Installing Converter

[Venteuri]

Hi guys. I didn't want to pollute the other ongoing thread so I started this one.

I got a converter/reducer that has the following cables:

I will connect to battery red and black. And red/white to trigger on switch.
I will connect to fuse block +12V yellow.

The question is: -12V negative to buss bar..... this means NO wire from buss bar to negative pack. Correct? The converter 48V thin black will do this function and close the loop?

I'm sure someone can give a much better answer. I just wonder what if anything you would get if you hooked it up without the 12v negative to the pack, and then take a DVM and probe the negative bus bar, and the 36v positive. I'm thinking the two grounds are bridged inside the reducer.

The instructions seem pretty clear; no connection from -12v to -36v.

I think is the same concept as yours. But with an extra trigger cable..

Yours have 4 cables. Two inputs and 2 outputs.

Same on this.
The inputs from battery pack
The outputs to fuse block - accessories and to negative buss bar

,thanks.

Just needed confirmation.
I was confused after reading all in the other thread.

Yes, and it will certainly work without putting the -12 on the -36. I'm just thinking that the grounds are bridged inside the unit. Otherwise I don't see how it could put a ground out. So I'm willing to bet that if you hook it up as directed, and then probed the negative bus bar to positive 36v it would give you positive 36 reading.

Meaning the grounds are bridged.

You should also have a 12v reading, by probing the +12v on fuse block and the -36 ground at battery pack.

Agree .

I'm installing a fuse block from reducer to accesories.

Reading the info it suggests installing a 125Amp fuse... should I put one?
It's coming from my reducer. I assume I don't need it.

What you guys say?

It's 125a Max since you have a 30a converter, if you put a fuse on it, doesn't need to be more than 30a.

Thanks ARKS
Should I even put a fuse? There's a fuse between the pack and the converter
