TR250, 5 and TR6CP Ammeter. We also offer these on an exchange basis reconditioned, or we can recondition your gauge. A cheaper alternative 133117B is available too. see below
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 151272EX 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.
The older ammeters 147962 fitted to TR250 and TR5 were 30 amp rated whilst the face was printed C - D. The later gauge 151272 looks identical but were rated at 50 amps. Our ammeters are all capable of handling 60 amps, regardless of printed scale. The ammeters also have a small overload margin, and will survive higher currents for short durations.
The clamps are available second hand under part numbers 136643/2SH 136643/1SH
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 151272SPEX
