eGator - 3 clicks and no-go when pressing the throttle pedal

Our eGator (#2) started acting up last night - when pressing the throttle after stopping, there are 3 clicks and then nothing. If I press the pedal a few more times, the same thing happens and then eventually it might move on one of the next presses.

The Curtis 1264-5403 controller flashes the 5,3 diagnostic code. According to the Deere technical manual (TM1766), this is indicates that the Motor Relay contacts Did Not Close. So, I guess I'll start with the Motor Relay Test procedure (page 6-73) in the manual and see what is found. Maybe the 3-clicks is part of a retry procedure from the Motor Controller logic if the first application of power to the relay coil does not result in Battery voltage switching through to the controller?

Just wondering if there is any BTDT experience that has also seen this relay fail with the "3-clicks, no-go" behavior?

There are about 1950 hours on this machine from MY2000. We've had it for about 2 months and are enjoying it so far. eGator #1 is still awaiting new batteries, tires and seats before going back on the road/lawn.

Today I found a link to the John Deere Technical Manual for the eGator.

Thought I would share

Parts manual is here

Lithium battery from a Nissan Leaf arrives this week so battery conversion project will be beginning soon.

JohnN, thanks for posting the link to the manual. I had found it before from other sources online, too. It has a pretty detailed troubleshooting procedure, I just haven't had time to step through it, yet, as I've had other projects around the house I have needed to finish, first. I should get to it this Spring.

As for your Lithium batter project, please start a "build thread" and post your progress - this is something I am interested in eventually for the e-Gator!
