Re: removal of generator from LGT16D tractor

 

I'm not familiar with these modern units with alternators. I'm from the starter/generator days.?

With that said, I would try the following: Attach a voltmeter to the battery terminals. Not running, if the battery is good, it should read 12.6 volts. With the engine running. I think it should be around 14 volts or more if the alternator is charging the battery.

If I've said anything wrong, somebody please correct me??

I took the old regulator, the 6 terminals were corroded and dirty. Took a fingernail emery board and cleaned/polished them up until they shined. Put the old regulator back into the tractor, started it up and there was no dashboard light on. I'm guessing there's only 2 possible outcomes here, either the light was on and unit was not charging or light was off, signifying charging was in progress?

The 6 wires on the new regulator were not in the same sequence as the old regulator. I would guess colored wires would signify the same function on both regulators, but I could be wrong on this.

There's 2 wires coming out of the alternator, could I test these wires to see if I'm getting juice out of the alternator?


thanks again,

Mike

You might also try gluing a strip of 240 or 320 sandpaper to a strip of veneer.

Also, with the covers off both regulators check and see if they look like they have the same wiring configuration.?

Virtually all of the 6 contacts were very corroded on the old regulator. I might be able to use a fingernail file with the sandpaper surface to clean up the terminals. Thanks for the suggestion,

I suggest that you carefully sand the contacts on the old regulator and put it back. With cleaned contacts it may work properly.

I've replaced my voltage regulator on my LGT16D and now the dashboard
light is lit, signifying that the battery is not being charged. I?
installed a knock-off regulator, not the OEM, and I'm wondering if the
new one is just different in its wiring configuration.

If anybody has either the 14D or the 16D, can you tell me if you've
replaced your regulator and have any of you experienced this problem I'm
having.? I don't have the wiring diagram for this regulator and the
wires/plugs, I believe I've wired it back together correctly.

Any thoughts on this?

thanks to all,

Mike
