| I tried to test pump at home with a 12V dc source, however I couldn't start it, there are 3 wires, positive, ground and say pulse the last one... I think pulse wire says the direction (suck/pump). I couldnt produce the pulse signal and it didn't run at home.
Next time in the car, I'll close the air output holes and see what will happen...
By the way nice to meet you Lofty, I follow your site and no doubt it's great! Last week I have had another problem, I lost the "heater". It blows at the max position but there is no heat. Went to a garage but it has worked again there. When came back, it has gone again. I couldnt wipe the mist away from windscreen last week then I bought a liquid thingy. What you think? |
