BX25D. Mod #1 and continued.

It's 11 volts measured between the alternator output bolt and the chassis. While I realize the alternator will put out maximum voltage at throttle, I don't know what it should be at idle. However, 11 volts doesn't sound right to me (wouldn't I be essentially draining my battery with my accessories powered on?)
Thanks for the help!

Yes, a fully charged battery is around 12.5 volts, so a alternator putting out 11 volts will not charge the battery.

It's good to hear from you and happy new year!

The Arctic blade has been working *really* well for me. I'm extremely happy with it, and I would recommend it in a heartbeat to anyone. I'm really glad I learned about it after seeing the Arctic installed on your L40, otherwise I probably would have never known about it. I also posted a few pictures in the snow removal forum of TBN in case you haven't seen them yet. Hopefully, I can take a video of the blade in action during the next storm (been meaning to, but I'm usually in too much of a hurry that I never get around to setting up the camera.)

As for the L4760, it's a been really great (I've put just under 40 hours on it now.) There are a couple minor issues that I'm dealing with at the moment. The new bucket level indicator system on the L60 is prone freezing the rod in the sleeve assembly if not *well* lubricated (I should probably create a thread about this to warn folks.) I ended up finding out about this the hard way and broke the pivot bracket in two places during the first snow storm we had. Luckily, I still had my welder setup in the barn, so I able to quickly remove the bracket and repair it so I could keep plowing. I have a new bracket on order since the original bracket was badly deformed from the LA1155 loader, but it's backordered until end of Feb.

The other issue I've been dealing with is a low voltage problem where the alternator appears to be only putting out < 11 volts at idle. The tractor is at the dealer now, but they haven't been able to reproduce it. In all fairness, the issue has been intermittent for me as well. Although, I'm really hoping they can figure it out what's wrong since it's been driving me nuts while I'm out plowing at night. The radio either cuts-out (when the flashers are on it goes on and off in sync with them) or just stops working altogether when too many things are powered on at the same time. Otherwise, I still really like the L4760 and I'm very glad I decided to move up to the L-series.

I'm sure all the snow fall has been keeping you very busy. Do you still have a lot of snow removal contracts this season? Glad to see you still have time to work on these cool mods. It's still one of the main reasons I keep coming back to TBN to see what else you've come up with! :thumbsup:

Just checked out the photos on your thread and they are FANTASTIC! You got the set up there now buddy, not much you won't handle with that beast.

Like anything a Newley designed machine will have a few things that needs to be tweaked once it gets out in the real world and I'm sure it will get sorted out. It's just a pain having to bring it back to the dealer and not having safely at home.

Now let's talk about your voltage issue. First off all IF your radio is cutting out when the flashers are on then it's my opinion it's a ground issue. I've don't a lot of electrical repairs over the years and I've always said that if you got stuff going on electrically that looks like it's processed by sprits then look for a bad ground.

That being said. If you have everything turned on at idle such as the heater heater (up on high), wipers, defog there's no way the alternator can keep up, it WILL go in discharge mode. The only way to have all of these items on and to be able to keep up with the demand is to step up on the throttle.

Now if your only getting 11 volts at idle with nothing extra running, example heat on low and radio on then I'd suspect an internal issue with the voltage regulator and just maybe that's where all these electrical issues are. That would be where I'd be looking anyway.

Well it's been a crazy winter so far. Record snowfall, actually the most snow since 1901 for December. To make matter worst we've been having major electrical outages island wide. Sure happy I put in a back up generator last fall. It's been a great comfort having it.

Keep us posted on what they find you you new machine. It's a beauty!

Lots of snowblower footage in this video!

Wowww! Snowww! Love seeing the toys working. Since I have chains now for xmas.... no snow anywhere in sight here

It looks to me as if you have wheel weights on your tractor. Are they a Kubota product or your fabrication?

I saw the two tractors and thought it looked like Papa Tractor and Baby Tractor, and was wondering where Mama Tractor was?

Very nice mod I bet it makes swapping out a breeze. I have one on an excavator makes life easy. Always nice work.

I see the 60 series alternator is only 60 amps. Strange that with all the new electrical consumers on the tier 4 engines a 60 amp would seem minimal. Most likely if there is not an issue with his regulator or alternator then maybe a pulley change to speed it up is in order. I suppose could be a problem that Kubota has not figured out yet? Makes little sense. Maybe the idle speed needs bumping up.

Anywho I do a pile of battery, charging stuff and 12.60 is a fully charged battery (no consumers on engine off), 12.5 is around 90% charged.
I have a couple trucks I don't use much and occasionally use a maintainer to bring them up, while the older Kubotas don't have any parasitic loss while at rest most vehicles do drain up to 40 milliamps which will kill most normal sized batteries in a month.

A quick test on your resting tractor would be simply looking at the battery voltage with a volt meter. 12.6, 12.6, 12.6 all the way, if it's less it needs charging. Any of us that run electric snowplows know the importance of a fully charged battery.

I fooled with some testing when I installed a Vette LS2 engine in an older Volvo. The engine idling would draw 7 amps, under wide open throttle burnout conditions at 6700 RPM the engine draws 60 amps just in coil current and fuel injectors, pump, etc. What an eye opener, surely older Diesels don't consume this much, I guess my point is why wouldn't Kubota go with a larger alternator on these new machines?

Regards, Fred
Sorry to jack.

My friend, you pay the shipping and I can send you enough snow to keep you busy up til July :laughing:

Those are Kubota wheel weights. They are stackable and they weigh 220 lbs each. There are four back there. Momma tractor can show up here any time

All good accurate points Fred. When it comes to battery tenders or automatic floating trickle chargers I keep one on everything I have a battery in. The battery in my GoldWing is still the original since 2003. Don't you worry about highjacking this thread. This is kind of a anything goes thread at this point. How did your tractor work out?
Great hearing from you :thumbsup:

The turbo works flawlessly so far, thanks for asking.

The amount of snow at your place reminds me of all the snowmobiling I did in and around the Gaspe region of Quebec. Big storms can be the norm there.

Great to hear it worked out for you Fred. You did some nice work on that project, Tip my lid to you on that. Oh man. I drove through the Gaspe region of Quebec many times heading towards Labrador City. Nice area both summer and winter. Out of all the toys I've ever owned the snowmobile was my favorite.

Hey Paul, did you stop doing snow removal for others? I know you talked about it but with the record snowfall this season I was wondering if you decided to plow or not. Of course that would be extra income for you. Just curious. Thanks, Stanley

 

[varmint]

Paul, I live just down the road from Stanley... I guess us locals here are all curious why you aren't out all night, snow-removing for fun and profit? Though it looks like you got enough right there at home to keep busy!
