B2920 won’t start

[gimmodog]

solenoid should have 12 volts and the BW wire terminal from the safety switches with the switch in the on position and should have 12 volts on the BW wire terminal from the switch in the start position IF it has the 12 v on both then it is bad if not from the switch then look into the switch

don't forget the starter relay, they can go bad!..

Thanks! How do I check the starter relay?

there needs to be voltage on one terminal of the coil, ground on the other in START position. and the contacts have to have voltage on both terminals in the START position. the relay supplies the voltage to the starter solenoid when in crank position, but you are not getting that..

the starter relay is what I was calling the solenoid. Test are in the guide I posted. on schematic is call starter relay.

relays and solenoids are 2 different things.. on his tractor, the starter relay activates the solenoid on the starter..

Can you guide me on where the starter relay is on this tractor?

I never worked on a B2920 so I don't know its location. If you follow the BW and BR wires they should lead you to it. Maybe radios1 knows the location. sorry I kept calling the relay a solenoid. Your friend that is helping you should be able to find it and follow the test procedures.

sorry. I can't find a picture or description of where it is, it's probably in the repair manual for your tractor, it's not even in the owners manual..

My 3cents... Messicks or Kubota online, under parts, and then into parts breakdown diagrams for your tractor under 'Electrical System'. (Example, there are several on my "L" series) . I started at the top Electrical diagram and went thru each on the Electrical parts breakdowns, then in the lower half, scan the detail (or use Ctl-F in browser to search for text) and look for key words . I quickly grabbed a screen and pasted it below. In there are many elements and the locations. Sounds long but took 10mins. There were 4 or 5 links.

And... Messicks (or other.. pick you fav place... Not pushing one over the other.. it's just who I use). Their online service staff for parts will pull these up too and get you an answer. Even pulling in someone to help you get to the part you need. YMMV
