proper install of voltage reducer

[yamahaguy97]

hey,

Today I looked at a client's car that the lights were not working. The only lights on the car were headlights. He had a reducer set up in the cart(36v system) and the wires from it were as follows: red is input positive, blue is input neg, black is output neg, yellow is output pos, and orange is for the key switch. Every wire was installed correctly until I saw that he combined BOTH output negative with input negative on the main battery negative! I checked the fuse right away and it was intact. I understand that the input negative and output negative are just grounds, but because there are separate wires for each one on the voltage reducer, I assumed that was not a good idea to do.

So basically I separated the two wires and wired them to their respective wire from the reducer. Turns out after checking all wires, the toggle switch that turns on/off the lights, the lights themselves, and battery pack voltage the lights still don't work. Should I assume at this point the reducer died out?
Do you guys think it is still worth checking the reducer wires to see if I am getting 12v out of it, or is what I described evidence enough??

thanks for any input

Never mind

All negative connection on electric carts go to pack negative. NO frame grounds.

If you has an isolated voltage reducer, you need a negative block for all 12 volt negative connections, then the output negative would connect to the negative block.

Sorry I didn't mean ground wire, but yes the negative output is corrected now and tied into the headlights negative now. But do you agree that the reducer is toast?

I was going to suggest checking the in-line fuse then I re-read the first post.

On second thought, there could be another fuse ( left behind after the reducer was installed)

Yeah you were right to say never mind... Lol kidding. But seriously that is a good point but I did check for that possibility. Do you feel the reducer died out on me?

And yes, I would check the 12v. wires AT the reducer before I'd give it last rites.

Good to go the reducer is a Chinese made cheapie so no big shocker if it's toast

Yep, with all the Chinese stuff, we're going the run out of land-fills.
