Hello to all . I was hasty in passing on my findings and someone replied to me about posting in the wrong area where it gets little reading. Okay , hopefully this time it will be different.
The issue revolving the kubota B2100 starter clicks is a relatively simple problem , yet I have seen months of exchanges on various posts all over the net , people with good intention steering others in the wrong direction .This post will be worded differently than my previous which I could not successfully copy and paste here .
I am an instrumentation engineer , I design circuitry that employs both ac. and dc controls .
A wiring diagram of the B2100 tractor is the first must have , in it, one can see the problem immediately , it is an over used IGNITION SWITCH , since there is no intermediate relay between the start contacts of the ignition switch and the positive post of the starter relay known to many as the "solenoid" ( "a trade name ") .Over the years and too many start stops , arcing occurs that over the years build up resistance and only allow 8 to 9 volts at the "solenoid" which only partially engages ..the clicks which the orange lovers hear is only the partial engagement not the full it must have in order to allow voltage to the starter motor brushes.
With repeated attempts to start the engine , the additional arcing and the amperage heating which occurs at the ignition start contacts will get rid of just enough oxidation to allow full voltage to reach the starter motor and magic ! IT STARTS then starts okay all day until next day or next week.
Obviously a decent battery , clean terminals , positive cable and negative cables free of corrosion should be high on the routine maintenance list. Another is the charging system , a properly tensioned drive belt and a dynamo that puts out 14 plus volts dc after it is rectified from out of the rectifier, which is located under the instrument cluster practically under the tach.
Other very important items are the chassis grounds , The B2100 has three , the battery cable , the ground grouping located on the engine aft of the injection pump, the ground grouping under the seat.
I strongly recommend to all to buy a spray can of Detox electrical contact cleaner . The replacement ignition switch will get the job done by itself but while you have the tractor down it does a lot of good to separate and detox each molex plug [ all of them ] each engine sending unit lug and spade connector , in other words every electrical connection , I did it in under two hours..the starter is the original 1997 mitsu and it is strong enough to flip the tractor over.
So, get a service manual , electrical diagram is a must.
Replace the offending IGNITION SWITCH, service the rest of the electrical system anyway irrespective of the fact that your tractor now starts fine , it is worth doing .
Now that you are done , at your earliest convenience invite a friend over for a favorite brand of beer or other beverage , start a nice backyard fire and toss the offending old switch in the fire ..be sure the fire is hot enough to smelt iron ore and enjoy the show, it may make up for all of the aggravation it has caused you , I had fun melting my old switch , I am no longer upset !!!
Have fun , happy starts to you all .
