Fuse Blocks

[LouisC]

As I stated a few times in previous posts, I'm a dummy when it comes to electronics. I'm thinking of adding a fuse block. (Here's where I have no clue). In previous posts I said I was going to add back-up LED lights off of the reverse buzzer. So I was thinking of adding a 10 space fuse block between my volt-2000 reducer and 12v power to the relay (I was told acts like a switch) then to the rear lights. I have 5 wires on the reducer - yellow to switch, 48v + and 48v -, 12v + and 12v -..... The 12v + would go to the fuse block main post. What do I do with the negative 12v wire ??? Then coming off one of the 10amp fuse spaces a 16awg wire would go to my relay then coming out of my relay another 16awg wire go to the positive of my lights....What do I do with the negative wire from my lights ??? Told - not a good idea to ground to frame so I'm a little lost...HELP

It seems to me that if you shouldn't ground to the frame then all the lights' negative wires must be wired back to the 12v negative wire from the reducer.

Don't take my word for it. Never owned an electric cart.

Right now the LED Headlights and Tail Lights are hooked up to a harness which is somehow hooked up to the 12v + & - of the reducer. This will change as well and come off the fuse block -- I Think ????

Your fuse block will have a negative side where all the negatives from each accessory come together and the positive side where each positive is fused before going off their respective accessory. From the 48V to 12V reducer, the +12V will go to the main +ve terminal on the fuse block and the -12V will go to the main -ve terminal of the fuse block.

This diagram shows what I mean:

You probably don't need a relay on the twelve volt side unless you've got an accessory (such as a big light) that pulls more power than the switch you are using can handle. Given that the reducer can only output 30A and you can easily find a switch that will handle that, you don't need a relay.

The relay he is referring to is a 48v relay in parallel with the reverse buzzer.

The +12v is only going to the relay N.O. contacts to switch the 12v backup lights.

Bought a Blue Sea 5025 - 6 circuit with negative ground bar & cover...I believe it will work just fine...Thanks for the guidance...

The 12v positive wire from the reducer would be the wire you use to feed 12v power to the fuse block. Get a fuse block that uses one stud for the fuse block feed.

Something like this.....

You need a fuse panel and a grounding strip, then all your 12v accessories can be wired to them.
