Sounds like TPS is still having issues.I have been doing apps reset every time the batteries are disconnected. I upgraded to the timbo apps when the sensor was changed. it's only charging at 13.5 volts. That's with the grid heaters disconnected. Havnt run it longer than 10min as I can't get it further from the house with the dead pedal... the longer battery cables are 4/0 welding cable from the Battery to the starter and starter to tipm. Alternator to tipm. Checked grounds and all have continuity back to the battery.
No paint. Leaving the the patina.
