Hi All, it's a long time since I posted! I have a Gen2 2.4TD surf (LN130) (non efi) and am having problems with the charge lead from the alternator. When I say the charge lead I mean the lead that has minimal positive voltage until the alternator is rotating - not the one that actually charges the battery and runs the equipment!
The lead that goes to the primary battery is fine and someone had previously fitted a split charge relay which I have upgraded. Unfortunately it seems to switch when the ignition is activated, not when the alternator is running. ON testing I have found the on the alternator side of the fuse when removed (7.5A marked 'charge' in the engine bay) the voltage appears to be approx 0-2.4 volts when the igntion is on or off (and immobiliser deactivated), and 13.5 when the engine is idling. The other side of the fuse is another matter entirely. This seems to lead to the dashboard and goes positive as soon as the ignition is switched on.When the fuse is inserted of course, the split charge relay switches when the ignition is turned on. I am guessing this is not correct!
Does anyone have any ideas as I can't find another lead that is only on when the engine is running and it's almost pointless having a split charge relay that doesn't stay detatched when the ignition is just 'on' !
