Why does my Cummins starter not turn on?
That kind of voltage drop would indicate: Weak battery OR bad cable connection OR bad starter. Start by having the batteries load tested, remove, clean and properly tighten all large connections between battery and starter. If the problem continues, suspect the starter.
Can a blown fuse cause a starter to not start?
Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
What’s the voltage drop on a Cummins starter?
I drove over to Rocky Mountain Cummins and they took the RV in and spent two hrs doing a diagnostic and just like two years ago in Sioux city Iowa at a Cummins dealer they could find nothing wrong. The measured voltage drop on the starter cables were as follows 0.77 VDC on the positive cable and 0.94 on the negative cable.
Can a bad alternator cause a bad starter?
If the alternator is bad, the battery may not be capable of starting the engine. Starter – Some solenoids are mounted to the starter, but some are located directly inside the starter housing. When this is the case, it may be necessary to replace the entire starter when the solenoid goes bad. Sometimes the starter itself is the problem.

What should I do if my starter is not working?
The starter pinion gear engages this wheel to make your car engine crank. Remove the starter motor and set your transmission gear to neutral. Rotate the crankshaft manually using a ratchet. There is a pulley at the front or bottom of your engine block. The pulley should move as you watch how the pion gears are reacting.
What are the signs of a bad starter relay?
Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter. Alternator – The alternator is designed to power all of your car’s electrical systems when the vehicle is running. It also recharges the battery.
