I was afraid of that, so I tried putting the wires from the alternator together and then going to the light, but this didn't work; no charging, no volt-reading on the gauge... At Idle without any accesoiries running we got 13.4V at the starter-post, revving the engine produced between 14.6 and 14.8V, dropping to 14.2V with the lights and highbeams on. > Without the brown /yellow wire hooked up the light won't come on and > the alternator won't charge.

Allready knew that from you ;-) Now I could REALLY use some suggestions; without the light-wire I get no charging, without the sense-wire there's no charging either! But I'd hate to burn up the regulator; should I put in a resistor of some sort? Any suggestions? I didn't pay much attention to the brand of alternator, but I know it's an aftermarkert one, no Ducellier of Motorola. The owner bought it locally. If important I could ask him what brand/type it is... Thanks for the help, JAN van de Wouw Thinking Different... Using a Mac... Living the Dream...
