I used a bulb in series with 12v and tapped it to ac1. The bulb did not light up despite ac1 having - voltage. but when i checked the magnetic clutch from ecm(acmg) there was only negative voltage there producing less than 5v. However, even when nothing is connected to ac1, acmg still has 5v. It seems acmg is not reacting to ac1. Or should i be wiring THR (ac thermostor)?
Regarding the rpm, when i start the car it is less than 1000rpm, with a/c lower. When i drive around a few mins, rom stays at 1200 rpm. It goes down with ac on but returns to 1200 when compressor cycles off. This is regardless of low or high temp.
