Title: Low voltage
Post by: jjwdadof4 on July 15, 2018, 05:49:32 PM

If I'm getting a low voltage message does that mean I need to add more leads to get better power around the track? I'm only running two locks

Thanks
Josh

If you don't get the warning when the loco is at the spot where you have the leads now and you do get the warning when the loco is furthest away from the leads then yes, adding more feeders will solve the problem. You could also solder the rail joiners or bump up the power supply by a volt or so if you have that option.

You'll also get the low-voltage warning if you have spotty power connection.  If your loco wheels or track are dirty then that message will pop up.  Cleaning both will typically solve the problem.

Ok thank you both for the reply back I will do both add a couple more leads and clean the track and wheels

Also if you are using the Full Bridge Rectifier with a Keep Alive you will see the occasional under voltage warning. As stated, more feeders will generally help.

I noticed when using LM-2S/2 and the bridge rectifier there was lots of low voltage alerts because of the voltage drop. The LM3/3S is much more suited to using a keep alive as there's no voltage drop to the module. Occasionally I still see it when the train has lots of power up front, but it never affects performance and is normally gone within a few seconds.
