Hi, I'd have to make sure the battery has a full charge and the battery connections are good. When the problem is ongoing, I'd have to check the voltage readings, solenoid S terminal-- solenoid bat terminal-- I'd also check the voltage reading at the starter field terminal. Compare those readings, with the reading across the battery terminals, key in the crank position. See if there is any voltage drop, anywhere?
