Batboard

Hello guys. i wondering if anyone has experienced this problem. battery on ht goes dead while in mva with power on and it would not transmit. now it seems to me that the radio should still work weather the battrery is dead or not while in the cradle with power on. welcome feedback. manual does not have alot of details.

I don't believe the accy port on any Jedi radio supplies power.

But the contacts on the back of the radio battery should be receiving power from the cradle to power his radio. That seems to be his issue, as I'm reading it.

It will not work if the battery is totally shot or shorted inside. Is your battery known to be good? Does it charge and hold capacity when a regular desktop charger is used? Have you tried using another battery?

i was told that you are supposed to have the radio turned of before putting it in cradle so you can initlaize the mva so i will try that and have the battery tested. thanks i will let you know what i find out

battery is brand new. i have copared voltage reading of the contacts from a known good charger and the mva. and the mva seems to be sending negative voltage which is drawing battery down. so i guess i have a deffective control unit. wow brand new too.

Hard to believe a brand new Motorola vehicle charger is bad out of the box. What has become of my beloved /\/\... Shite happens though . Guess there's no sense in asking if it's been wired to the car correctly?

At least you looked into the easiest parts of troubleshooting the problem first, and it has nothing to do with the radio or battery.

yes it is wired correctly unless they sent me one for positive ground system

Theres an Mss in Munster, 20 minutes from you.

oh that is correct thanks

Where is the selector for the battery adjustment which is located on the side of the unit. It is normally selected with a quarter or a penny and will be used when you have an NTN7144 instead of the NTN7143 battery. I had many a PG fire ambo have a 43 battery with the selector in the 44 position. It would never charge the radio's battery and would work till the battery died. This was only after they figured out how to shove something into the bottom of the radio to "make it work" supposedly.

yes my son made me aware of that .thanks
