I'm trying to find out the battery hookup for a Merits S549 Scooter; had to replace the batteries and want to make sure I hooked them up correctly

hi, normally 9 flashes means controller failure but can be caused by a bad connection.

Locate the controller and refit all connections but i recommend removing a battery terminal lead first.

Regards

I can't help you with this, but it appears that there is power there based on what you say. I would be inclined on taking this to a mechanic to get this looked at because it may involve a motor or a switch.

turn the speed up some, unplug Charger, put brake lever in drive mode - hard to push, restart with the key. make sure no damage has happened to the wiring harness that connects to the back. Circuit break may need to be pushed in. this is a start. Next thing would be the Throttle and speed pot.

You can call Tech support at Merits 800-963-7487. owners manual may have where the fuses would be. Lights could be burnt out. more likely the wires were disconnected.

it appears to be 94 lbs. Base 54, Seat 18, Battery 22.
Capacity = 300 lbs.

Going and Slowing is usually a problem with the throttle pot. They are often easy to fix yourself with a bit of WD40 once you have found out where the throttle pot is on your machine. Sometimes they have to be replaced, but fortunately the part is quite cheap. You didn't say what brand your scooter is, but Pride scooters are known for throttle pot problems.

Make sure the connections are on correctly!
