Ballast Resistor - BTJ2877 Genuine BMC Part
Ballast resistor is located under the tractor dash. Use only if still on the original 9 volt system.
BMC Mini, Nuffield 4/25, Leyland 154 early models fitted with a generator
Note: Most tractors have now been transferred to the 12V system, and therefore this part is redundant and has been bypassed. If you have the 12V glow plugs then you will not ned this ballast resistor. However, if you have the original 9V glow plugs on your tractor then you may need this part.
