Will the engine run ok if there is no load on the generator or is it unstable at all times?
Of your Cummins diesel generator won't generate electricity or any problems, please follow the guide below to fix it.
1. Wrong connection of generator set. Processing: check and correct by wiring diagram.
2. Generator speed is too low. Processing: measuring speed and keeping it at rated value.
3. The connection between the stator winding and the generator distribution equipment has sludge or oxide, the connection screw is loose, the connection wire is broken, and the stator winding is broken. Handling: use a multimeter or lamp test method to find out where the wire is broken. Check the connection and contact of each connection screw.
4. Excitation circuit broken or bad contact. Processing: use multimeter to identify broken wire and reweld the broken wire to bind insulation.
5. Rectifying tube (including rectifier diode, thyristor) is damaged. Treatment: replace damaged parts.
6. Brush contact with slip ring bad or brush pressure is not enough. Treatment: clean the surface of the slider ring, polish the brush, make it match with the surface of the slider ring, increase the brush pressure.
7. Brush grip rusts, brush can not slide up and down. Treatment: wipe the inner surface with a cloth brush, if damaged, should be replaced.
8. Cummins generator exciter brush position is incorrect, brush damage or spring pressure is not enough. Handling: adjust the brush to the correct position, replace the brush, adjust the spring pressure.
9. The prime mover rotates in the wrong direction. Processing: changes the rotation direction of the prime mover.
10. Cummins generator exciter winding wiring error, polarity reverse. Handling: correct winding connection and recharge magnetic with dry battery and battery according to its polarity.

have you had the vehicle speed control reprogrammed if not that could be your problem

sounds like the cabbruter is losing pressure cheak tubes may be lose or damaged

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

Well the sensors are reporting a failure in the engine/transmission. So either they are right or wrong has to be assessed by the nature of the alarms or sensor faliure, but the problem remains, hence if all primary steps of investigation start by hooking up to a PC specially built to rectify such problems. This facility is available at most of the gas service stations/centers..................sodeep

usaly You use a OBD 2 Scan tool if you do not have one you might want to disconect battery for a minute then reconect the battery how ever keep in mind if you do not fix the switch that cause the *eng light* to come on it will return when you start the car up again,Hope this helps ,John
