How to Start the Battery for a Yamaha 150 Four Stroke
- 1). Park the Yamaha 150 on level ground. Remove the bolts from the rear left quarter panel using the ratchet set.
- 2). Pull the quarter panel off the frame of the 150 and set it aside. Connect the corresponding cables on the charger to the connections on the battery.
- 3). Turn the battery charger's power on and set it to charge. It will probably take around two hours for the battery to fully charge.
