Well, a hair over 1 year after installing a BCR for my 9V PS2 locomotive, the sound started cutting in and out while running. Even let it charge for more than 5 minutes before running. Checked, and it's only putting out 6.5 volts. Anyone else seen this?

Its rare. But as stated, failure of BCRs have happened. Originally designed for the PS2-5 volts with the BCRs replacing the 9 volt batteries which can cause problems especially if they corrode and one is unaware.
I don't have anymore PS2/5s, but when I did, never had a problem with BCRs. Some which were over 5 years old.

I don't run my MTH engines often enough to keep a battery charged. So BCRs have been a blessing to me.

Just remember that batteries can leak and corrode causing damaged to items close by and even destroy boards. One reason there are no batteries in any of my engines and use BCRs. They may fail, but they also won't cause damage. Reason also I check all my controllers each week on Sundays to make sure none have corroded. I have caught the start of some corroding. I use alcohol to clean up.
We do same for all our flashlights especially those we may need in an emergency.

Batteries will leak. I remove them from my controllers when I'm through running the trains..

Yes, there are a few versions out there. I am not a great electrician, so I buy the finished versions from a fellow modeler…

BCR are just capacitors. if J&W are using cheap ones I can see this being a issue. If you have a PS2 2.5 volt engines a super cap of 1 Farad will do the trick. 5 volt PS engines I would use what Ben recommends. Since the 5 volt board s prone to failure, a battery that can keep a charge is the way to go.

How is this for battery leakage?  it wasn’t the white battery that leaked, as far as I could tell. I believe the engine is an early QSI equipped engine…before PS1, conventional operation only, with sound…   I have a number of the batteries suggested by Ben. One of those is going in after the major cleaning project… Tom

Diesel erratic in a lash up – Had an MTH NYC GP-40 20-2371-1, 9v unit with a 2015 overpriced JW BCR that failed on 6-29-24. Lasted 9 years! Notice the cracked case and blown hole. Measures only 4 volts now. Lifetime Warranty so I emailed them yesterday. Diesel runs smooth in forward and reverse but with any other diesel attached in a lash up it operates jerky in either direction. It will start rolling normally then starts to surge fast and slow down the track. I have over 50 PS 2 & 3 engines mostly 3v from the mid 2000’s. I use 3 dollar 5V Digi-key super caps on those if needed and never had a failure. Generally, I try to avoid the poorly designed 9v Power units with some exception like this one. |
