What is the charge rate ?, put the car up on ramps at front connect metre to live at solenoid and earth on metal, with the blue wire OFF start the van, then get underneath, and just watch the metre, now briefly touch a LIVE onto the alternator terminal marked IND, this is where the dash warning bulb connects to, it should then energise and start charging, if revved high enough it will start the charge cycle as well, as they have a resistor built in for a fail safe, if after touching a live onto IND it does nto start outputting even though it is rotating and connected ok it is duff.
