Re: St. Blazey's Works and Depot

Probably a bit late to the party but... Traction tyres would not be of use on a non driven bogie. Back to your pictures of the lighting boards. The yellow things marked LED x are the white and red lights which would match up to a plastic prism for the actual lights. The three connections on the back...

Re: Converting hornby hst to dcc

I would think your power route is ... Motor bogie left wheels via motor housing to left brush, hence to front light. Other side of light and front pickup right wheels back to right brush. If you pull off the wires from both brushes you will find the left brush is still live to the motor bogie left w...

Re: Converting hornby hst to dcc

It may not be clear to a begineer what motor isolation actually is... Using a multi-meter check for continuity between each motor brush (usually at the brush connection) and the wheels on both sides of the loco, after you have disconnected every bit of wire. There should be no continuity. If there i...

Re: Converting hornby hst to dcc

It sounds like the pickup from the front bogie goes to the motor housing which is likely live to the left hand brush. If so the brush needs isolating from the housing normally by using a nylon screw in lieu of the metal screw or there may be a lug on the housing that the brush retainer strip bears o...

Re: First dcc converted loco start stop

I always improve the pickups on these old models where the front bogie provides one rail pickup and the motor bogie provides the opposing rail pickup. Look for the service sheet for a slightly more modern version of the ringfield motored loco and use the improved pickups from there. Usually the fron...

Re: Hornby Intercity Class 43 HST 125

If the motor is truly dead (although they can usually be fettled) then consider replacing it with a DVD motor.
In true Blue Peter fashion, here is one I did earlier.

Re: Need help with a plan-OO gauge

Depends upon how high you want to lift the rear track(s) but there is little front to back length to get up there without a severe gradient.

Re: Blown TTS Decoder - what did I do wrong?

I was just about to say there will be a beep across the orange and grey with a motor in circuit for the reasons provided above.

Re: Advice Regarding an Automatic Reversing Component

Reed switches need magnets on the applicable passing vehicle. Latching reed switches are becoming harder to find and getting expensive.
IR may suffer unreliability in certain lighting conditions.

Re: Blown TTS Decoder - what did I do wrong?

Do a con test twixt each socket hole (grey and orange) to each motor brush. Grey to brush 1 and 2, ditto orange. You should only get con between the direct connections and not between the crossed connections. May or may not give us a clue. Any way that either of those wires is shorting to chassis. Y...

...soldered in an 8-pin socket...


I would be looking there first. Poor socket, solder bridge, pin touching metal, wrong connection, etc, especially with a ringfield.

Re: power connector clips

You can tighten any fishplate with a flat screwdriver blade. Use the thumb test to find slack ones, they make your thumb hot when you press on them.

Best to learn to solder though.

Re: Technical Timewasting and Equipment Abuse still lives

The aerospace firm I worked at before retirement had a really huge flat bed plotter that secured the plotting medium by vacuum. It was on the ‘works tour’ route because it was as stated very entertaining to watch as it drew up full size parts for aeroplanes on metal or film.
