Some time ago I bought a 2nd hand Bachmann Speed Controller ( input 16v and Output 12v) and at long last I started to try it out.

When I turn it on to maximum my voltage tested says that it is giving out 20v !

Surely this isn't normal .... is it a scrap bin job??

If is a scrapper ... any suggestions as the the best controller that I can get for my "DC only" track?

It's not uncommon for the output to read much higher when there is no load. It will drop when under load.     

Try measuring the voltage from the power supply when it's not connected to the controller?  16V AC results in DC peaks of 22V

Just use common sense and run your locos at realistic speeds     If you check the voltage when you're actually running a loco it'll be more reasonable.

Those Bachmann controllers are well known for giving out high DC voltages. I use one on a shunting layout and it is fine if used carefully.

As to a 'better' controller then there are a few brands to choose from. Gaugemaster are probably the most well known. Others on here have recommended Morley Vortracks.

I have both Gaugemaster and Morley controllers but still use my Bachmann controller from a set to run locos in on my test oval
