What Is Wrong With The Lawn Tractor Batteries:
First some background. I own a '99 JD 345 and a 2013 JD Z710A Ztrak. I'm a one owner on the 345 and I know it's history. Yesterday, I was mowing around the wife's flower beds and ran out of gas. Didn't have any in the garage, so, I had to make a trip to the service station. When I returned and refiled the tank and tried to start, it made a few starter turns and quit. Nothing. no dash lights came on and no fire to the coils, to starter solenoid. Knowing past problems with a 345, it is the infamous "Time Delay Module" or the "Interlock Circuit Board" which is famous for a "no start" on a 345. With some help from a neighbor I got the tractor back in the garage to be checked out.
If any of you members here own a JD 345, it is wise to have a few extra parts on hand, like a TDM and Interlock Circuit Board, which I have. I first installed a new TDM, same "No start" nor any dash lights, and no voltage to the coils, and starter solenoid. So, I installed a new Circuit Board. same "no start" or dash lights. Well!. lets check the battery voltage. 12.7 volts it shows. So, I removed the battery and put it on a charger for about two hours. Re-installed the battery and BANG. tractor fired right up as it should.
So, here's the story on the battery. It's a Exide brand and it is 9 months old. In March 2018 I bought a Exide Model 51C from Tractor Supply. In October 2018 I had to replace the Exide battery due to low voltage and a "no start" on the 345. This Exide #51C is the replacement on from Tractor Supply. It appears to have failed the same as the other one for TSC. Over the last thirty years I've never had any problems with Exide batteries like I have the past 1-1/2 years. It may be that Tractor Supply is buying Exide culled batteries
