Thanks Dale, I printed a copy of each diagram for my build. I vote for a sticky on this. Brent

I been trying to get the powers that be in control to start a electrical forum ...But no, everybody has to post their solutions in their own preferred forums.... So it gets repeated many times in many places..... So no need for sticky....

IF you need materials, wire, switches, connectors, lighting, whatever....

Thanks Dale. Your diagram is very clear cut and makes it look pretty easy. I am also running an electric fuel pump and I was told to use a rabbit relay just like this one pictured. Would you suggest the same thing?

I am kind of yes/no or fuel pump relays... It really depends on what you are doing with fuel pump/engine..... IF you are using those little Chinese "facet" pumps they hardly need a relay, if you are running big rotary for fuel injection, yes a relay is a good idea....

Any time you use a relay it savers *electrical* wear and tear on any switches (ign) because it handles most of the current load....

The particular relay you mention I have not used. By design and if wired correctly does have a really good feature of cutting off pump once engine dies ..... Since I am a believer in the plain simple old mechanical fuel pump (has always worked for me) its up to builder to determine what is appropriate for his/her build.... Nothing wrong with electrical pumps, I just never had the need for them... (yes my mech. pumps feed two big motors (2000cc +) with dual Weber 44's on one motor and dual 48 Weber's on other and never has run out of fuel)...

Found this little tidbit about relay...

http://www.ratwell.com/mirror/sfraser/relay.html

Try the relay, let us know how it works.....

No problem. I wanted to but I planned a trip to Florida a while back and it falls right on that April 4th/5th weekend which sucks b/c I really wanted to go. My brother is going and I will give him a list of stuff I need and to take lots of buggy pics. It'd be cool for everyone to see yours there.

This has been a very useful thread. It has saved me hours of headaches while wiring my buggy. I do have one issue that I have not resolved yet. I installed two headlight buckets on my manx clone. What I am trying to figure out is which wires on the back of a regular 7 inch round head lamp are high and low beam. The generic plug that I have has red, green, and black wires. The black is certainly ground. However, which of the remaining wires -red and green - high beam and low beam?

PostPosted: Fri Apr 03, 2009 4:21 pm    Post subject: Ignition coil wiring - no fuses? Reply with quote

I've been reading all the online buggy wiring diagrams and checking the haynes manual for all vintages of beetle and as near as I can tell the ignition coil and all the other things that use ignition "hot" in the engine compartment are not fused. I can't find any indication of fuseable links or any other means of protection for those loads. The ignition switch just switches hot from the battery right to the coil wire.

This strikes me as an appallingly bad idea. I don't want to make any false claims but perhaps this could be one of the reasons contributing to why so many vintage VWs go up in flames (especially busses). Lots of old cars have old and crappy fuel lines, but what makes the VW special regarding engine compartment fires?

That unsupported wire that dangles from your carb and goes to the fuel cutoff or automatic choke - if it grounds out against your carb body, the only limit to the current that will flow in that wire is its own resistance - its the skinniest wire in the circuit and will happily heat up red hot while the ignition switch supplies it all the current it can.

If I were you guys I wouldn't back an air-cooled VW out of the garage without putting an inline fuse on that wire before it heads back to the engine compartment. Its just too risky.

I realize the original designers wanted to have the car wired a certain way and the buggy wiring diagrams are faithful to the VW design, but fuses cost money and all air cooled VWs were engineered with costs as a primary constraint. Somebody at VW decided that a fuse was not required on that hot lead. Sure the car runs fine without it, but its pretty cheap insurance to go out and put an inline fuse holder in that line and cross one more potential failure mode off your list for about $5.

Go out to your late model car right now and count the number of fuses in the box and compare that to your VW. When was the last time you saw a honda accord or a toyota camry with an engine fire on the side of the road?

What size in-line fuse would you use for this wire - 8 amp?

I have seen many choke wires fried. I agree that a fuse is a great idea. An 8 is as high as I would go. I would want to try an inline 5 myself. But wonderul idea! I will add one myself today.
