12v light to 6v battery

[straightline]

Need some help putting a light on a BBB. Light is a 12v and I connected to the batteries that are powering the winch, headlights etc.. Soon as I put the positive wire on the terminal the bulbs went to blowing. Light has a total of 40 bulbs and it blew 36 instantly. Yes I had the correct wire with each terminal.

First off what's a BBB?

Bad boy buggie maybe?

Bad boy buggy would be 36 volt system or higher shouldn't it?

Yes it is a Bad Boy. There are 8 6v batteries so maybe it is a 48V. Coot I googled and found that but there is no room for another battery.

Everyone should own a multi-meter.

You don't need another battery. You just need to run your light off of two of the 6v batteries that are already hooked up in series.

That is what I did. Same batteries as winch, headlights, radio etc.... Touched the positive and boom, diodes went to popping.

Post up what type of light you have. LED is my assumption since it has diodes. Reverse polarity is a strong possibility since it blew Diodes.

link did not work

Fixed.... I've ordered another one and I'm going to try it again with a little more research this time. Local cart shop wants $200 to install and that might be cheaper than blowing 2-3 up.

So you hooked the white up to positive and black to negative? I would verify with a meter the voltage at the two points of connection. LED light bars are expensive for sure. I take it that 4 LEDs are illuminating? Sounds like Chinese made junk.

Overcurrent blew those diodes. You'd have probably been okay to reverse them.

LEDs have current limiting resistors in-line with the diode. The resistors are designed for a particular voltage. Hooking LEDs designed for 12VDC to 48VDC will produce 4 times the current than the LEDs were designed for.

Stop by Northern Tool and get a cheap DVM for your BBB.


(Digital Volt Meter).

Turns out the two batteries I thought were first in the series were the last. So.......50V in a 12V light is a no no. Thanks for the help.
