Rebuilding a JD730 diesel that has been in the family since new. For the last 20 years it has been started by coasting it as dad did not hook up the starter. Easier I guess. Since I am rebuilding it I wanted to make it right. It had a 24 volt starter on it that was never used that I know of. I took it to a shop and they converted it into 12 volt and I used 2-0 battery cables to wire it up. The starter will roll the engine with the decompression pedal pushed but when you let up it immediately stops rolling and does not fire. I can coast start the tractor and it starts up just fine. I am thinking the 12 volt starter doesn't have enough torque to roll the engine to start. Any thoughts or help would be great. Should I go back to a 24 volt starter or do I have another problem. Should I use a 4-0 battery cable or is 2-0 large enough. Thanks
