looking for 12 volts in reverse
I ran across these small led back up lights and I got the idea of putting them on the cart powered by the reverse side of the f/r switch. The back up buzzer's orange wire which is the coming off the 2nd limit switch only seems to have 4.7 volts when put to a common ground . The other red wire coming off the buzzer goes to the solenoid but that is not switched by the f/r.
Is there a way to do this or its a good idea that won't work ? |

Re: looking for 12 volts in reverse
There's got to be a way to do it...
Could you somehow mount a switch near the back side of the FR switch that gets either pushed or released when you move it to Reverse? Do you have the lever or rocker? |

Re: looking for 12 volts in reverse
Hmmm, this might be the perfect application for my X'mas tree lights solution (from when I did my headlights/& LED tail lights in series). Wire 4 little 12v "backup lights" in series and mount them to a decent looking bracket. Then extract the power directly from the backup buzzer circuit (which I think is 48v) and VOILA a cute little string of backup lights without wiring separate switches or making power conversions etc.

Re: looking for 12 volts in reverse
Wait - are you saying the backup buzzer isn't 48v? (The back up buzzer's orange wire which is the coming off the 2nd limit switch only seems to have 4.7 volts) I could have sworn it was....

Re: looking for 12 volts in reverse
Funny - the buzzers are labeled 9-48vdc, so in my head, I had made the assumption that a 48v label wouldn't be there unless that's the voltage it would be seeing (or with a lever, maybe 24v - the reverse voltage). 4.7 volts just seems weird. Does the red wire (which is not switched) lead somewhere from the solenoid to something other than pack negative?

Re: looking for 12 volts in reverse
I think this might work ... don't know your 12 v set up
but i know you can get a 12v back-up alarm/buzzer |

Re: looking for 12 volts in reverse
CTD : I was only getting 4.7 volts off the orange wire going to a dead ground . the red wire on the buzzer is live also. is the orange a ground ?

Re: looking for 12 volts in reverse
If you follow that diagram, Red should be 48+ and Orange is 48- when the circuit is in reverse.. You could get a 48 volt relay to be the light switch and then get power from where ever for the lights.
