67Service Manual – SC6000 24 - Electrical SystemTroubleshootingOnboard Charger InterlockIf the Main Machine Controller believes that theonboard battery charger is active, it will disableall machine function, including access to themenu system In the event that the charger failsor was removed, you will be locked out of thesystem menus to change the configuration backto no charger (If removing the charger, makesure to change the configuration first.)If for whatever reason, the machine believes itis being charged when it is not, you will need totemporarily jumper the green interlock wire tobattery-positive The green interlock wire is locatedin the upper-left-rear corner of the battery baybehind the operator’s seatWith the interlock wire temporarily jumpered to B+,go into the Configuration menu and set Charger toNo When complete, remove the temporary jumperBattery TestingA battery problem is usually recognized by the machine operator as a decrease in the machine’s runningtime. This condition is usually caused by one or more “dead cells” in the battery system. There are 2 ways tofind a dead cell:• Use a hydrometer to check the specific gravity (or “state of charge”) of the fluid in each cell. A dead cell isone that reads 50 points (or more) lower than the other cells• Use a volt meter to check the voltage of each battery Look for a battery with a voltage that is 1 or 2 voltsless than the other batteries. Check under the following conditions:– With the batteries fully charged,– With the scrub and drive motors running,– With the batteries discharged, but still above the voltage cutoff thresholdIf the batteries in the machine are more than 1 year old, it’s usually best to replace the whole set, rather thanreplacing one or two batteries Mixing old and new batteries can result in over-charging problemsThe Main Machine Controller also monitors the battery voltage, and progressively disables functionalitywhen the batteries are reaching a full depleted voltage These voltage thresholds will vary depending on thetype of battery installed (configured in the controller). For example, wet batteries are permitted to drain to alower voltage than AGM batteriesGreenInterlockWireConfigurationEcoflexCancel SaveEditOpt PumpBatteryChargerYesNoneWetNo
