B6100HSTD electrical issue

swierczt · Feb 14, 2016

I am having an electrical issue with my B6100HSTD. I plowed snow with it a few days ago and noticed the lights starting to flicker. I thought maybe bad ground or loose wire so I shut them off and kept on plowing. I put the tractor back in the garage and turned her off. I went to start it again several days later and she would not crank. No lights, no ticking of the hour meter..no electrical power at all. I checked the battery and had 12.5V. I had the battery checked at AutoZone and they said it was fine. I thought maybe bad starting key switch so I replaced that. Still nothing. I then replaced the voltage regulator. No luck. I replaced both battery cables and terminals. Nothing. I can put a wire directly from the positive on the battery to the lights and they will work. I have also put a wire from the positive on the battery to the wire on the starter and the starter will crank. All the fuses I could find are good. I used the wiring diagram from kubotabooks.com for a reference. Most of the wiring was close, but not exact (the site only has a European book). I'm not sure what to check next.

Use a meter and check to see if there is power to the switch and the light switch. Look for one more fusible link. It may be in line and not in a box.

Electrical is right towards the end.

Thanks for the reply. I have power to the key switch, and when I turn the key to the on position, I have power to the 'AC' pole on the key switch. I have power to the flashers, but not the lights, glow plugs or starter solenoid.

a relay ?

Seems you have narrowed down the search area.

Can you tell if there is power on the outlet side of the switch. If so you've not far to go.

Fusible link on line to those functions that have no power??

No relays except for the flasher. I still haven't found a fusiable link anywhere. I'm wondering if it's something in the dynamo?

The Dynamo should not show up except not charging the battery. Are there any safety interlock switches? The clutch pedal comes to mind.

There is a switch for the clutch petal, but even if this is not engaged, I should have lights and the glow plugs should function. The clutch petal switch is in line with the wire to the solenoid on the starter, if the switch does not make, the starter won't crank.
