Parasitic battery drain on an RT - could it be the Park Brake?

[BLUEKNIGHT911]

Lately this has come up in threads involving dead / weak batteries ...... I got to thinking, the RT needs power to activate the parking BRAKE ...... once set you turn key off and remove it ..... Does it still need Battery power to stay on ?????? .... I'm sure someone really smart can answer this .... Billy ????? ..... thanks Mike :thumbup:

I don't know what electro-mechanical device is employed exactly, but I don't think it's a parasitic drain on the battery or we would have a lot more complaints of dead batteries.

I agree with Pete. I don't think it takes any power once it is set. I know you can't activate or release it if your power is turned off.

Hey Mike!, I’d be willing to bet the switch that activates the parking brake is an electro-magnetic switch meaning once the switch it turned on or activated (as when you press the parking brake button) a magnet in the switch sets the parking brake and keeps it locked by way of a magnet then to release the brake, the same circuit is activated (electrical pulse sent) to deactivate (release the magnet) so the parking brake is released. Others may have better & different ideas


Best,

Not as long as the relay is not powered up. So battery power is not used once the bike is turned off.

And its on the same circuit as the windshield motor

I just starting my 9th season on my original battery and starts up /runs great.

My guess it has to be on either a load sense circuit that reads maximum amp draw or like an automotive power window actuator that the armature shifts after full stroke has been achieved and trips a switch shutting off the motor.

My battery just went dead. Luckily I was at the persons house I bought it from. Got it started and got home. Anyway, I went looking for reasons why it went dead. I found a hard wired mouse repeller. Took that out. I also took out the 4 pin trailer wiring harness. Did these have draw - I'm sure at least the harness did.

I'm pretty sure that sitting behind the pulley that winds that cable is a "worm drive". Push the button, the motor turns one way, tightens the cable and stops when it triggers a relay. Push again, motor turns the other way releasing the cable, then stops by a relay. No power would be needed to hold the brake due to configuration of that set-up.

I think that most battery issues are related to poor connections, poor maintenance, or poor quality materials; "spend up" on a battery and take care of it.

No parasitic battery drain from the park brake. It is a mechanical hold on the disc. Once set it stays on with no power required.
