Battery Tech Tips

(be sure to check the Service Manual for the proper procedures)

 You don’t have to remove the battery boxes or shrouds to take a static voltage

reading with your DMM, simply use the charger port to get a static reading.

 On charge voltage readings can be done with a MKIV Programmer, by going

into the Calibration menu and checking the Battery Quality.

 A Field Load test can be done with a DMM to check the Battery condition.
