T300 will drain battery and will not fire up start engine panel in cab.
So, New battery, cranked for a few days then same deal, it discharges battery over couple days.
checked alternator, its good, ( pulled and took to shop to make sure )
took new battery to napa, it checks good.
what is weird, is even with a fully charged battery now , it will not light start panel up , but if I hook just a little battery charger up , 6a amp for 10 seconds, it will light panel up and start engine.
Im getting 12.8 volts at starter, almost 14 with charger hooked up.
I ve swapped out relays and checked all fuses in panel in cab.
alternator is showing charging good while running
so, something is robbing voltage from battery to panel used to start engine in cab, and also draining battery while not in use.
after it runs a while , it charges the battery enough it will shut off and restart without the charger.
appreciate any help,
