What will a bad voltage regulator do on a snowmobile?
A: Flickering lights followed by loss of electrical power is a common problem on Polaris sleds from this era, usually caused by a failed voltage regulator. Voltage should not exceed 14 volts, but with a blown regulator, it might show 14 volts at idle. If that’s the case, the regulator needs to be replaced.
How do I know if my voltage regulator is bad on my snowmobile?
Measure ac volts across brown and yellow wires. As you rev it up the reg should clamp it at 14-16 volts or so. If it’s blown, you will burn light bulbs out. It just dissapates the “extra” voltage ,clips the tops of wave form.
Can you run a snowmobile without a voltage regulator?
are disconnected or you’ll blow them out. That stuff is still hooked up to the stator lightning coil and is active once the motor runs. OK, the lights and the VR are not hooked up, so it should be fine, right.
Can a bad stator ruin a voltage regulator?
Can a bad stator kill the Regulator/Rectifier? —-Yes. That is “yes” from an absolute standpoint. Normally no and less likely with the “Y” wound stator used in the DRZ, but yes it is possible.
Will a sled run with a bad stator?
As I understand it, the short answer is no. Your problem would be the lighting coil. If the stator is bad you’re not going to run or have lights or anything though these symptoms my be intermittent or progressively get worse.
Can a voltage regulator cause starting problems?
A bad voltage regulator may cause it to simply not work or behave erratically. You’re not likely to be able to start the car at all, but even if you could, it wouldn’t be wise to do so without knowing how fast you’re driving, how much fuel you have left, and other critical info.
What controls the voltage regulator?
A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier. It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage.
