Silver Member Username: TejcurrentPost Number: 482 Registered: Apr-07 | I'm sorry, I don't understand the question? |

Silver Member Username: Jesse59672OKLAHOMA Post Number: 623 Registered: Feb-07 | ah idk i just don't know how to wire the thing. i understand + - to battery but why does it say parallel and sht |

Wires 1 and 2 are the units supply voltage, wires 3 and 4 are for the measured voltage! Wire-1 (Cars + voltage 6-24V) Wire-2 (Cars - ground) Wire-3 (Voltage you want displayed - negative) Wire-4 (Voltage you want displayed + positive) The voltage you want displayed can be either a bank of batteries in which wire 3 and 4 need to be wired parallel to the batterie(s) source or if you want it can measure the cars main batter in which just run it back to the starter battery, simple...Polo. PS- You don't want it I can always use it...  |

Silver Member Username: Jesse59672OKLAHOMA Post Number: 628 Registered: Feb-07 | well can i wire 1 and 4 to the battery pos, and 2 and 3 to the battery neg? |
|
Silver Member Username: Jesse59672OKLAHOMA Post Number: 629 Registered: Feb-07 | ah sh!t it would always be on huh |

Gold Member Username: Van_manBoston South, MA Post Number: 2854 Registered: Mar-06 | Use a relay thats wired to a keyed source, so when the car is turned on, the relay gets power, thus powering the unit. Make sure to get a large amperage relay... Uhmmm, You would need a relay that would handle the amps load... Not good. You would almost need to step up to a solinoid to get the job done. I would just use a switch, or leave it on. Im sure it wont drain that much power. Another option may be to wire it indepentantly of the amp. just wire wire 1 and 4 to the battery pos, and 2 and 3 to the battery neg and use a small switch on it like the diagram. That will moniter the battery, but not the amps voltage. Or wire 1 & 4 to the amps +, and 2 & 3 to the amps neg. Then it will only come on when the amps rem is active. |

Gold Member Username: Safe_crackerChicago, IL US Post Number: 3438 Registered: Jan-06 | I would put the source voltage pickup leads, 3 and 4 right where the amplifier connects, this will give a more realistic voltage reading. I also would use the ignition power source to power the unit so it automatically shuts off. Polo.. |

Gold Member Username: Van_manBoston South, MA Post Number: 2855 Registered: Mar-06 | Yes Polo. Thats what I was thinking, but couldnt put it to thought. Over thinking the problem. Try this..  |

Silver Member Username: Jesse59672OKLAHOMA Post Number: 630 Registered: Feb-07 | the whole point of this is to moniter my girlfriends voltage so she doesn't clip her subs. her car didn't come with a voltmeter on the dash |

|
Silver Member Username: Jesse59672OKLAHOMA Post Number: 631 Registered: Feb-07 | we already said that, hom0. then it would always be on |

Gold Member Username: CarguyPost Number: 6478 Registered: Nov-04 | Jesse, let's not get personal with insults. I'm sure Killa was just trying to help. Anyhow, did you even check the manual for that display project/kit? In most cases, they use very little current, in the 20ma range. For that amount, you can leave it on 24/7. It'll never draw enough current to affect anything. If you never turned on your car, it'll take years before the battery gets fully drained. So it's not necessary to install a switch/relay. |

Silver Member Username: Jesse59672OKLAHOMA Post Number: 635 Registered: Feb-07 | yeah but when im bangin her in the car i dont want to see what the batterys voltage is at,.. |

Gold Member Username: JohnfiacA-ToWn, 9515 thumpin... What u bumpin? Post Number: 3547 Registered: Mar-06 | Jesse first off your the hom0 if u dont realize what i just said... it would turn off with the car numb nutts... remote wire..... turns on with ignition... so if the car is off... its off! Remote wire just has a fuse that would help protect it and the ignition would act as the cutoff switch ilistrated in the picture... |
