Voltage reducer

[RamV]

So i hooked up voltage reducer form carts unlimited on my 05 club car. It works very good but each time I disconnect one of the batteries and connect back i get a good spark. Is there any way to get rid of that spark ?

You would need some way to supply power to the reducer while the batteries are not hooked up. Or you could put a power switch on reducer.

Run your positive wire through a fuse then through the key switch or any kind of switch then to your reducer. Then when the key or switch is off no spark.

the yellow wire goes to the key switch , or an on/off switch

If I'm not mistaking, to keep the Sparks away you need a switch on the red wire.

Not sure but you may also need a resistor, and or diode. Sergio where are you.

i hate to say it but your mistaken
the yellow wire energizes the reducer
if it has no power then red wire is dead , no spark
done a few scotty reducers in my time
never used a resistor, and or diode
the diagram is what scotty sends out

The first time a DC-DC converter is powered after is has been disconnected from the batteries, there will be an inrush of current as the input capacitors inside the voltage converter need to charge.

What I do on mine is to use an incandescent light bulb (60w or so) and run it in series with the positive cable for a few seconds.

Just stand the light bulb on the battery post and touch the cable on the threads of the light bulb, a 60w light bulb is about 240Ω and it will charge the capacitors without a spark.

You can then just put the cable on the battery post without a spark.

Those input capacitors will then stay charged, using a very small amount of current, even if the Yellow trigger wire is OFF.

I will not disagree with you. I was just looking at the wiring diagram, I have no hands on experience with that reducer to speak of.

I have yellow to ignition switch, green to accery box, red to batteries And black to ground per sheet scotty sends out. The diagram just showed has green to light switch , i have light switch to acessary box.

i run green to fuse box
