airtronics rd8000 problems

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

[1985 kenworth]

When i turn the radio on it showing 10.4 volts

[TRUCKMAKER]

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 !

yes it has the mfu unit in it .the receiver does not appear to have any lights on it anywhere .i just turned on the radio and using another battery i plugged into the mfu unit and when i turned on the mfu the front wheels flickered for a split second like the servo was having a spas attack,that was it nothing else .the mfu light is on the radio says 10.4 volts but nothing,will any bind plug work ..i have a gut feeling it has to do with this receiver .i had a problem with the radio and receiver in my Blue Mule tractor ..it worked fine for about a year then one day it went screwey..the front wheels were shaking the truck would surge forward for no reason so to be safe i changed out the electronics from the futaba to the spektrum..i had no problems since .before i go buying and changing out all the electronics i really would like to have exhausted any and all probable causes first
