Battery Warning Light Help

[JayLaveroni]

My battery warning light will not go out. The manual says to check the fluid level. The level is fine. Anyone else with another suggestion?

[Dano]

Check the connection where the sensor plugs into the wiring harness, may be some corrosion in there not allowing the signal to transfer. Also make sure your electrolyte covers the sensor as it's installed. Short of this being the problem, you could get rid of it by soldering a 2 ohm resistor in line.

I would first take the wire that goes to the fluid level and put it on the positive side of the fuse box screw. this is while the bike is running and see if the light goes out, then you no if you need a new sensor or you can do the battery sensor mod to it. You have tested the battery to make sure the bike is charging and your getting the right voltage.

If you hook the sensor wire to the "hot" screw on the fuse panel, you blow out the detector chip in the dash monitor... You REALLY want to use a 2.2k Ohm resistor in-line to the "hot" to "simulate" a good battery.

Then you can finish the mod by adding an Odyssey PC680 battery and those nice 4 gauge cables.

I just put in a PC680 and I like it!!

I've put in the PC 680 as well.

As far as I'm concerned, there is no other battery to consider.

Like Dan said, go with the resistor. I had a brand new battery that tested fine, but it wouldn't make the warning light go out. Evidently those things are very sensitive to even a little bit of variance from spec.

Ijust purchased an 86 VR and my battery light came on. It was due to a blown fuse.

Which fuse was it ??

[Relaxin]

Which fuse was it ??

 

It was the ACC fuse.

[GeorgeS]

The battery water level sensor is Not on a fused circuit, it simply sends a voltage from the battery sensor to the Instrument panel.

 

So, I was curious as to how a fuse would cure the problem

 

The " Accessory " Fuse is provided by Yamaha, so users can hook up any Added Accessory they might mount on the bike. Normaly its not used.

 

So, sombody must have done the Battery Sensor light, modification, and used the Accessory Fuse, as the Voltage source, for the Modification.

 

So, just to be on the safe side, Follow the output wire From the Acc. fuse, it should run to where the a 2200 OHM Resistor, has been added in series, and hooked to the R/W (Red/White ) wire that "Used to " go to the Battery Water Level Sensor.

 

Also, you must have a " Sealed Battery " Installed. Right ??

 

Whats my point to all this ? Nothing, Just an Old, Electrician , mulling things over ---

[Relaxin]

You are GOOD George. You are absolutely right. I do have the sealed battery and the battery sensor light mod is tapped into the acc fuse. I was a bit confused when the battery warning light was on and it involved the acc fuse. As you can see I am NOT an electrician... shocking, huh?

Semper Fi,
