I have a 2016 BB All American that all of the speakers quit working. I changed the radio, INT/EXT switch and don't know where to go next. Any ideas? ED
Yep, we have the issue all the time. The drivers crank their radios up so loud when they're empty that they'll blow a speaker and then they all quit working. They're like the old Christmas tree lights. Get a little jumper wire and connect the spades on each speaker until they start working. That's the one to replace. That said, we have seen multiples that are harder to diag.
Well... I have been having some other electrical issues on this bus also. Seems like we have been getting water in the electrical system panel. Relays have been corroded on the fuse panel. If I ground out the wires at the plug in for the speakers at the radio I can get each side to all work as they should. I thing I have a corroded ground somewhere that is causing the problem but now to find out where, ED
Just an update on this problem, I tried to find any wiring problems and couldn't find anything so I ordered a new INT/EXT switch and that solved the problem. I know this sounds stupid but I had tried the old switch earlier in another bus of the same vintage and it worked in the other bus.I again tried it on the other bus after i got the new switch and it worked on that bus. This doesn't make sense but it happened. Live and learn I guess. Ed
