2102 390BH starting issue
Over the winter I had a slight starting issue- that I assumed was low battery voltage. I would turn the key on- let the glow plugs warm- battery voltage would drop to 11.7-12 volts and when I turned the key to engage the started nothing would happen. So i would turn the key off and then back on right to the starter and it would start fine.
But to day I have the same problem but the voltage was 12.6- 12.7. ( on dash display) and it took several time to get it started ( engine not tuning over).
do you think it could be a simple as a the ignition switch? of off to freightliner?
