Hello guys, just found the forum while searching for electrical help with my car not starting. I have a no start no crank issue.
It's been running fine until yesterday.
Car is an Astra H 1.7 CDTI 2004.
With the ignition on, all dash lights are on but no crank.
Brand new battery fully charged, starter motor and solenoid works fine when connected direct to battery.
Using multi-meter across the starter relay switch terminals i get the following readings:
key out of ignition : 0 V
Ignition on ( with dash lights ) : 12.5 V
When key is turned to crank the starter : drops to 0 V
Now trying to bypass the key ignition to get the starter to work, but i don't understand the above results.
I assumed there should be zero voltage with ignition on, and then 12+ V when key is turned to crank, to send power to the solenoid, is this correct ?
Have checked all visible wiring and used jump cables all over the places to eliminate any bad earthing points, but still no crank
Thanks for any help guys, really need the car for work !
