hello


i got this 3 port valve,

P251SS-012-D

it is a ingersollrand

12 volt and 36 ohm


i have been running a mac valve thats 12v and 25 ohm

so the ingersollrand eat's 0,33 amp max
and the mac 0,48..

car is a evo lhd 6

been running the mac just fine,
and i wanted to test the ingersollrand for a friend.

it killed the valve output in the ecu.....

but why???

what i'm i missing???

cheers,
Robin

 

you needed to wire a resistor in with the ingersoll

 

but the MAC valve i was using for a year now dont have one..

and that one draws even more amp then the ingersollrand one

 

What does the rand spike at though? What does it take at the start?

 

well the scoop @ my work did not see it...

so its realy short or it has non
