No power to fuse box 1978 Super Beetle

[[email protected]]

Can anyone help me answer why there is no power to the fuse box

[Saucy Jack]

Going to have to give a little more than that, is the battery charged? Will it start? if it starts is there power from the generator? have you checked for broken wires? bad fuses?

Which fuses are you checking? With the ignition switch OFF only two fuses will have power.. fuse #8 & #9. If your tester does not detect current on the INPUT side of these fuses you will need to trace your wires.
Pull out the fuse box and look to the #9 fuse for a thick red/white wire. This wire comes from under the rear seat and brings all the current from the battery/alternator to the dash. Remove the wire from the fuse box and test the end for 12v. Note that this wire is NOT fused so do not let it touch anything metal.
If you cannot get a voltage reading from this red/white wire, lift the rear seat and find the other end of the wire. Look for a large rectangular white junction below the left rear seat. This junction is where current from the battery and the alternator come together. There are four (4) red/white wires at this junction:

battery positiive terminal
B+ stud of the alternator
+ terminal on diagnostic plug
#30 wire that runs to the #9 fuse

Test the junction for voltage.
If there is no voltage at the junction check the wire running between the battery positive (+) terminal and this junction. While the ignition switch is OFF this is where your current is coming from.

It won't hurt to wire brush any connectors you remove to clean them up.

Sorry new to this

Made sure battery fully charged
Have power to 8 & 9 fuse, 10, 11 & 12 no power
No power to fuel pump & coil, no dash lights when turn key to on position

Other question- there are 2 wires coming from the coil, is one of those supposed to go to the #12 fuse and where is the other coil supposed to go to?

We need a reference to continue the discussion. Below is the '76+ FI Super Beetle wiring diagram:

Don't be intimidated by the diagram. Just look at one area at a time. Find and get familiar with where the different fuses (S#) are in the diagram so you can find them quickly. They are organized by circuit and not numerically. Note that some fuses (3-4, 5-6, 8-9,11-12) have black lines connecting their tops (INPUT side) together. These represent the brass bars in the fuse box that connect the INPUT side of pairs of fuses together. This allows one power source wire to power two fuses. In general, power flows from the top of the diagram down the circuits and grounds to the chassis ground at the bottom of the diagram. This version of the wiring diagram allows easier troubleshooting as it actually shows you what happens INSIDE switches, but is a bit harder to FIND devices and understand where they are installed around the car. It expects you to know where devices are located.
