B6000E Wiring Question

JoelD · Oct 7, 2007

neither my lights nor my horn work.
Can anyone give me a starting point on diagnosing?
I've got the wiring diagram.

One thing I'd like to figure out is how to test the dynamo (generator), it's got three wires off of it and the manual does a crappy job of telling me what each should be doing? There is a rectifier, so not certain if the the dynamo is only putting out AC or both AC and DC.

Any help is greatly appreciated.

Sincerely,
Joel

My B6100 has a fuse behind the steering wheel cowling. It was broken on mine. I think it feeds the horn and lights. On the dynamo, check voltage at the battery with engine off and then started at a decent RPM. You should see a couple volts higher when running.

Thanks mike,
Ended up being the 5 amp fuse, there are two, one to the fuel pump which is 3 amp and one to the horn and lights which is 5 amp. I did not have good continuity through the fuse although did not look outright blown. Replaced fuse. Then found I did not have good ground on the lights, so direct grounded them via wire fittings rather than through hood, all is well.

Will test dynamo output this weekend.

Any idea what each of the three wires from the dynamo do?

Thanks,
Joel

You can go to this post for some info on charging voltage: http://www.tractorbynet.com/forums/...6681-d650-dynamo-thingy.html?highlight=dynamo This post has a diagram of the wiring for mine, yours should be similar: http://www.tractorbynet.com/forums/kubota-owning-operating/106681-d650-dynamo-thingy.html

Thanks, diagram looks at first blush to be identical to my wiring diagram. Just not certain how to read the three wires coming from the dynamo? I am guessing the one going to the rectifier is AC which is being converted to DC by the rectifier? (my lincoln welder has a rectifier, I think that's what it does).

I am having trouble understanding what readings I should be looking for from each of the three wires out of the dynamo, my local Kubota dealer has a B6000 wizard, I'll try to see if he knows.

I appreciate the time put into your posting the link.

Sincerely,
Joel
