volt. You had 4 12 volt batteries and running them off one 12 volt battery was working. If this is true you need a 48-12 volt reducer.

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

I do plan on ordering one. But it being a plug and play. I'm not sure where it's grounded at. I know the positive is coming off last battery from a blue wire with a circuit breaker

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

If by "last battery" You mean the one with the pack negative cable, then You are just using 8v.

The accessories negative comes off Controller B- on a Club Car with a working OBC.

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

it's actually hooked up to the positive side of last battery

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

what two colors do I cut to make headlights work with a rreducer when I get it in . being shipped.

Re: DIY - 4 x 12v to 6 x 8V Conversion (Part 1)
 

Okay I'm going to try and ask this ? again I'm not good with schematics so on a 05 model president's golf carts where does it get its positive and its negative from for the light kit harness look like it's all just plug and play unlike the ezgo I had.. I know that the positive comes from the blue wire that goes to the last battery but I'm not sure where to get the negative from I just got my voltage reducer in so I'm ready to wear it up. The reason I'm tagging on this post is because I did the same conversion. Please help if anyone can. I went to a local deal all they had was the newer precedent carts and it's cotroler is located in back and they pulled off a blk/w striped wire out of the wire lum
