battery light on??

Guest
Just wondering if anyone had some ideas for me..I have a vr 5l manaul executive and the battery light has been on for the last week and a half. Firstly i replaced the regulator, that didn't work. Then I replaced the complete alternator with one of those revamped jobbies, but the battery light is still on and the battery is not charging.:bang:
Please help..

The wire fron the alt to the battery must be broken or one of your fusible links has burnt out. Get a multimeter and check the cables for continuity. The wire which charges the battery goes from the large terminal on the alt straight to the battery and is always in circuit.

yeh the alternator , that black module thing that it plugs into is ****ed, happened to mine, put another one in that ****ed up too, so i just got another alternator for $50 instead of wasting money on those module things, and everything is 150% working better :D :p

The whistle comes on when the alternator is charging at maximum rate and if your engine loses power when this happens you have a short somewhere. Most electrical problems can be traced back to bad terminals on the battery - they must be clean and tight.....not just appear clean and tight but remove them, sandapare or wirebrush the contact surfaces, apply some vaseline/silicone/whatever and tighten them up. Also make sure the engine has a good earth to the body. The V6 may be an internal combustion engine but it gets its instructions from an electrical brain...and if that ain't getting the right food as in electricity then it won't act right.....at least thats the way I see it. (did I write that??)
