aftermarket battery

My bike already had the probe removed and the resistor installed so I do not even know what the probe looks like.

Is it an electrical probe or an optical probe?

If it is optical it would have a 45° angled point of clear plastic that goes into the acid. If it is an electrical probe it will have 2 metal contacts that go into the acid.

 

If it is an optical probe you could test it by dipping it in water.

If it is electrical probe, You would need to figure out just how it is being used to come up with an appropriate test.

I can not tell for sure from the service manual and schematics, but I think it is an electrical sensor that is tapping either 4 or 6V off of the battery.

 

Jeff, it is a plastic probe(1"long?) with a carbon/graphite shaft protuding out the end ~1/16" reading voltage of the electrolyte in the cell it is installed, assuming of course that the electrolyte is not at a low level below the tip of the probe. Forget exactly but I believe installed in center cell 3rd from minus, =~6v

Assuming that cell one is the positive trerminal and cell six is the negative terminal. The probe is either in cell 3 or 4, one of the 2 center cells. IF it is in the cell 3, the one closer to the positive side then it is reading 6V to ground or 4 volts to the positive terminal. IF it is in the cell 4 the one closer to the negative terminal then it is reading 4 volts to ground and 6 volts to the positive terminal.

 

So of the 2 center cells which is it connected to?

 

I guess that the easiest test would be to simply take the recommended resistor and connect it between the wire and +12V and if that does not turn off the red light and battery indicator then either the wire is bad or the module is bad.

As you dig in to get the module out, it will be easy to stop and check the wire to be sure that it is good all of the way there.

Excellent idea Jeff! Thanks.

Wire has good continuity so that's not the problem.

 

Some have made reference to "pots" in some of the threads relating to the bypass mod. Are these potentiometers??
