Hello new to this sight. So i'm new owner of a 71 super beetle and as the title shows having a serious issue. When i use the left turn signal the fuse for the turn signals blows and the hole car shuts off. I'm thinking that maybe i when did the alternator conversion that i messed up the wiring and is causing the short there. So yea i really need some help i' still semi new to electrical stuff.

First thing would be to remove both left turn signal bulbs and see if starting VW and pushing the turn signal to left still causes the fuse to blow. If not, replace one at a time and do same check, to isolate whether front or rear. If they both show this issue, I'd trace out/check the wire in the trunk that goes to left bulbs, might have a bad wire connection. We've seen two wires simply twisted together with no covering to expertly-soldered connections covered with heat shrink.


Look at the two sockets themselves, and make sure that the dual-filament bulbs have been inserted correctly, no junk sitting under the bulbs, etc..

You have a couple issues here. First is the dead short somewhere in the left turn signal system which you can sort as Cusser says.

The second problem is that it shuts off the car. This would indicate that someone has mis-wired something (either you or PO). As VW wired it, the wire that runs to the ignition coil is not fused. The car should run just fine with no fuses at all. So probably someone has hooked up your ignition coil power wire to the fused side of the fuse box rather than the unfused side.

You will want to fix that, as you don't want to be in a situation where a blown fuse causes the engine to stop, like when pulling out on the road in front of a truck for example. Shocked

sjbartnik - yes, I missed that "hole car" (whole car) issue, agree that the wire to coil #15 has been wired to fused side of the same fuse as the turn signals.

If one wants to add a dedicated inline fuse for that coil wire, should be on the factory unfused terminal on the fuse box.
