Just last week, I found out that when I turned the key on the Sunstar 20, dash lights up but no cranking of the engine. I jumped the solenoid poles and it cranked over and started.
Well, that is not a good long term solution so I replaced the solenoid - not much labor involved and a solenoid is only about $9.
Yesterday, I started the tractor and drove it around to the other side of the house. I let it run for a few minutes and then shut it down.
An hour later, I went to move it but again, no crank. What the.....
I decided to jump the solenoid poles again - and it started.
What are the chances that a new solenoid has gone bad after only one time use?
Is there something deeper that I should be looking into?
Is there a common electrical issue that kills solenoids?

As I ponder this problem...
It occurs to me that I had starting issues that were fuel related and the battery got pretty low from all the cranking. Maybe the low cranking amps killed the solenoid?
I will replace the solenoid again but I will be more careful about the battery level.

When you go to start it do you just get a clicking? Probably nothing more than a dirty connection or corroded safety causing the issue. See my signature for a video that may help you with your problem.

Jumping the solenoid will bypass the safeties, not a good idea. It will even turn the engine over with the key in the "OFF" position.

There is no clicking. Just lights on the dash and nothing else.

I am becoming convinced though, that the solenoid is probably OK.

So I will have to track down the other issue.

MD Stout....which fuse?...is there a starting system fuse in that tractor?...also let's go over basics.....PTO in off position, foot on brake, someone in the operator's seat?

The relay assist that BoWoggie suggests was "invented" by Brad....one of the other moderators on here, ( see post #5 in this thread...that is Brad) and it does perform a miracle on problem starting...have you performed a load test on the battery?.. I would do that and make sure you are not dealing with a weak battery ....I would disconnect, clean and reconnect every wire and cable connection...start with where the ground cable attaches to the chassis

The solenoid needs to be grounded. Has the ground been checked? Just bolting it to melt does not insure a good ground.

Believe I would suspect either a weak battery (that's dropping voltage under starting load, causing higher current) or a starter that's binding (dirt, low lube, etc.).

I will look into it again come spring. For now, the battery is in storage on a trickle charger for the winter.
