The battery is new with 10.5 vdc. I tried the used a portable charger and car wouldn't start. Here is the list of things that was checked on my 911.
1) DME pin 1,18,35 had 10.5vdc
2) DME pin 5,16,17 to GND @ .2 ohms
3) Replaced Speed and reference sensors
4) Coil had 10.5 vdc to GND
5) Install new DME relay yesterday
6)When tried to start with the new DME relay I don't hear the fuel pump. However, as soon as the battery is connected with DME relay pin 30,87, 87b jumped the fuel pump become active.
I performed a spark check and noticed the spark was very weak. Please review the picture.
Is it safe to assume the car battery need to be fully charge to @ 12 volt?
