airtronics rd8000 problems

[TRUCKMAKER]

I have the same radio and the OEM transmitter battery is a very small capacity. If I even think about looking at that radio I plug it in and charge it. I think I charge it more than the truck battery. It's just a thought but if you didn't, you might check it.

Thanks Truckmaker i replaced the small capacity radio battery with a larger one
.i think its a 2200 .when i turn on the radio and the mfu i hear the blower in the smoker unit

I have absolutely no functions at all ,not even.lights which are on a battle switch on one of the channels. Could it be that the receiver has gone bad

When i turn the radio on it showing 10.4 volts

Did you try rebinding the transmitter to the receiver? I think it said in the manual that if it sets for a while you might have to rebind it.

Will any bind plug work or does it have to be the original

You have a MFU so I assume the reciever is powered by that. Maybe it's not?
Is there power at the RX ? Any lights on it?

Oh, and never put external power to the reciever when connected to a MFU !
