Ryan_1995 Posted April 10, 2013 Share Posted April 10, 2013 Hi, I was wondering if anyone could help me. I have purchased two Hornby 4VEP motor bogies to power two kits I have just built. I understood these to be complete units, however when I place them on the track they do not run? So do they need wiring in any way? Thanks in advance for any help, Ryan Link to post Share on other sites More sharing options...
Guest oldlugger Posted April 10, 2013 Share Posted April 10, 2013 Hello Ryan, They are self contained and don't need extra wiring to run. The only wiring would be to connect them to the trailing bogie, if used. Check the four wiper electrical contacts behind the wheels to make sure they are touching the wheel rim rears. The motor is a five pole semi can motor and shouldn't need any maintenance. Do a flying leads test on the wires coming out of the motor housing and see if the motor is running OK.

Madcaravanner Posted April 10, 2013 Share Posted April 10, 2013 Not sure which motor they use Is it an enclosed can style one or the old style Triang one with one arm of the spring that retains the brushes in place that is insulated ??? like this Link to post Share on other sites More sharing options...
Ryan_1995 Posted April 10, 2013 Author Share Posted April 10, 2013 They are brand new but I tested them anyway - all is fine. All the metal contacts are touching the wheels. I have had a closer look and it appears there are no connections from the pickups to the motor, I will try soldering some wires from the metal pickup plates to the flying leads and see if I have any success. Thanks,Ryan Link to post Share on other sites More sharing options...
frobisher Posted April 10, 2013 Share Posted April 10, 2013 They are self contained and don't need extra wiring to run. The only wiring would be to connect them to the trailing bogie, if used.I'd be very surprised if Hornby supplied them that way as they would need rewiring if they were to be used as replacement parts. The pickups and the motor terminals are not directly connected but go via an external circuit board incorporating a DCC socket which is not supplied with the bogies (confirmed by looking a the service sheet here (http://www.Hornby.com/downloads/service-sheets/Hornby-service-sheets-351-400/)). The leads coming out of the motor housing are from the pickups and don't go to the motor terminals and you have to make that connection yourself.

Guest oldlugger Posted April 10, 2013 Share Posted April 10, 2013 It's a much newer style motor than that Gray. It is a small can motor, from Hornby assembly diagrams that I've seen. Link to post Share on other sites More sharing options...

Well mine was self contained and worked without any connection to a trailing bogie Link to post Share on other sites More sharing options...

Such a motor bogie as you received would not work at all well as a straight spare substitution for the a DCC fitted 4VEP. Link to post Share on other sites More sharing options...
Stevelewis Posted April 10, 2013 Share Posted April 10, 2013 I dont think they are self contained! If they are 4-VEP power units then as the 4-VEP is either digtal ready or digital fitted when purchased, the power collected from the 4 wheels HAS to be routed first to the DCC Decoder socket from there it is re-routed BACK the motor's power input connections. To make yours work identify the 2 connections from the track and the 2 connections to the motor then solder a connection between them ( this is assuming you are only going to use them Analogueically (is that a real word!! I mean DC only! Link to post Share on other sites More sharing options...
Ryan_1995 Posted April 10, 2013 Author Share Posted April 10, 2013 Ok so I have soldered some wires from the pick up plates to the flying leads - it works but due to the traction tyres the pick up is quite poor, so I will solder some more wires to the other bogie for a better connection to the track Link to post Share on other sites More sharing options...
