losing ground

Post by EVILM3666 »

Hi,
I am trying to set up the nos circuty. I have the parts all soldered in but when i try to ingage it I don`t get a ground from the wire.
Here is the thing i found when i check the grounds at the board with the power off (key off) i have less then 1 ohm of res.
But with the board powered up (key on) I get 11 ohms and with the car running I get 25 ohms.
It is like something is using all the ground.
I am using spr2 on the board for the out wire.

This is the same on the stim and on the car.
I have had my car running for almost a year and it runs great. Had it on the dyno 368hp
