kubota l3400 start issue

[jedwa1216]

My Kubota has been having starting issues for a year or so. It finally has got so bad (wont start 80 percent of the time) that I have to figure it out.

I have replaced the battery and ignition switch but neither fixed it. The start relay tests good. I have been searching for bad connections but no luck.

I have found that when I turn the key to start, battery voltage drops from 13 to 8. This also happens when I read the voltage at terminals 2 and 4 on the start relay with the key at start.

The safety switches and circuits all test good. Any help is appreciated.

Sounds like it could be the chassis ground. Have you followed the ground cable to the location on the chassis and ground or sanded the cable terminal and grounding area clean?
