Greetings,
I have two Kubota GL 6500 S units (without the GFCI receptacles) in the field that are working and holding a load, but not functioning properly.
I will give a case history first and what the unit is doing and not doing last.
First off I went to this site to replace an emergency control unit. One unit was in storage at the time while one was online. The unit offline was cannibalized for spare parts as the ECU went down in the online unit. Now both units are online and I replaced the ECU, but the charging light on the repaired unit stayed on.
The charging light (idiot light) normally indicates a problem with the charging circuit. So I checked the voltage on the battery and confirmed the battery coil was not operating. First question that came to mind was "Why did not the ECU kick in to shut off the Generator?" The unit was still operational and held a load. Voltage output was correct.
I decided to swap charge regulators to see if this made a difference. I noted the problem stayed with the unit, while the other unit had no problems as of yet. I traced the wiring down to see if any of the wires were loose. I did continuity checks across the harness to find all wires intact. After that I rested.
Next day I went back out to check both generators. I noticed the problem with the first unit is now on both units!!! So I ordered a regulator and charge indicator just in case.
After recieving the parts I went and installed the regulator and indicator. The problem does persist. I checked the voltage coming from the Batt. Coil 12VAC. The battery is still around 12VDC. with no indication of any charge. My ground stud is still intact and I have a good ground.
I am not sure which way to go. I am limited in parts so I cannot just swap out parts and not worry about it (I am in Afghanistan). I need to pinpoint the problem so I can order the correct parts.
If there is anyone who can help please PM me.
