GF1800 Wiring question

[TimAT]

The previous owner removed the dynamo and installed an internally regulated altenator. No idea what the output amps are. I'm guessing more than the OEM dynamo. Regardless, it is charging the battery per my handheld voltmeter.

The charge light on the dash does not work. Does anyone have a wiring diagram that shows how to hook it up so the light function is restored? The OEM IC regulator is unplugged and a couple of jumper wires are installed on the machine side of the regulator plug.

Thanks I have the WSM. No info on the alternator conversion

I got my hands on the installation instructions for the B7324 conversion kit. But no diagram that shows the wire diagram. Instructions only show how to route the harness.

From Googling 'Kubota B7324', it appears that kit also fits the B3030 and other tractors. There is a WSM for the B3030 at kubotabooks.com. Does your alternator have RY (red w/yellow stripe) and WR (white w/red stripe) wires and internal regulator? If so, it looks like the charge light should be connected between those two wires.

Thanks.. Very helpful. at least I know how it is supposed to work. My alternator is at the hospital right now, should have it back in a couple of days. It is an internal regulator type. Chasing the wires, the original sky blue wires from the dynamo have been used to get the field and the sense wires to the dash, and the alternator output is directly to the main battery terminal on the starter thru a 50A fuse.

Update: I found this thread about the Dynamo to Alternator upgrade.

Alternator Upgrade - B7311/B7324 Options

B2301/B2601 Alternator Upgrade - B7311/B7324 Kit Options One of the things that was frustrating me was the lack of information on upgrading the alternator on my B2301. I know that the B2301/B2601 are essentially the same machine (except HP), so nearly all parts are interchangeable. They both...

I had all of the parts required except for the 4 pin relay, so I used a 5 pin relay and socket, just cap and stow the extra wire off the relay.
Now the charge light works as it should. I did add this diagram and parts list to my GF1800 WSM for future use,
On to the next little project.
