Hello All,

Has anyone experienced issues with the ERR Cruise Commander board shorting out after a short period of time. I installed a brand new board in a Weaver RS-3 yesterday.  Everything was fine initially, I was able to assign an address to it, blow the horn and bell and run the locomotive for about a foot before it developed a short.  I checked all wiring, changed out the radio board thinking it may be a bad one but nothing.  I isolated the problem to a short in the main board.  $125 up in smoke in less than a minute, wow. I have installed half a dozen of these over the years and this is the first one I have had problems with.  Anyone else out there experience similar?

Thanks!

Hi John, thanks for the assistance.  Definitely not the mounting screw, it does not protrude past the aluminum mount.  Maybe the motor, will have to double check that.  So the circuit breaker on the transformer tripped when this happened and I do not see anything on the board that appears to be fried or smells that way.  Are these boards pretty resilient to this kind on thing or do you think it is up in smoke?

The Cruise Commander is connected to the track via the 4 pin black molex connector located between the FETs. Pull that connector off the board and see if the transformer still trips. If so its not the Cruise Commander.

Update- the motherboard is definitely the issue, it shorts out as soon as power is applied from the track. Are these repairable and if so who can do it?  Seems a shame that a brand new board lasted less than five minutes.  I had another one in stock, installed it in the diesel and she runs like a champ.  Sound is a bit low even with the pot cranked to the max.  Guess I am used to those MTH units that shake the house when they are running. 

Thanks all,

Mike
