 Topic: Starter Solenoid
Posted: 09 Mar 2017 at 1:51pm |

Guys all of a sudden my D10 is just buzzing at the starter when I turn the key (some of the time). Is that the starter solenoid going bad?
Thanks,
Jeff

What makes the buzzing noise? The starter itself, or the solenoid? Usually if you at least get a click, the solenoid is working.

Absolutely maybe. You could have a bad keys switch or connection. Check these items first.

is the solenoid attached to the starter or separate? If the solenoid is separate you can use a screw driver to jump the terminals and see if it starts. make sure it's not in gear or you'll have to chase it down if it starts... make sure the motor still turns by hand and didn't seized up.

Do it right and check it out with a VOLT METER ,start at battery and go through the system .

If the solenoid buzzes its a strong hint at a bad battery or a bad battery circuit connection. When the solenoid contacts close the current is suddenly a few hundred amps and a dirty battery post can have enough voltage drop to cause the solenoid to open, then close and open as it buzzes. Clean the battery posts and battery post connectors and all the battery circuit connections positive and negative cables. Those connections need cleaning twice a year in a 6 volt system and every couple years with 12 volts. Battery fumes cause them to corrode and become resistive.
But it can be that the connections are pretty good and the starter has a short or the battery itself can't supply the starter current. So a good check is a voltmeter testing the voltage on the top of the battery posts. Sharp tip probes are needed to puncture the corrosion typically there. If the posts are dirty the voltage won't change while the solenoid is buzzing. If the battery is weak the voltage will go down and if the starter has a short that voltage will also go down.

Also could be armature solder blown out, causing a dead spot. I'd check that AFTER checking all the above...

why yes if ya have one handy? my tractor normally dies in the field, along way from my tools, I carry a small set for in-field repairs and a volt meter won't hold up to well bouncing around the bottom of my tool box. as Fred in Pa said, start at one end and work your way to the other, it'll take forever to diagnose if your just bouncing around from part to part. definitely don't just start throwing parts at it either. I've seen folks just start replacing parts and end up with a bigger problem. If they get a bad part, now ya have the original problem and a new one and ya still don't have any idea what it is. good luck, dt
