Problem with cowl induction hood

[m22mike]

Yes, your not getting a good ground. The solenoid bracket should have a small tit pressed into it so when you tighten up the solenoid that tit should bite into the solenoid housing. If your solenoid has paint on it, even clear that could be the problem.You might even remove any paint that is on the inside of that solenoid mount to improve the ground.
2nd place to check is the solenoid frame that screws to the hood. This is less likely to be the problem since there are so many screws holding it to the hood. The correct type screws will bite into the frame.
If you want to confirm all this, clip or hold a jumper to the solenoid and attach to a good ground and try it.
Seen this problem several times.
Let me know what you find.
