Late TR4 and TR4A flat glass Ammeter, consider non-original part 133117B or exchange part 133117EX. The clamps are 136643/2SH 136643/1SH

This instrument has Lucar electrical connections and flat glass. The case is plastic ( with its own illumination) rather than metal for practical reasons. When Lucas produced these instruments originally with a steel case the gauges had a Bakalite back separating the positive and negative connections. These cases were very special and were only cost effective due to the volume being made. If a standard steel case is used, electromagnetic interference can cause adjacent gauges, especially the fuel gauge to read incorrectly. The plastic case used to house our ammeters removes these problems completely. Rest assured that the gauge looks original when installed in the dashboard.

Our manufacturer can produce a special steel case if required but this is very expensive and generally not as satisfactory as the plastic case. If ultimate originality is required please order 133117EX which is an original gauge usually sold on an exchange basis. A deposit will be charged which will be refunded if an old reconditionable gauge can be returned to us. 
 
This ammeter reads 30 amp + and -. Our ammeters are all capable of handling 60 amps, regardless of printed scale, in this case the instrument is calibrated to 30 amp. The ammeters also have a small overload margin, and will survive higher currents for short durations. 
  
Gauges can be altered to special order to suit customer requirements such as reading 60 Amp to 60 Amp to ensure the gauge is not damaged when used in conjunction with a high power alternator. We can also arrange for the gauge to accept 60 Amp to 60 Amp whilst maintaining the the original face to preserve originality. Order part number 133117SPEX. See below
 
A full set of 4  instruments is available new as are a range of the two larger instruments.
