Vw alternator wiring diagram - The black twine getting into the fine terminal at the coil (#15) is from fuse #12, which receives power from the ignition switch. Word 3 black wires leading from that terminal - one to the automatic choke, one to the backup lighting, and one to the idle cut-off valve at the carburetor. The high quality terminal on the coil is just a handy place to gain energy to those 3 additives. The truth that those additives acquire electricity from a terminal on the coil has not anything to do with the operation of the coil itself. The 3 wires may want to each pass up to fuse #12 personally, however that would be very inconvenient. So vw chose this configuration.
A great concept. Dave has now replaced his ignition switch once more for the second time and has installed a 25-amp fuse in the cord from the ignition switch, just "upstream" of the energy block he mounted in his engine compartment.
In method of this engine re-wiring job, dave hooked up what he calls a "electricity block" at the left sparkling air nozzle to preserve all of the wiring straight. Following is a totally hard wiring diagram displaying the wiring format on the electricity block, observed by way of a picture of the power block after the engine compartment re-wiring changed into complete.
No longer lengthy after finishing his engine re-wiring, dave by chance pulled the wire to the automatic choke free whilst the key changed into on (dave had just finished timing the distributor); the twine, which turned into hot, of course, fell down and shorted against the alternator -- causing the ignition switch to burn out again! To save you this from happening inside the future, it was suggested to dave that he placed a 25-amp fuse in the cord that goes from the ignition transfer again to the engine compartment, proper near the switch at the plug. One of these fuse, the guy said, "will electricity the entirety, but blow if some thing screws up, so one can kill strength to the touchy stuff. Better to replace a fuse that a switch.".
Whilst a brief inside the twine to the backup lighting fixtures burned out the ignition switch and shut him down, dave determined that it would be prudent to rewire the whole engine compartment, seeing that he determined some of different areas wherein insulation had both worn off or burned off the wires. The "inventory" wiring association in the engine compartment (no cdi or compufire) is proven roughly within the following diagram. (See greater on the "stock" coil/distributor wiring under.).
