Voltage Regulator?

CDR · 03-04-2010, 05:59 PM

Well here it goes..... I have a X2 I can't seem to get the battery to charge. Took the voltage regulator out and tested resistance and it didn't test right so I had another voltage regulator laying around I tested that and it did not test right either but in a whole different way. So I went out and bought a after aftermarket regulator tested it before putting it in and it had all diffrent reads then the other two. I pluged every wire in exsept the hot 12 volt power lead from the battery. I left my fluke mulimeter hooked up to that. ( I think this is where my mistake was.) I cranked the motor over and at cranking speed I saw 4-5 volts which was the first positive sign I have seen. So I started it and the volts went straight up then back down to 0. and I never saw any volts come out of the voltage regulator after that.

Whats everyone's experience with the Kawasaki voltage regulators? Is it that easy to blow one if its not hooked up to the 12 volt hot lead?

I'd bet any money it's your stator... Considering you're having the same issue on two regulators.

Check the pulse lines; are they outputting voltage? (green or yellow wires)

That was my first thought
stator not producing good voltage

But its not the stator is brand new and makes great voltage!

ok...

So now, you had everything hooked up, with the exception of the charging wire to the battery... correct? Are you using a test lamp, or a DMM?

Where to you have the test light/ dmm grounded?

On my first test I had everything hooked up except the charging wire. My DMM was hooked up to the power lead coming out of the regulator and the regulator was NOT hooked up to 12 volt power source.... Upon cranking voltage was present. Once the engine start to run the voltage went to 0 and I never saw and volts after that. Is it possible I blew the brand new voltage regulator?

I'm pretty sure you need to have everything wired up to check it. You measure the volts across the battery, and they should be higher than 13 volts... I have heard that running a charging system while disconnected from the battery can do harm, but never seen it first hand...

As long as he has the positive lead of the DMM hooked to the loose charging wire, and the negative terminal connected to the ground. All you have to do is have a load (the DMM) on the output of the Voltage regulaotr, and you should be fine.

Multimeter's are designed to be as close to zero load as possible! They are meant to allow you to measure various things without interfering with them...

Thats what I was under the impression unless it was one of those very expensive load tester ones.

I swear I think I blew it.... I just never had a Kawasaki charging system problem before so I just can't imagine the voltage regulators are that sensitive.... Has anyone else ever had any problems similar?

True, but it IS a load. And it completes the circuit giving you the ability to read voltage values.

However, as milesinfront stated, it is a VERY minimal resistance. With this being said, you could have possibly had a voltage spike causing the VR to go out.
