this has been a frustrating issue that keeps happening. my selanoid on my starter will only click until the glow plugs turn off. then i can start my car. i put in new positive and negative cables ground strap and new bosch starter. it will do it cold or hot. any thoughts? battery is testing at 14v at terminals while idling and its 12.64 after sitting overnight... if i put my jump box with 1200cca on it the car starts right away.
