Hey guys,
The KH400 that I recently built is giving me some issues. The bike came with these problems so I don't know what the root cause is.
Here goes:
Symptoms:
Drains battery while running - Voltage 4.3V
Neutral Wire starting to burn near the cases
My work so far:
Re-wired all of the lights - From harness to the bulbs (work just fine)
checked all the wires in the harness for continuity - A-OK
Replaced AC Generator
Replaced Voltage Regulator
Did a diode test on Rectifier and seems to work properly
Checked and cleaned all the grounds (battery, cases, harness, coils, signals, controls etc)
I may try source another rectifier to tryout but before I spend the money are there any other tests or things I should look at?
Thanks!!

The Kawasaki manual has a test procedure for the regulator and the rectifier. You can test the rectifier with a meter that has a diode test setting, instead of using a resistance range as the manual tell you to. A resistance setting is not likely to work with a modern meter.

I couldn't find a KH400 Manual online but I did some research and was still able to find test procedures.
For the rectifier I did the Diode Test with my meter and it checks out. I got the same signal (around 750) on both yellow wires and then I changed the polarity I got no signal which I believe is correct.
On the Regulator I did a resistance test. I had my meter set to 2000 and was getting a result of 1130 Ohms. I did the same test on 2 other regulators with the same result.

Does it blow fuses? I ask because I chased a problem on my S3 for the longest time and it turned out to be a bad rear brake switch - it was somehow allowing current to flow.

Thanks, I could only find the Kh400 Assembly Manual but I'll look again |
