    The train takes off,like a bat out of hell,while the throttle lever is on 0.You have to use the on/off switch,to stop the train.The miltimeter shows a steady flow of volts.On 0,it reads 14 volts,turn it up to the max,she reads 24 volts.Hit the boost botton,she reads 25.5 volts.The train,I`m using is a 1957 thru 1961 Lionel 246 Scout.This pack should run this train,according to MRC.

It is not supposed to drop to 0 volts. It is a pulse width modulated supply designed to limit speed by decreasing the "on time" of the voltage, not the level of voltage.

    There may be something about the older motor that is not compatible with the PWM output, but I would have also thought it should be fine. Do you have the option of returning the supply or trying it on a newer layout?

    A pwm controller will not appear to go to 0 volts on a meter. You'll need an oscilloscope to see the changing pulse width.

    Dave - I just had the same thing happen to my Throttlepack. I'm using a very new MTH Subway model engine. It was working fine, and then all of a sudden I turned on the power switch and the train took off with the Throttle at zero. Have you been able to solve the problem? - Joe

2009 451 Passion. Why a frequent dead battery?

That is definitely wrong, not normal. Voltage should stay at 14 volts or near that until the battery is close to fully charged, then will slide down to about 13.5 volts, and stay there while engine is running. Also, a fully charged battery should show about 12.6 volts at a minimum, especially a new battery.
I don't know what is going on with your system. Take it back to Merc- were they aware of how it is acting, voltage-wise? Doesn't sound like it. One small possibility: is your alternator belt not tight enough?

Your battery is dead and alternator may not be charging. Try a jump start. If it starts, check voltage with engine running. If voltage is less than 13, remove the alternator and have it tested.

I have a 2002 ford ranger that got a lot of water in the gas. I have drained the tank and added heat as well as replaced the filter. When I try to start it the battery gauge goes down to 0 and all I hear...

The alternator isn't charging , check B+ voltage hook-ups on the alternator . The heavy gage wire on the back of the alternator should have B+ voltage , vehicle not running . The fuel pump has nothing to do with it > terminal 3 at the connector should also have B+ voltage , So should terminal 1 . Charge the battery an get the vehicle running , put a volt meter on the battery post's , if there is about 13 to 14 volts running it is not charging !

Car will start when it is being charged, after charger is removed car still runs, when car is shut off it will not restart

could be battery or alternator. Check voltage at battery with engine running. Should be at least 14 volts. If yes, alternator is working.
After charging, battery voltage should be over 12 volts, with engine off. When starting, battery voltage should not drop a lot. If battery voltage does not drop while trying to start, you may have a bad connection--loose terminals.

These new graphics cards pull a lot of power from the power supply. I know you didn't start off having this issue but given the symptoms you are experiencing I'd take a closer look at the power supply and perhaps replace it with a 650 watt or better.

Amp not getting sufficent voltage

Does the car start with the voltage dropping like that? Sounds like a bad battery. A battery can show 12.6 volts and as soon as you put a load to the battery the voltage will drop. I would change the battery and see if that helps. Also check your alternator. Get a DMM set to DC volts connect it to the battery and see how far the voltage drops when the cars running. You should see something like 14 volts or so. If it drops below 11 volts you may need to upgrade the "big 3" wires...hope this helps

Dimming lights and voltage drop

Its not unusual to have a sudden drop of volts. especially if you have something running like your a/c or heater that requires a lot of power to run. it will also do it when your fan kicks in. anything that requires power is going to kick down your voltage. i would not worry about it unless the battery starts to die overnight.
