OK so I have the red warning light flashing and the battery icon lit. PO said it was cuz he installed an aftermarket "maintenance free" battery which does not accept the sending unit for electrolyte level. Read the thread explaining how to bypass with a resistor. Tried both 1k ohm and 2.2k ohm resistors with no success. Ayone have any other suggestions?

Originally posted by "Squeeze" In cold Conditions, and if you use a Standard Lead/Acid Battery, i recommend, before Starting the Engine, leave the Lights on for 30 Seconds. Seems to be stupid without Explanation. It is not ... The starting Power the Battery is able to give ist in direct Context to the inner Resistance of the Battery. If the Acid is cold, the Resistance will be high, e.G. 10 Ohm. If you start the Bike right away, the Resistance in the Battery is much higher than that of the Startermotor. The Startermotor ist in short Circuit in the first Moment of putting Current on it. As the Startermotor starts to turn, the Resistance rises to the normal Level of about 2 to 4 Ohm. The Resistance of the Battery with 10 Ohm and the Motor with Zero or maybe 2 Ohm, is much more a Batteryheater than a engine starting Subsystem. The Power of the Battery gets lost while heating and cranking the Engine. If the Engine doesn't start right away, the Battery power gets weaker and weaker, even if it is now heated with own its Power. There is no more Power left to deliver to the Starter. If you put on your Lights first, the Battery will have the same starting Resistance, 10 Ohm as i said. The Bulbs have a much higher Resistance, so, the Bulbs will shine and the Battery gets also heatet but not that quick and not that energyconsumpting as a failed starting Sequence will have used. The inner Resistance of the Battery drops down on warmer Condition inside the Battery. 30 Seconds later ... Voila... press the Button and the Starter cranks more powerfull, because this Circuit isn't a Batteryheater anymore. By "preheating" the Acid, it is more Capacity awakened as the Loss by the Lights is. The 10 Ohm as the inner Resistance is not the correct Value, it is just for explanation and better Understanding of the System. In Fact the Resistance is more 1 Ohm than 10, anyways, this tiny Trick works on all Lead/Acid-Batteries for sure. Cars, Bikes, Trucks ... Might also be helpful on Batterytypes, but not that impressive, because other Types have a way smaller inner Resistance by System. This is not my idea, i did learn this Years ago, when i was 3 Days send to a Battery manufacterer for a 3 Days Seminar. __________________ Life's too short to have bad Drinks ....
