Rear Coupler Issue

Add a small non-polarized capacitor across the coupler leads. This will adsorb the voltage spikes that are opening the coupler.

Hi Chuck are you saying add a small non-polarized capacitor to one side of the wiring of the coupler? I don't have any capacitors I'd have to order some. Can you tell me what to order so I get the right one? We used to have a local Radio Shack but they all shut down. I'm hoping it's something that I can even get at Lowe's or Home Depot. Thanks

Gary, you want to use a 50 volt, 1 microfarad, non-polarized capacitor.  The non-polarized part is very important since a standard polarized capacitor could explode when it gets the AC pulse during uncoupling.

Like Chuck says, wire the capacitor across the two coupler leads (like you are shorting out the leads).  I've added lots of these to my TMCC locomotives.

If you have a Hobbytown in your area, might give them a call, Many Hobbytown stores are a Radio Shack express store within.

The best place to add the cap is right at the board, I usually try to solder them under the board to the coupler connector.  That also avoids having to splice into the coupler wiring.

Bob and Gunrunnerjohn I put in the 50 volt, 1 microfarad, non-polarized capacitor on the HobbyTown website and it's telling me no products. Do you have a better description on the capacitor so I can find them. Thanks Guys

I'll send you one for the cost of shipping. 5.00. Email if interested.

Hi Chuck I'm interested. How do you want me to send the money to you? I've sent money thru PayPal before. Let me know and I'll send you my address . Thanks for doing this for me. Gary
