    Caveat - I'm an electrical numpty but can wire a 12v DC model railway and make it work.:)

    However.....as I'm about to rebuild Setforth Junction I'm taking the opportunity to upgrade the control panel and the controllers to get better smooth running. So I'm going to invest in Gaugemaster DS series controller, and a HF2 track cleaning unit, but also want to put a panel meter in to monitor current. Gaugemaster tell me I would fry the ammeter with the HF2:eek:, so I could put a DPDT switch in to operate either the HF2 or the ammeter. Does anyone else use an HF1 or 2 with an ammeter, and if so how have you done it?

    Whilst most trains on the up or down lines run the same way they do occasionally run in both directions - and of course the sidings and branch do too on a more regular basis. On another thread in this section I can see a link to an Australian site where multi directional ammeters are available and there is also China. However I would rather purchase in the UK – any UK members able to point me in the right direction as trawling Google, Amazon and E Bay is proving fruitless unless I want to spend £40 plus.

    Or is there another way I’ve missed?:scratchchin:

    BTW DCC is not an option.

    Hi Dave

    Depending on what you want to measure, you could just measure the mains current consumption of the DS controller. As this would be main current a great deal of care must be taken, or you could use a simple mainsa socket detector

    These cost between £10 & £30 depending on functionality and brand name. (sorry for the above picture didn't realise I clipped a non-uk example).

    If I remember correctly _ it is over 40 years ago, and I struggle to remember whats for lunch, the ammeter has a large shunt resitor, the HS2 will see this as dirty spot and try and fry it out of existance. The HS2 is designed to be permanently connected, and as Gaugemaster make both units and don't reccommend or supply an ammeter, I'd probably follow thier advice.

    If you run your two heaviest locomotives hauling decent length trains, monitor the DS's current consumption, do the same for the loco's running light, then with your lightest loco, this will give you a normal min and max levels, so a quick glance will let you know if everything is within normal parameters.

    For individual loco's I'd use your old controller add a cheap Ammeter / Voltmeter, and use it to power a rolling road on your workbench, so you perform run-ins, maintenance etc away from the layout.

    Hope this helps

    Paul - many thanks. I hadn't though of just having a piece of test track wired up separately - sometimes the obvious isn't apparent when I'm thinking down one particular track. And if I do that, it means I dont need to allow for reverse polarity - by putting a DPDT switch after the meter I can run locos forward and reverse from the 12v output and there is no need for a track cleaner as wheels will be cleaned as part of maintenance, and wiping a short piece of track isn't an issue. A rolling road is on my wish list.
    There are 2 layouts on You Tube - Barrie Davis with Cranworth Model Railway and Al in the loft with Buckland Junction, both of whom are using an HF2 with panel meters so I've dropped them a note to ascertain their experience / wiring set up.
    The reason I'm looking to put them directly onto the layout is there was a problem on the previous build with a section of track I never got round to fixing, so having constant readouts of current and voltage would have perhaps proved useful in ascertaining the problem. I was always dubious about a point that was inside the tunnel - I could get to the motor but not the track. As part of the move that point had to come out, and wont be going back in with the revised fiddle yard layout.
    Still waiting for the new lighting to arrive before doing anything else (including building the control panel with or without meters!).

    Hi Dave for the point, is it electrofrog or insulfrog.

    As a test try bridging the switch rail to the stock rail, and see if that improves, then try the stock rail to the wing rail, it just maybe a poor connection on the wiper contacts between the stock rail and switch rail, especially if the track had been glued, ballasted and or painted.

    For scales/ gauges N, 3mm, OO/HO, EM & P4 I have the DCC concepts rolling road and works fine - well I've only tried OO & P4. For O gauge I have a more substantial device, but in both cases they were well worth the money. And you can runin more than 1 loco at a time, even in DC.

    Its electrofrog. I had to remove it when SJ got dismantled as it was on a board join. Fortunately it wasnt ballasted as it was just inside the tunnel. I will check it out before re-use.
    And I've already started looking for a DCC concepts rolling road :thumbup:
