Kevin has DTAC access, I will alert him you your thread...
Electrical problems can be tricky to troubleshoot, I wish you luck GotDeeres.Tackit,
The strange thing is the voltage is lower when the tractor is started and gradually INCREASES. Normally the voltage is higher when the tractor starts to recharge the battery and then reduces as the battery is charged.
I have a Tektronix TEKDMM155 which is a very good meter, but I also tried my Fluke. Never assume anything when trouble shooting. It is strange that two tractors and three voltage regulators have the same result?? I will figure this out!! :dunno: It is just a matter of time and money. Since I am retired, I have plenty time, but little money.
