My boss replaced the old battery with a new one. but he think he wired wrong, because when he did the 12 volt monitor for the reverse camera started to smoke;and the battery post get hot
Re: My boss replaced the old battery with a new one. but...
Hi,
When you are lucky there's a protection diode blown.
Thats a protection for people who are trying to reverse the + and -.'
If not, you have a serious problem.

It's a guess, but..... Because it only works with the door open, I am thinking there are broken wires or chaffing where the wires go from the door to the door jamb. 12 volt power, grounds and speaker wires don't mix and could have easily blown the circuitry in the old one.
yes you can find generic info on this. most all the systems, no matter name brand, have the same basic installation.
you will need a 12 volt power source for the monitor. the camera power will come from the reverse lights power source(tap into the power at the reverse light), then you will need to run an rca style cable from the camera mounted position to the monitor itself.
so every time you put vehicle in reverse the camera comes on.
or you can wire the camera and the monitor through a switch and it will come on anytime the switch is turned on. but if you do this, the switch need to be wired to a ignition controlled power source.
Bob make sure that the wiring is connected correctly to scooter controller in other words if the cables from the batteries have a connector that plug into the harness coming from the controller make sure that connectors (if color coded) match up and that they are seated correctly. Look on the underside of your rear shroud for a wiring diagram and make sure that the new batteries are wired in that way Hope this helps
If your unit is not maintaining it's memory, it may be associated with the lack of a constant 12 volt power source. Test the units yellow wire, it should rest at 12 volts with the key in all positions; off, acc, on/run, start. This yellow wire should be connected to the vehicle's battery wire. Also, test the red wire. This wire should be connected to a switched 12 volt power source. It should read 12 volts with the key in accessory and on/run only. If you used a vehicle specific wiring harness to complete the installation, the wires may be switched in the harness. It's not a common issue but, I have seen it happen.
The gauge could be wrong,it could be defective,have the alternator checked,at the battery,it should read from 13.65 volts to 14.25 volts with the head lights on,and the ac blower on high,with the engine running.If the alternator is new,check for 12 volts at the back of the alternator with engine off,if there is not 12 volts on the large wire,on the alternator,then the circuit is broken somewhere.Just install a new wire,of equal or larger size.Leave the original wire on the alternator,and just add a new wire,larger would be better if possible,and run it from the alternator,to the positive side of the battery,it will fix the problem.
When its hooked up, you should be able to put 12 volts on the little stud on the solenoid and it should start. One large stud will have 12 volts on it, so just jump it right there. Did you get the wires in the right place. The solenoid should have 1 large wire going down to the starter. Be sure the battery cables are clean and tight ( both ends) Check battery voltage when cranking, should go to 10-11 volts. Check voltage between negative terminal on battery and engine, should be ZERO when cranking. The solenoid has 2 large studs, make sure the battery positive wire and all the other wires are hooked to this stud, the other large stud should just have the wire going to the starter.
Check your solenoid to starter output. If you are not getting 12 volts out, replace the solenoid. If you are getting a full 12 volts, check the input to the starter, if you don't get 12 volts there, check your cable for loose or corroded connections, if you do get 12 volts, replace the starter
12/29. I actually figured this one out myself after reading posts concerning parking brake over rides. It turns out that the Boss BV9055 will not powerup if the pink parking brake wire from the units wiring harness is not grounded. Once I grounded that pink parking brake wire the unit did power up.
Hi John.
No idea why your post is under monitor problems ???
I figured you need an adapter mod for a monitor !! SO don't kill my
ratings since this is not my area of expertise, but I can try to give
you some input anyway, not so much a solution !!.
I would NOT recommend altering a 12 volt adapter for charging a battery
especially if it is a standard ac adapter.. You may get it to give you
13.8, but your amps may be wrong.
Battery charger depends on type of battery also. Don't know if you are using NIMH or Nicad or acid based ?
The differnt style batteries use different type chargers. Wrong charger will burn up a battery or blow it up !!
If the battery is a 13.8 then normaly the charger would be putting out
2+- volts more than the battery rating. If you battery is 12 then a
13.8-14 would do the trick. (12 volt car batteries for instance take a
14+ volt source to charge them)
I would recommend looking here

They have all those goodies and may give you an idea. for what I think you are doing.
