PS1 Help

You could try replacing the BCR with a regular rechargeable battery that looks like a 9 volt battery by MTH, please charge battery overnight, 14 to 18 hours.

Another way to go, but you lose direction control, is to gut the electronics and install a 6 amp bridge rectifier for the motors. I think the MTH motors are D.C. can motors and need a form of a rectifier to work properly. Or you can use the Bachmann/Williams universal replacement reverse circuit board and spend that much extra for reverse.

To upgrade to PS-2 will cost you too much! You could buy a brand new identical engine for almost the same price as the upgrade kit for PS-2 and installation.

Move this thread over to the Controls Forum, MTH DCS section.  There are some very knowledgeable PS1 forumites 'lurking' there.  I just bought a PS1 engine that, while working according to its original factory specs, did not have the degree of conventional control that my other PS1 engines had...it was literally a 'first edition PS1'. 

I received some very good advice on that forum.  You might, also.

I know, I know...the forum sez PS2/PS3.  Well, that's what DCS works with, of course, but the people with the electronics/sound know-how seem to pay more attention 'over there'.  (No offense intended to anyone monitoring this forum, please!)

FWIW, always...

This could be several things:  Replace BCR with a New 9V battery (any battery style will work for testing, but only use a rechargable for long term use) and see if it works.  If still hums check the volume knob and rotate a few time and see if sounds are restored.  Could be a bad speaker so test to see if it reads 8 ohms and is connected.

If still hums could be a multiude of things and it is best to send to a Tech.  Bad top board, bad Voltage regulator, bad capacitors, software issue, etc...  Could be something simple or complex.   G
