Why does my voltage regulator keep going bad?
They usually fail because they’re under rated for the constant current draw. Running the motor with the battery disconnected – or even a poor contact on the battery terminals – can also blow them.
What kills a voltage regulator?
A shorted battery cell will kill the alternator, or regulator if you run the bike. Check for a bad battery negative cable.
What are the reasons that a regulator can be burned out?
Regulator fires can occur when gauges are accidentally used for the wrong types of gas. Such misuse increases the potential for contamination of the regulator. Use of a contaminated regulator with high-pressure oxygen can result in a regulator burnout.
What causes a voltage regulator to overheat?
Why is the voltage regulator heating up? … The greater the difference between input and output voltage or the greater the current, the more heat will be dissipated by the regulator. This means linear power regulators are not very efficient at regulating voltage, since so much energy is wasted as heat!
What are signs of a bad voltage regulator?
Symptoms of a Bad or Failing Instrument Voltage Regulator
- Dim or flickering gauges. One of the first symptoms of an issue with the voltage regulator is dim or flickering gauges. …
- Inaccurate or erratic readings. …
- Inoperable instrument cluster.
What is regulator burnout?
Regulator Burnout is what happens inside an oxygen regulator when there is dust or other debris and the valve is turned on quickly. The dust or other debris ignites because when the oxygen cylinder valve is turned on quickly, both pressure and temperature spike for a microsecond in a pure oxygen environment.
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.
How do you reduce heat from a voltage regulator?
The ways of reducing heat dissipation in the regulator are: (1) Use a switching regulator such as the NatSemi simple switchers series. A performance switching regulator with even only 70% efficiency will reduce the heat dissipation dramatically as only 2 Watt is dissipated in the regulator!. ie Energy in = 7.1 Watts.
Why does a rectifier get hot?
It’s normal for an OEM shunt-type regulator/rectifier (RR) to get quite hot — especially when the load being drawn by the electrical system is low. The RR is simply converting excess stator output wattage (that isn’t needed to run the bike and charge the battery) to heat. That’s why there are cooling fins on the RR.
Does a regulator rectifier need to be grounded?
The R/ R does not need to be grounded or bolted. It will work if you were holding it in your hand. Adding that the R/R is grounded through the wire harness. If anyone is having a problem check the connectors and the grounds.
