So at this point you've changed the fuse twice and each time that seemed to fix it? Can you tell use which fuse it is and what it seems to supply? If you take this fuse out, does the starter still work? There should be NO fuse in the starter line. I don't know what VW expected to protect that line, but they didn't provide a fuse for that. If you have rewired this so that there is now a fuse there, you may need to just install a bigger fuse. The starter draws a LOT of current for a brief moment, then it drops to just a lot of current. > The only time I have seen anything similar is when I installed a new > generator and had to polarise it before it would work.

Polarizing only affects the charging, which is not happening when you're trying to start the engine. If you read ~14V at the battery and the ground is negative, then there's nothing wrong with your polarization; don't be tempted to re-do this "just in case." This more often leads to damage than to improvements, because it's so easy to do it wrong. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
