the battery terminalsSteven's Instrument Model NoLB-85 and Snap-on Model NoMT540D are examples of testers available i causing
electrolyte gassingThis might create an explosive atmospherer,1 5Start the engine and run it at approximately 4500 RPMUse
the variable load tester to draw the battery down at rate equivalent to the stator's full output "'" Excessive battery discharge
rates might overheat battery 6The engine's ammeter should indicate full output12 amps Decrease the battery load toward zero
ampsThe engine's ammeter should show reduced outputAs the current draw decreases, the battery voltage should stabilize at
