It appears the nss on my 84 300SD has toasted. Key on, dash lites and glowplugs go, key to start and solonoid doesn't engage. Lights don't dim, no click, nothing to indicate an additional drain on the battery. Putting it in neutral makes no difference.

Where can I plug in my ohm meter or volt meter to test it? Can I jumper around it to start the car? Could there be something else that could cause the same symptom?

Thanks
