- Modern AC fuel pumps on a locomotive pull much more current than the original equipment relay is designed to carry, especially those equipped with electronic fuel injection.
- Original relay load rating - 10 amps
- Current measured on EFI equipped engine - 24 amps
- The higher current load leads to premature failure of the relay
- The turbo lube pump application is at the upper limit of relay current capacity
- Relay Systems offers a high capacity relay which easily carries the additional load of an EFI engine fuel pump
- Continuous rating of over 30 amps
- Direct replacement of existing relay
