Hello all,
Im having a starting issue on my 1969 3020 diesel (s/n 125345r). When I turn the key I get
clicking from the starter relay, but the starter will not crank. My first thought was bad batteries,
so I pulled them out and had them load tested and they both came back fine (2 6v wired in
series). I am mechanically inclined but a mostly self taught mechanic. I have been searching
through this forum for any possible answers, and so far I have replaced the starter relay and the
ignition key switch. Both seemed like logical inexpensive places to start. I grabbed the
multimeter and found that I had 12v at the starter, and I had 12v at the starter relay (I did
inadvertently touch a screw driver across the relay and the starter cranked briefly confirming.I
have power there). I then tested the wire coming from the key switch to the relay and had no
voltage when turning the key. Tested the power wire coming into the key switch in the console
and had power there so figured it had to be the switch. After I installed the new key switch it
started 2 or 3 times but now we are back to just clicking at the relay. I thought maybe I had a
broken wire from the key to the starter relay so I tested continuity and that seems just fine. My
limited knowledge is beginning to run out. Seems like this topic has been covered extensively on
here but I still cant find anything quite specific to what Im dealing with. Can anyone suggest
what I might be able to test next? II would like to try bypassing the neutral safety switch, but am
uncertain how to do so. Any help you can provide would be greatly appreciated. Thank you!
Side note: this last summer we were experiencing a different electric issue. When you turned the
key the starter would engage and the engine would start but then immediately die and lights on
the dash would go out. It seemed as if all electrical was cut. Not sure if it is related or not as at
least we had the tractor trying to start there.
