OK All my lights work when I push the test switch and all are off normally but I have a constant alarm.I have checked all grounds,checked the bus bar fuses behind panel and no changes. Only thing I can think of is I have a bad panel. Any Suggestions???
 
I had the same problem. Only time it would shut off is when batteries got very low. I found a brand new one from MM, I think it was about $175.00. Took 5 minutes to swap out and all is normal now. Hope this helps.
 
I would try and straighten the antennas...

Gary,

That will probably start another thread on antenna positioning! Of course ECs came from the factory with that design which means that your antenna position might not be as aerodynamic as an ECs ........resulting in even greater fossil fuel consumption!!

In regards to the board, it's usually the test switch or the relay on the board that goes bad. I think that there are a couple of services that will repair them. If you can find a new one for $150-200, I would buy it.
