Learning Curve Getting Expensive
I installed a light kit and keep blowing the front light bulbs. I initially blew all the bulbs (front lights, blinkers and rear lights) when ataching the main leads to the batteries. I thought I was doing it right by attaching the black wire to the positive on one battery, then connecting the red wire to the pos on the adjacent battery. When I went to attach the red...it sparked and blew everything, including the Relay (which I got another at Autozone, except it is for 30A, not 40A..does that make a difference).
I have since replaced the front headlights twice (after rechecking all the wires). The replacement bulbs are 12.8V 55W. Does the .8V make a difference enought to blow them? I have to be doing someting wrong here. Any ideas? Thanks...? |

Re: Learning Curve Getting Expensive
If you get a voltmeter you can test the power you are considering to use as your light source BEFORE you connect
I'm thinking you are connecting to 36v ....... |

And also, if this is on an electric cart (what im seeing in your sig) then it sounds like you are hooking these lights up @ 36 volts which is a big no no and is definitely the reason why you are blowing bulbs left and right. Your going to need to buy a voltage reducer to reduce the 36 volts down to 12 volts. 12 volt bulbs are not going to work with 36 volts of power. |

Re: Learning Curve Getting Expensive
Yes, you are right. I had a big brain fart and am lucky I didn't get hurt.
I was connecting the 12V light system to a 36V system. For some reason I had in my head that it was OK since I was splitting (2) 6V batteries to get 12V by attaching one lead to the corresponding posts on each battery. At least that's how I read the directions, too. So, I need to buy a 12V car battery for my light system and possibly to power a radio. When I looked at them there are different cranking amps. Would the cheapest 12V auto battery suffice as long as I put it on a charge at the end of the day? I intend to get a battery meter for the 36V bank and the additional 12V battery meter to monitor the two different batteries. The same type meter will work right? Thanks.... |

Re: Learning Curve Getting Expensive
Brew you are making this hard for you, get a reducer and you can run your lights and radio from it.

Re: Learning Curve Getting Expensive
I thought they were very expensive. I'll have to look into it. Thanks...

Re: Learning Curve Getting Expensive
Yeah...way cheaper and easier than messing with stand alone 12v battery. I'm going to order a reducer today. Too bad I already ordered (2) volt meters.

Re: Learning Curve Getting Expensive
Check out this wiring diagram for a voltage reducer. I thought you weren't supposed to ground to the frame of an electric cart. Can you ground the reducer back to the batteries? Also, I have a 36V cart, but the reducer says it reduces both 36V & 48V.
Thanks.... |

Re: Learning Curve Getting Expensive
This might be confuesing to some. But the drawing is telling you to ground to a fuse box & then bolt it to the body. The body is not the frame. And yes you should never ground back to the frame.
