MTH Proto1 – The “3 Clanks of Death” If you hear this sound at start-up you need to have your engine serviced. MTH locos with Protosound 1 are very susceptible to having their main board “scrambled” or “bricked” due to low battery voltage while a high track voltage is applied. In order to avoid this, never turn on a ProtoSound 1 locomotive and immediately apply full voltage. Bring the power up just enough that the engine sounds begin (no more than 10 volts in the first 3 seconds). After 3 seconds you may operate as desired. If the battery does not have a sufficient charge this can cause a voltage spike that can easily scramble or destroy (“brick”) your main circuit board.
What is a BCR (Battery Component Replacement)?It is a battery replacement device for MTH ProtoSound 1 and 2 locomotives. By installing a BCR and applying 10 volts or more for 1 minute (after the 3 second delay for ProtoSound 1) your locomotive will operate as if it has a battery installed without having to worry about replacing batteries or batteries leaking and damaging your engine. We sell both the “BCR” 9 volt (ProtoSound 1 and early ProtoSound 2 Locomotives) and the newer “BCR 2″ 2.4 volt batteries for newer PS2 engines.
Cleanliness is next to Godliness! Lack of continuity due to dirty wheels, collector rollers and track rails can cause a wide variety of issues, malfunctions and random errors. This is especially true for the more modern engines as they require a reliable clean source of power from transformers and control stations. Cleaning your track and engines regularly can save a lot of headaches and troubleshooting not to mention your hard earned money sending your collectibles back and forth to us. Cleaning just one or the other wont do you much good either as one will contaminate the other! Denatured alcohol or an electronics parts cleaner and Q-Tips work great for engines. A paper towel or terry towel soaked with cleaner works great on the track. Rubbing alcohol will leave a very thin residue on surfaces because it has lubricants blended in with it. We do not recommend using rubbing alcohol. Don’t forget to lubricate your collector rollers. Oxidation and carbon build up within the roller due to electrical arcing and can greatly affect the connection your engine has with the center rail.
