How to Detect a Low Battery
Even rechargeable batteries sometimes lose their charge (especially if they are stored for long periods of time) and eventually need replacing. A bit of routine maintenance can keep your engine running properly. The following symptoms are indicative of an undercharged Proto-Sound battery:
If you are experiencing any or all of the above problems, test the battery as follows:
Try a quick charge. Place the engine in neutral with the throttle set at 15v and the smoke unit turned off for one hour. Alternately, you can 1) plug the M.T.H. Battery Charger (Item No. 50-1005) into the battery charging port (if your Proto-Sound 2.0 engine is equipped with one) and charge for one hour or 2) remove the battery and charge it in a a battery charger that recharges at the rate marked on the battery (11 mA) for 1 1/2 hours. After the quick charge, test the engine. If it performs better, continue to charge the battery as described above for a total of 14-16 hours to ensure a full charge.
If the quick charge does not seem to improve engine performance, test the engine with a different battery installed.
Install a regular 9V battery (follow the operating instructions for that engine) and test the locomotive to determine if the battery is the cause of the problem; if the engine runs properly with the 9V battery installed, the NiCad battery has lost its charge. Charge the original battery for 14 - 16 hours as described above or order a replacement battery. You can continue to run your engine with the 9V battery in the short-term while you await delivery of your new battery. However, because the engine will try to recharge the non-rechargeable 9V battery the whole time it runs, we do not recommend this as a long-term solution.
If the battery does not work after a full 14-16-hour charge, you must replace the battery. To do this, follow the engine's operating instructions.
You can purchase a new NiCad battery, part number BG-4000001 from MTH for $10 or buy a 8.4V 150 mAh Nickel Metal Hydride battery suitable for use in M.T.H. engines from Radio Shack (stock number 23-529). It can be found online at www.radioshack.com.
As many of you know, Proto-Sound and Proto-Sound 2.0 engines are equipped with a rechargeable battery to enhance sound system operation. It is thanks to this battery that your realistic sound effects keep playing as you interrupt track power, and the battery allows for the realistic shut-down sounds at the end of an operating session. While the battery recharges automatically as you run your trains, even rechargeable batteries do not last forever.
A survey of our service calls suggests that many of you are not familiar with some easily solved problems like the signs of an undercharged battery or of an engine that has been locked into a direction.
Fully 1/3 of all engines returned to M.T.H. for service could easily be serviced at home by charging or replacing the battery or by checking to see whether your engine is locked into a direction. We know you would much rather keep your engines at home where you can enjoy them, and to help you do that, we are publishing a list of symptoms and tests to see if your engine ails from nothing more than a low battery. Please see the list below (also available at www.mth-railking.com) for tips to help you maintain your battery's and engine's health. You engine's operating instructions contain all you need to know to unlock an engine that has been locked into a direction.
Until this winter, M.T.H. has been able to provide routine battery maintenance and even basic operational assistance like an unlocking service for free. However, as part of our effort to streamline our service and reduce turnaround times, we now charge customers for recharging or replacing a battery and for simply unlocking engines as described in the operating instruction. We encourage you to perform these simple forms of maintenance for yourselves, allowing us to spend our time on engines in more serious need of our professional service. The charges for battery maintenance and unlocking engines are as follows:
The customer who returns an engine for a low battery can opt to have the engine returned as-is (for the $25 diagnosis fee), or to buy a battery for $10 and have it shipped with the engine for him or her to install (for a total of $35), or can have us replace the battery (for a total of $50, see above).
In addition to the tip sheet below, your engines' Operating Instructions and a troubleshooting section of the M.T.H. website contain information that will help you find the information you need to charge and replace your batteries as well as perform other easy maintenance and basic operational checks at home.
Of course, when you have problems you cannot resolve yourself, we want you to feel free to contact any M.T.H. Authorized Service Center or M.T.H. Service. You can find an Authorized Service Center near you online at www.mth-railking.com or you can contact M.T.H. Service by filling out the Service Contact form in the Service Section of www.mth-railking.com; sending US mail to the address listed below; telephoning 410-381-2580 or faxing 410-423-0009.
