Hi i want to know if any have trouble with Fuel Pump output.

In my case when the FP is off i get 0V in output and when is on obteined 5V. But the problem is that 5v cant activate the relay.
Something similar happen with Idle PWM output, when i change the transistor that says in ms extra manual, but when test the port in test mode and get 5v volt on and off 0v.
In both circuits the signal out is gnd and not a 5v?
In the circuit schematic of manual says something of position jumpers in JP1. In my ms2 doughtboard the jumpers JP1 all cut this is normal?

Anyone can help me, becouse i dont understand muchos of electronic

Most of the MS2 outputs are grounding outputs. And this question has nothing to do with the jbperf.com products so you should post on the msextra forum.
