Bowser Sound Chassis
Posted by markie97 on Saturday, July 21, 2012 7:28 AM

Hello;

I recently purchased an unpowered Bowser sound chassis for a Stewart F3. I installed a motor and drive from an old but unused Stewart Kato F3. Everything seemed to work fine except:

1 - On initial system power up I would usually have to "jiggle" the engine on the track to get engine to react. After that it would typically run fine

2 - Yesterday it ran fine while I adjusted the speed table, today it does not run in reverse.

I suspect there may be something about the fact that it was originally sold as an unpowered unit. Maybe there is an additional resistor in the mix???

Any help will be appreciated.

Thanks,

Mark

 Doesn't look like anythign diffrent in my powered one. The dummy units seem to be identical witht he exception of no motor - I have a dummy one I put a DSD-LC decoder and big speaker in (didn;t need more motor - the A unit pulls plenty by itself). And I have an powered B sound chassis, it looks identical to the powered B that came with the set other than the Tsunami stuck in there and a speaker.

 What do you mean by jiggle it to get it to go? If the motor frozen up but the sounds work,unless you give it a little helkp, is everythign dead, or is the motor freely turnign and the sounds work and it won;t go until you push it? It's possible installign the drive broke a wire, leading to poor pickup. Did you swap trucks? If so, are both pickup wires soldered to both trucks to get the full 8 wheel pickup? If it's binding the motor, maybe the drive train components are too tight, either pushing out or pullign in on the trucks, Of if the motor just spinds, maybe there's a gear missing or misplaced so it doesn't engage unless you give it a push.

By jiggle I mean I get the wheels off the track a hair maybe a few times. Prior to that no sound and no motion. After that it works fine at even speed step 1 and through insulfrog turnouts etc.

Thanks,

 That sounds liek somethign that could happen with a chassis that uses the truck bolsters to pick up current, but those models have wires on both sides fo the trucks. At least, all mine do - but mine are all the newer Stewart drive with the Buehler motor, not the older Kato ones.
