Step 1 – Is the charging chain good, and is there a green light on Base Station Head?
If Yes – Proceed to Step 2.
If No – Check to ensure the charging chain is getting a good charge through the live wall outlet, power supply, extension cord and Base Station Head. Pull the mower out of the Base Station 1/2 inch while it is still charing. Using a voltmeter, make sure that the Base Station charging horns supply a healthy 33-34 VDC. Replace any non-functioning parts as needed.
Step 2 – Keep mower on the Base Station and just turn off its safety/main switch. Let it charge for 30 minutes, and then turn the safety/main switch to On.
If battery voltage reads below 16 VDC, Replace Battery and allow mower to sit in the Base Station until fully charged.
Does the display come on and stays on steadily?
If Yes – Keep charging and mowing. Problem solved.
If No – Proceed to Step 3.
Step 3 – This is probably a low charged or bad battery. Take the mower out of the base station. Remove its cover. Turn mower’s safety/main switch Off. Remove the fuse. Unhook the battery at the white connector plug and check battery voltage with a voltmeter on a DC scale higher than 20.
Is battery voltage lower than 16 VDC?
If Yes – Replace Battery, charge it and mow as normal. Problem solved.
If No – Proceed to Step 4.
Step 4 – Inspect the main fuse harness. See if all wires are hooked well and are not broken, browned or burnt. Is the harness okay?
If Yes – Proceed to Step 5.
If No – Replace main fuse harness and fuse housing (all one part).
Step 5 – It is recommended that you Replace the Main Board.
Did this resolve the issue?
If Yes – Problem solved.
If No – Consult with level 3 technical support.
